1. Field
This invention relates to a method and system of providing a mattress and more particularly, to a mattress using a plurality of foam springs to provide comfort and support to the user of the bed.
2. Background
Consumers, manufacturers, and distributors may each individually or as groups have many different opinions of the type of a bed and bed firmness that may provide for a comfortable resting or sleeping condition. There are many different types of beds and firmnesses to choose from when deciding on a bed to purchase. In an attempt to provide users with comfortable beds, bed manufacturers may use metal springs, foam layers, solid foam blocks, water, air, or other means to provide various types of firmness to a user. These different types of bedding materials may be used individually or in combination. Beds may be available in various firmnesses using a combination of springs, foams and materials in various combinations may provide for firmer or less firm support to the user. However, even though great effort has been dedicated to making a mattress that provides good support and comfort, the present solutions are inadequate and a need exists for an improved mattress.
An aspect of the present invention relates to providing a mattress wherein the mattress has foam barrels or springs on its interior to provide support and comfort to a user. In embodiments, the foam barrels within a mattress may be provided with varying degrees of firmness. For example, one region of the mattress may be populated with barrels that are more firm or resilient with respect to other barrels within the mattress. In embodiments, foam barrels of varying firmness may be placed within a given region of the mattress. It is envisioned, for example, that one side of the mattress may be set to a ‘firm’ user setting by using more resilient foam barrels on the ‘firm side and another side of the bed may be set to a ‘soft’ user setting by using barrels that are less resilient in the ‘soft’ side. Regions of the mattress may be similarly adjusted. For example, the areas in the region of a person's lower back may be set to be more firm or less firm by populating the lower back region with appropriate foam barrels. Other such regions of the mattress could be targeted for firmness adjustment (e.g. regions around the head, neck, upper back, mid-back, lower back, torso, gluteus, upper leg, mid-leg, lower leg, etc.).
Another aspect of the present invention involves providing adjustable firmness mattresses through the use of varied firmness foam barrels. Embodiments involve providing user interfaces to allow a person to select firmness settings and manufacturing techniques for setting the mattresses firmness per the user requests. In embodiments, the barrels may be positionable by a manufacturer, distributor, delivery/set-up personnel, the user or other person.
Another aspect of the present invention involves establishing categories of mattress firmness types and then providing the firmness types through the use of foam barrels. For example, a firmness type may be any one of the following: single firmness, dual firmness zones or sides, multi-firmness regions and the like. Each firmness type may be established to suit a particular population segment (e.g. firm on side one and soft on side two) and mattresses may be manufactured per the firmness types using the foam barrels such that a product offering of typical mattress types can be made. In embodiments “zoning” or “pattern” configurations for large “groups” of users are determined and mattresses are made using foam barrels according to the configurations and they are mass produced. A user may determine which type of zoned or patterned mattress best suits their particular needs. In embodiments, planning systems are provided to help users determine, via software or some other method, what pattern best suits their comfort needs.
A mattress disclosed herein may include a plurality of foam barrels, possibly of variable firmness, resting in webbing or other alignment systems, wherein the foam barrels are covered by fabric on all sides forming a foam encasement or outer covering of the mattress. In one embodiment, the webbing may not be connected to the encasement or other device along the sides; it may be permitted to ‘float’ within the outer encasement.

Referring now to
A bed facility 102 may be any type of bed that may provide a comfortable position for a user to rest, sleep, sit, convalesce, or the like. The bed facility 102 may include a standard bed, an adjustable bed, or the like. The bed facility 102 may be in any shape or size that may include a crib bed, twin bed, full size bed, queen size bed, king size bed, or the like. In an embodiment, the bed facility 102 may typically include a mattress, box spring, support frame, and the like. In an embodiment, the mattress may include a material top layer (e.g. foam or material), material bottom layer, springs, foam layers, and the like.
In an embodiment, a standard non-adjustable bed may be any bed that maintains a single rigid position that may not be capable of changing its shape or position. Additionally, the non-adjustable bed may be any rigid shape that may have a non-flat configuration.
In an embodiment, an adjustable bed may be a type of bed that is capable of adjusting at least one aspect of the bed shape such as a head section, a foot section, leg section, a torso section, or the like. In an embodiment, there may be a control interface that a user may use to adjust the position of at least one aspect of the bed.
In an embodiment, the foam springs 108 may be any type of soft foam that may include latex foam, urethane foam, visco-elastic foam, polyurethane foam, or the like. In an embodiment, the foam springs 108 may be used for bedding, pillows, chairs, couches, or the like. In an embodiment, the foam springs 108 may be considered a foam support for the bed facility 102.
In an embodiment, the foam springs 108 may be made of the solid foam material but may additionally have interior openings, exterior openings, interior and exterior opening, or the like. The openings may not be important to the firmness of the foam spring 108 but may be useful for manufacturability of the foam spring, providing space for added foam spring movement, contain health related materials, and the like.
In an embodiment, a mattress outer case may be a part of the bed facility 102 mattress that provides the volume space to place the foam springs 108. In an embodiment, the mattress outer case may be the mattress, a separate bed structure from the mattress, or the like. The mattress outer case may have a shape that is substantially the same as the bed facility 102. In an embodiment, the foam spring 108 may have a height that may equal to the height of the mattress outer case, may be a portion of the height of the mattress outer case, may have a height greater than the mattress outer case, or the like. In an embodiment, the cross section of the foam spring 108 may have any shape that may include a round shape, a square shape, a hexagon shape, an octagon shape, a star shape, an oval shape, or the like. In an embodiment, a plurality of foam springs 108 may be contained within the mattress outer case. The plurality of foam springs 108 may be all the same shape, a combination of shapes, or the like. In some cases, the foam spring 108 shapes may be combined to provide for spaces between the foam springs 108 that may allow the foam springs 108 to have freedom of motion. For example, the plurality of foam springs 108 may be all circle shaped or a combination of circle and oval shaped foam springs 108 to provide spaces between the foam springs 108 to allow motion areas for the foam springs 108. In other cases, it may be desired for the foam springs 108 shapes to be selected where the foam springs 108 are in close contact with each other to allow each of the foam springs 108 to support the adjacent foam springs 108. For example, the plurality of foam springs 108 may be all square foam springs 108 that contact adjacent foam springs 108 on all four sides; this may provide support to the foam spring 108 and all the adjacent foam springs.
In an embodiment, the plurality of foam springs 108 contained within the mattress outer case may have a plurality of different firmnesses. In an embodiment, the foam spring 108 firmness may be defined by an indentation load deflection (ILD) value, indentation force deflection (IFD) value, foam density, or the like. IFD, and in a similar manner ILD, is defined as the amount of force, in pounds, required to indent a fifty square inch, round surface into a foam material a certain percentage of the foam material total thickness. IFD may be specified as the number of pounds at a specific deflection percentage for specific height foam. For example, the IFD for a certain foam may be defined as 25 pounds/50 in2 at a 25% deflection on a four inch thick piece. In an embodiment, the IFD may be influenced by the thickness of the foam material, the size of the material, and the like. For some types of materials, such as latex foam, the ILD value may correlate with the density of the material used. For others, the ILD may be less dependent, or even independent, of the density of the material used.
The firmness may also be measured or described by the density of the foam, in pounds per cubic foot, kilograms per cubic meter, or some other relevant standard. Although the density may not be a direct measurement of firmness, it may have a direct relationship to firmness. For example, a 110 kg/m3 density barrel may be firmer than a 95 kg/m3 barrel and the 95 kg/m3 barrel may be firmer than a 80 kg/m3 density barrel, and the like.
In an embodiment, the plurality of foam springs 108 may be configured within the mattress outer case to provide localized variable firmnesses for the bed facility 102. In an embodiment, the firmness of a bed facility 102 may be varied to provide comfort for a user that may be experiencing discomfort as a result of an accident, arthritis, surgery, chronic conditions, a neck condition, a knee condition, a sleep disorder, a disease, or the like. In some cases, the discomfort experienced by the user may not be static but may be part of a changing condition that may have the user experiencing more or less discomfort over time.
In many cases the discomfort the user may experience may be a local discomfort such as lower back pain, hip pain, neck pain, shoulder pain, and the like where it may be advantageous to have different firmness in these areas to provide an improved resting comfort in the local position. For example, the user may experience lower back pain and the plurality of foam springs 108, with a certain firmness, may be configured to provide less firm or firmer support in the lower back area to help provide a comfortable resting position.
In an embodiment, the user's discomfort may change over time, and the plurality of foam springs 108 may be modified to compensate for the changing user condition. For example, if the user is suffering from lower back pain, the initial foam spring 108 configuration may provide firmer support in the area of the lower back to position the back for improved healing. Over time, the user's lower back may improve and the foam springs 108 firmness in the area of the lower back may be modified by gradually providing less firm support until the form spring 108 firmness is the same as the remainder of the bed facility 102.
In an embodiment, when considering the location to place the various foam spring 108 firmnesses, the user's physical characteristics (e.g. height, weight, body shape, gender) may be considered for the proper placement and firmness of the foam spring 108. For example, the placement for the foam springs 108 for a user's lower back may be influenced by the user's height, typical sleeping position, size of the bed, shape of the bed, location the user sleeps on the bed (e.g. towards the head or foot of the bed), and the like.
It may be understood that the foam spring 108 configuration may be varied to account for more than one user condition of discomfort. For example, a user may have more than one body location that is effected by arthritis. The plurality of foam springs 108 may be configured to provide comfortable resting conditions to any or all of the body locations that the user desires discomfort relief. As these conditions may improve or worsen over time, the user may be able to change the foam spring 108 configuration, change the firmness of the foam spring 108 in certain bed facility 102 locations, or the like. As another example, a user may be experiencing discomfort from a chronic condition (e.g. arthritis) and a short-term condition (e.g. surgery). As the short term condition improves, the foam springs 108 in the short-term location may be changed as needed to provide the user with the desired comfort. In a similar manner, as the chronic condition may change with time, the foam springs 108 may be changed in these locations to provide the best comfort position for the user.
In another embodiment, the springs used within the bed facility 102 may be pneumatic or hydraulic springs that may be have adjustable firmness settings. A bed facility 102 may have a pattern of pneumatic or hydraulic springs that may be orientated using a containment facility 104. In an embodiment, the user may be able to adjust the individual firmnesses of the pneumatic or hydraulic springs to meet the comfort requirements of the user. In an embodiment, there may be a computer device interface where the user may be able to indicate the required firmness for certain locations of the bed facility 102. In an embodiment, the computer device may be a desktop computer, laptop computer, server, webserver, personal digital assistant (PDA), smartphone, handheld computer, or the like. The computer devices may include connections to a network for accessing other computer devices that may store or manage bed facility 102 information. In an embodiment, the networks may include a WAN, LAN, Internet, intranet, peer-to-peer, or other network connecting computer devices. In an embodiment, the computer device and networks may be wired or wirelessly connected. In an embodiment, using the network, the user may be able to access computer devices on the network to receive spring firmness settings. For example, the user may access the Internet from the computer device and may download a particular set of spring firmness settings that may match a desired comfort requirement. In an embodiment, the computer device interface may show a grid substantially the same as the orientation of the pneumatic or hydraulic springs where the user may be able to indicate the firmness of the individual springs, groups of springs, zones of springs, areas of springs, the entire bed facility 102, or the like. In an embodiment, the user may work with the computer device interface using a keyboard, mouse, joystick, touch screen, or other input device. In an embodiment, based on the user's indications, the computer device interface may control the pressure of the individual pneumatic or hydraulic springs to provide the desired comfort. In an embodiment, there may be preset firmness configurations that may be selected on the computer device interface; the preset configurations may be user set, historical settings saved by the computer device, preset at the manufacturer, preset at the bed facility 102 enterprise, or the like. In an embodiment, the user may change the firmness configuration as often as the user requires.
In addition to varying the foam spring 108 firmness in a bed facility 102, the foam spring may also contain additional health benefit materials that may provide an improved healing environment. In an embodiment, the additional health benefit materials may include activated carbon, tourmaline, magnets, and the like. In an embodiment, the additional health benefit materials may be used individually or in combination within the foam spring 108, the bed facility 102, or the like.
Activated carbon 110 is a material that has an exceptionally high surface area that includes a large amount of micro porosity. Sufficient activation for useful applications may come from the high surface area but further chemical treatment may used to enhance the absorbing properties of the activated carbon. Activated carbon attracts and holds certain chemicals therefore reducing dust, odors, contaminates, and the like from the area around the activated carbon. The contaminants may be attracted to and held (adsorbed) on the surface of the carbon particles.

In an embodiment, beds may be made of various different sizes such as twin, full, queen, king, and the like for different situations and user requirements. The bed sizes may be industry standard sizes but there may also be more than one standard size for a bed type such as a long twin bed verses a standard sized twin bed.
A standard non-adjustable bed may be any bed that maintains a single rigid position that may not be capable of changing shape or position. In an embodiment, the standard non-adjustable bed may typically be used in a bedroom for sleeping, resting, or the like and may provide a flat horizontal surface for the user to lie down on. Additionally, the non-adjustable bed may be a single rigid shape that may have a non-flat configuration. Typically, the standard non-adjustable bed may be rectangular in shape, but may also be in other shapes such as round, square, or the like.
An adjustable bed may be a type of bed that capable of adjusting at least one aspect of the bed shape such as a head section, a foot section, leg section, a torso section, or the like. In an embodiment, there may be a control interface that a user may use to adjust the position of at least one aspect of the bed. In an embodiment, the bed position adjustment may be to provide a more comfortable position to the user for performing a task (e.g. writing at a work station), relief from pain, watching TV, provide a different sleeping position, improved blood circulation (e.g. elevated head or feet), and the like. In an embodiment, the bed structure may be flexible, hinged, or the like to provide locations for the adjustable bed to move into different positions.
In an embodiment, the bed facility 102 may use a mattress that contains foam springs 108 to support the user. In an embodiment, the foam spring 108 may be made of any type of soft foam that may include latex foam, urethane foam, visco-elastic foam, polyurethane foam, or the like. In an embodiment, the foam spring 108 may be contained in a mattress outer casing; the mattress outer casing may be in the shape of the bed. In an embodiment, the foam spring 108 may provide direct support to the user, provide indirect support by supporting an over layer of material, or the like. In an embodiment, the foam spring 108 may typically be of a height to fit between the top and bottom surfaces of the mattress outer casing. In another embodiment, the foam spring 108 may be a portion of the height of the mattress outer casing and more than one foam spring may be placed on top of another to fill the space between the top and bottom of the mattress outer casing.
In an embodiment, the foam spring 108 may have a cross sectional shape that may include round, square, hexagon, octagon, star shaped, oval, or the like. In an embodiment, foam springs 108 may be used in any facility that a user may require soft supportive characteristics such as beds, pillows, chairs, couches, and the like. In an embodiment, there may be a plurality of foam springs 108 used in a mattress outer casing to provide support to a user. The plurality of foam springs that may be used within the volume of the mattress outer casing may be a combination of cross sectional shapes. For example, the mattress outer casing volume may use a combination round and oval shaped foam springs 108 to provide a different foam spring 108 configuration to different parts of the mattress. In an embodiment, the plurality of foam springs 108 may fit together such that there may be spaces between the foam springs 108; the spaces may provide freedom of motion for the plurality of foam springs. In another embodiment, the shape of the foam springs 108 may be selected that provides for the foam springs 108 to fit tightly together; the tight fit may allow each foam spring 108 to provide support to adjacent foam springs 108. In an embodiment, the cross sectional shape of the foam springs 108 selected for placement within a mattress outer casing may provide for differing support characteristics to the user. For example, looser fitting foam springs 108 may provide for a softer support structure to the user while the tighter fitting foam springs 108 may provide a firmer support structure.
In an embodiment, the foam spring 108 may be solid foam, may contain interior openings, may contain exterior openings, may contain a combination of interior and exterior openings, or the like. In an embodiment, the foam spring 108 interior and exterior openings may not influence the spring foam 108 firmness but may be used for manufacturability, to provide space to allow movement of the foam spring 108, or the like. For example, an interior opening of the foam spring 108 may be used during manufacturing to provide for mold shapes, allow additional area for air injection, or the like. In an embodiment, the interior and exterior openings may be used to provide holding area for health benefit materials such as activated carbon, tourmaline, magnets, and the like.
In an embodiment, the foam springs 108 may have differing firmness that may be defined by an indentation load deflection (ILD) value, indentation force deflection (IFD) value, foam density, or the like. IFD, and in a similar manner ILD, is defined as the amount of force, in pounds, required to indent a fifty square inch, round surface into a foam material a certain percentage of the foam material total thickness. IFD may be specified as the number of pounds at a specific deflection percentage for specific height foam. For example, the IFD for a foam may be defined as 25 pounds/50 in2 at a 25% deflection on a four inch thick piece. In an embodiment, the IFD may be influenced by the thickness of the foam material, the size of the material, and the like.
The firmness may also be measured or described by the density of the foam, in pounds per cubic foot, kilograms per cubic meter, or some other relevant standard. Although the density may not be a direct measurement of firmness, it may have a direct relationship to firmness. For example, a 110 kg/m3 density barrel may be firmer than a 95 kg/m3 barrel and the 95 kg/m3 barrel may be firmer than an 80 kg/m3 density barrel, and the like.
In an embodiment, the different IFD foam density, or the like, and therefore foam spring 108 firmness, may be varied or adjusted by using different density foam, different types of foam, or the like. In an embodiment, the foam spring 108 density may be varied by using different percentages of air when manufacturing the foam spring 108; the amount air used during the foam manufacture may provide the amount or size of cells within the foam spring 108. For example, a foam spring 108 with more air, and therefore more foam cells, may provide for lower density foam and therefore may be less firm.
In an embodiment, the foam spring 108 may include an attachment facility 120 to allow more than one foam spring 108 to be associated with other foam springs 108 within a mattress outer casing; the attachment may be used to maintain the orientation of one foam spring 108 to another foam spring 108, the alignment of various firmness foam springs 108, or the like. In an embodiment, the attachment facility 120 may be a feature on the outer surface of the foam spring 108 such as a geometric shaped raised foam area, geometric shaped recessed foam area, attached Velcro material, mechanical snaps, clips, buckles, glue, adhesive, tape, or the like.
A containment facility 104 may be a mechanical device that may be used to contain, orient, and maintain the plurality of foam springs 108 in a pattern within the volume of the mattress outer casing. In an embodiment, the containment facility 104 may be a rigid device, semi-rigid device, flexible device, or the like that may be preset, set by the user, preset and adjusted by the user, or the like. In an embodiment, a rigid containment facility 104 may be made of metal, plastic, or the like. In an embodiment, a flexible containment facility 104 may be a cable, a rope, a strap, a web, or the like. In an embodiment, the rigid and flexible containment facilities 104 may be combined by having a rigid structure such as a plastic patterned containment facility 104 combined with a flexible component such as a strap to attach to the foam spring 108.
In an embodiment, the containment facility 104 may attach to each foam spring 108 attachment facility 120 and may be used to grip the foam spring 108 attachment facility 120, fit into the foam spring 108 attachment facility 120, fit around the foam spring 108 attachment facility 120, connect to the foam spring 108 attachment facility 120, or the like.
In an embodiment, the containment facility 104 pattern may be preset, user set, fixed, adjustable, a combination of preset and adjustable, or the like. For example, the containment facility 104 may be delivered to the user with a preset pattern but the user may be able to adjust the containment facility 104 pattern to position the foam springs 108 in a user desired pattern.
Activated carbon 110 is a material that has an exceptionally high surface area that includes a large amount of micro porosity. Sufficient activation for useful applications may come from the high surface area but further chemical treatment may used to enhance the absorbing properties of the activated carbon. Activated carbon attracts and holds certain chemicals therefore reducing dust, odors, contaminates, and the like from the area around the activated carbon. The contaminants may be attracted to and held (adsorbed) on the surface of the carbon particles. The characteristics of the carbon material (e.g. particle size, pore size, surface area, surface chemistry, density, and hardness) influence the efficiency of adsorption.
In an embodiment, the activated carbon 110 may be mixed with the foam spring 108 material for the removal of contaminants from the bed facility 102 environment. In another embodiment, the activated carbon 110 may be added to the foam spring 108 as a separate filtering device. For example, the foam spring 108 may have an opening where activated carbon 110 may be added to act as a filter to remove contaminates from the air within and around the bed facility 102. The foam spring manufacturer, bed facility 102 enterprise, user, or the like may add the activated carbon 110 to the foam spring 108. In this embodiment, the activated carbon 110 may be replaceable.
In an embodiment, the activated carbon may be a coating on the foam spring, may be inserted into the annulus of the foam spring, may be a ring around the perimeter of the foam spring, or the like.

In an embodiment, the tourmaline 112 may be mixed with the foam spring 108 material during the foam spring 108 manufacture. In another embodiment, the tourmaline 112 may be added to the foam spring 108 as a separate device. For example, the foam spring 108 may have an opening where tourmaline 112 may be added to add the health benefits of tourmaline to the bed facility 102. The foam spring manufacturer, bed facility 102 enterprise, user, or the like may add the tourmaline 112 to the foam spring 108. In this embodiment, the tourmaline 112 may be replaceable.
In an embodiment, the tourmaline may be a coating on the foam spring, may be inserted into the annulus of the foam spring, may be a ring around the perimeter of the foam spring, or the like.
Magnets 114 are believed to be useful for increased circulation, reduced inflammation, increased recovery speed from injuries, and the like. In an embodiment, the magnets 114 may be mixed with the foam spring 108 material during the foam spring 108 manufacture, placed in specific locations in the foam spring 108 during manufacture, or the like. In another embodiment, the magnets 112 may be added to the foam spring 108 as a separate device. For example, the foam spring 108 may have an opening where magnets 112 may be added to add the health benefits of magnets 112 to the bed facility 102. The foam spring manufacturer, bed facility 102 enterprise, user, or the like may add the magnets 112 to the foam spring 108. In this embodiment, the magnets 114 may be replaceable.
In an embodiment, the magnets may be a coating on the foam spring, may be inserted into the annulus of the foam spring, may be a ring around the perimeter of the foam spring, or the like.
In an embodiment, the pattern of magnet placement within the foam spring 108 and within the bed facility 102 may be important to the magnet health benefits. In an embodiment, a magnet orientation application may be used to determine the placement of the magnets within the foam spring 108, bed facility 102, and the like. In an embodiment, the magnets may be placed to provide an increased magnet influence to provide health benefits in certain locations. In an embodiment, the magnet orientation application may determine the location of magnets within each individual foam spring 108.
A foam spring orientation application software 118 may be used to determine the placement of the plurality of foam springs 108 within the mattress outer case volume. In an embodiment, the plurality of foam springs 108 may be of differing firmnesses and the foam spring orientation application software 118 may be used to determine the proper placement of the different foam spring 108 firmnesses to meet the users comfort requirements. For example, the user may require certain locations of the mattress to be less firm, more firm, or the like to help provide the proper support for a part of his or her body that may be experiencing discomfort such as a hip, shoulder, back, neck, knee, or the like. The user may have had an accident, surgery, suffer from arthritis, have a neck condition, have a knee condition, have a sleep disorder, a disease or the like and different firmnesses within the bed facility 102 may be required to provide the proper comfort for these areas of discomfort.
In an embodiment, the foam spring orientation application software 118 may present questions to a user to determine the comfort requirements of the user's bed facility 102. The questions may be presented to the user as a paper questionnaire, a computer questionnaire, indicating on a chart of the body the areas needing comfort consideration, or the like.
In an embodiment, the questionnaire may contain preset questions that may be input to a computer device from a completed paper questionnaire, interactively on the computer device, or the like. In an embodiment, the computer device interactive questionnaire may present additional questions to the user based on the answer to a previous question. For example, a first question may ask if the user suffers from discomfort in his or her back. If, for example, the user answers yes, the questionnaire may continue to ask questions that are particular to back discomfort such as location of pain, pain levels, if the pain is sharp, if the pain is dull, if the pain increases with time, and the like.
In an embodiment, the user may indicate on a body chart the areas of discomfort that may require various foam spring 108 firmnesses. In an embodiment, the user may indicate the location, the type of discomfort, the intensity of discomfort, and the like that the form spring orientation application software 118 may be able to interpret into bed facility 102 firmness requirements. In an embodiment, the body chart may be divided into a grid, sections, zones, or the like to allow the user to define the location of discomfort.
In an embodiment, after the questionnaire is complete, the application software 118 may determine at least one configuration of foam springs 108 for the bed facility 102. The configuration my include foam springs 108 of varying firmness to provide a firmness configuration that may match the firmness requirements of the user. For example, if the user indicated in the questionnaire that he or she suffered from back pain in the lower back area, the foam spring orientation application software 118 may configure less firm or firmer foam springs in the area of the lower back. The remainder of the bed facility 102 may be configured to have a standard firmness to properly support the remainder of the user's body. This configuration of varying firmness across the bed facility 102 may provide the user with a comfortable position to rest, sleep, or the like.
In an embodiment, after the foam spring orientation application software 118 has determined the foam spring 108 configuration for the user, a test configuration may be setup in the bed facility 102 enterprise for the user to try the form spring 108 configuration. Based on the user trying the foam spring 108 configuration at the bed facility 102 enterprise, the foam spring 108 configuration may be modified to improve the bed facility 102 comfort.
In an embodiment, the foam spring 108 configuration may be manually modified by the user or the bed facility enterprise by interchanging form springs 108 and retrying the comfort of the bed facility 102 until a desired comfort has been reached. In another embodiment, the answers to the foam spring orientation application software 118 may be revised and the foam spring orientation application software 118 may provide a new foam spring 108 configuration for the user to try. In another embodiment, the foam spring orientation application software 118 may have provided more than one foam spring 108 configurations and the user may try at least one of the additional configurations to determine if one of the additional configurations provides the desired comfort.
In an embodiment, the bed facility 102 foam spring 108 configuration may be iterated at the bed facility 102 enterprise until a foam spring 108 configuration is determined that provides the desired comfort. In an embodiment, once the final foam spring configuration has been determined, the order for the bed facility 102 with the user's desired foam spring 108 configuration may be placed with a manufacturer for delivery to the user, the configuration may be set in the bed facility 102 enterprise and delivered to the user, or the like.
In an embodiment, after the user has received the bed facility 102 with the user defined foam spring 108 configuration the user may be able to adjust the foam spring 108 configuration, change foam spring 108 firmnesses, or the like. The user may adjust the configuration or firmness of the bed facility 102 because of changing conditions (e.g. the discomfort improves or worsens), to provide a better comfort configuration, or the like. In an embodiment, the user may adjust the foam spring 108 configuration manually by changing the location of the foam springs 108, changing the firmness of the foam springs 108 in certain locations, or the like.
In another embodiment, the user may use the foam spring orientation application software 118 to reconfigure the foam spring 108 configuration. In an embodiment, the user may have been provided a copy of the foam spring orientation application software 118 that the user may operation on the users own computer device. The user may input revised answers to the questionnaire; the new questionnaire answers may be used to determine a new foam spring 108 configuration.
In another embodiment, the user may use a web based foam spring orientation application software 118 to revise answers to the questionnaire to determine a new foam spring 108 configuration. In an embodiment, the user's previous answers to the questionnaire may be stored in the web based foam spring orientation application software 118 and the user may be able to recall his or her answers and modify the answers. Using the modified answers, the web based foam spring orientation application software 118 may provide a new foam spring 108 configuration to the user.
In an embodiment, similar to the iterative method of determining the user's desired foam spring configuration at the bed facility 102 enterprise, the user may iterate into a new foam spring 108 configuration that matches the users comfort requirements.
