Meditation is an ancient practice that has been around for thousands of years. While definitions of and postures for meditation vary across different cultures and religion, one common position of meditation involves a meditator sitting in a cross-legged or kneeling position on the ground or on the floor. Meditation can be performed while sitting in a chair or lying down; however, there are several disadvantages to these positions. Sitting in a chair or on other furniture distorts natural posture. Humans' skeletal structure and muscular structure have evolved such that it causes less discomfort for humans to sit on the ground or in a squatting position. Sitting in a chair or on other furniture causes tightening of the hip flexors, weakening of the core, back, and neck muscles, and compression of spinal discs over time. Over time, this can lead to pain throughout the body, including pain in the hips, shoulders, back and neck. Additionally, sitting in a chair or on another piece of furniture causes the brain to shift to work mode, as a sitting position is often associated with work. Conversely, lying down while meditating is disadvantageous because this position is associated with sleep. Therefore, lying down causes the brain to shift to sleep mode, making this position not ideal for meditation.
On the other hand, meditation in a cross-legged position or lotus position provides the benefits of a natural posture as well as activating the parasympathetic nervous system. This provides for reduced anxiety and a calmer, more relaxed state. However, many people find it difficult to maintain a cross-legged position or lotus position for a period of time long enough to meditate because people are not accustomed to sitting in this position and their muscles are not sufficiently developed or not sufficiently flexible to maintain this position. This is particularly true for adult men. Typically, people who are not flexible enough to meditate in a cross-legged or lotus position have been forced to meditate on a piece of furniture, lying down, or have assembled a hodgepodge of pillows, blankets, or cushions to attempt to provide sufficient support to meditate in a cross-legged or lotus position. However, this hodgepodge assembly is difficult to consistently reproduce in the same or a similar configuration, time consuming to reproduce in the same or a similar configuration, and typically not sufficiently supportive of the knees or hips.
Sitting on a cushion may provide some support for users in a cross-legged position. However, when sitting cross legged on a cushion, many Westerners elevate their butts, resulting in the knees shooting up into the air after only a few minutes of sitting in this position. This results in a lack of comfort in the back, hips, knees, and ankles. While some knee blocks have attempted to address these issues, these knee blocks don't fit most tight-hipped people and are not readily customizable. Some knee blocks require removal or addition of fill material to adjust the shape or angle of the knee block. Additionally, many knee blocks are not customizable at all, and therefore do not provide adequate comfort for users in a cross-legged position.
Accordingly, there is a need for a seating system which allows a user to be close to the ground or floor and which provides support for a user in a cross-legged or kneeling position. There is also a need for a seating system including a seat with an adjustable height which provides back support, and a seating system including knee supports which are adjustable to support the height of a variety of users' knees when the users are in a cross-legged, kneeling, or lotus position. Finally, there is a need for a seating system which is compact and portable such that it can be easily assembled, disassembled, and transported.
Referring now to the drawings in general, the illustrations are for the purpose of describing one or more preferred embodiments of the invention and are not intended to limit the invention thereto.
The present invention is directed to a seat system providing support for users seated in a cross-legged, kneeling, or lotus position. The seat system includes a base including a plurality of adjustable risers, a seat with a back operable to rotate 180 degrees, hinged knee blocks, and a foldable base operable to include the other components when in a folded or collapsed state.
FIG. 1A illustrates a front perspective view of a seat system 100 according to one embodiment of the present invention, including a seat 102 connected to a backrest 104 via a spine 106, risers 108, a base 110, and adjustable knee blocks 112. In one embodiment, the seat system is operable for use by a user with just the base 110. In another embodiment, the seat system is operable for use by a user with the base 110 and knee blocks 112. Advantageously, the knee blocks 112 are operable to be positioned on the base in any position to support a user of the seat system 100. The weight of a user's body naturally holds the knee blocks 112 in place such that the knee blocks do not require any additional material or fasteners to stay in place, and the knee blocks are not attached or affixed to any other component when in use. The knee blocks 112, or MAKs, provide increased hip support for users and are operable to configure into a variety of positions. In one embodiment, the base 110 is operable to be used as a stand-alone seat system, where a user can kneel or sit in any other comfortable position without requiring users to set up the knee blocks 112, riser plates 108, seat 102, and back rest 104.
In one embodiment, the seat 102 is operable to rotate 90 degrees, increasing the length of the seat 102 and enabling a user to sit or kneel length-wise on the seat 102. By rotating the seat 102 90 degrees, the base 110 enables users to drop their feet down, offering increased ankle support. Many people find the act of kneeling uncomfortable, including men, women, seniors, and younger people. When the seat 102 is rotated 90 degrees, users are able to flatten their knees, legs, and ankles out, providing greater support for these areas. In one embodiment, the seat 102 measures approximately 16 inches by 11 inches
In another embodiment, the seat system is operable for use as a workstation. The riser plates 108 are lightweight, stable, durable, and easy to stack. This functionality enables users to place a work device on top of the riser plates 108, adjusted to the user's desired height. Instead of meditation, the seat system is operable to enable users to work in a cross-legged or kneeling position, using the riser plates 108 and/or seat 102 as a platform for their work device.
FIG. 1B illustrates a front perspective view of a seat system according to another embodiment of the present invention. The seat system is operable to be used as a stand-alone seat system, enabling a user to kneel and/or sit in any other comfortable position without requiring users to set up the knee blocks 112. Users are then able to use the seat system as a meditation system and/or a workstation.

The above-mentioned examples are provided to serve the purpose of clarifying the aspects of the invention, and it will be apparent to one skilled in the art that they do not serve to limit the scope of the invention. By nature, this invention is highly adjustable, customizable and adaptable. For example, other attachment mechanisms are utilized instead of magnets for removably attaching components such as the discs and the disc indentations including friction-based locking, hook and loop tape (e.g. VELCRO), etc. These attachment mechanisms are also operable to be utilized in the knee blocks instead of magnets and magnetic discs. Similarly, one or more components described in the present application are operable to be utilized separately from other components of the present invention. As one example, the knee blocks of the present invention are also operable to be utilized separately to provide hip support for users sitting in a cross-legged position. By way of example, use of the knee blocks on the ground or on the floor would cause the angles of the sides of the knee blocks described above in relation to the base of the seat assembly system to be in relation to the ground or the floor instead of the base of the seat system. In another non-limiting example, the knee blocks are operable to be used to provide back support for users to sit with their backs against the knee blocks. The above-mentioned examples are just some of the many configurations that the mentioned components can take on. All modifications and improvements have been deleted herein for the sake of conciseness and readability but are properly within the scope of the present invention.
