Claims
- 1. A mattress with layer combinations, comprising one or more hermetically sealed chambers, a first of said chambers having an airtight outer covering enclosing all other chambers, said first chamber having at least one core of self-inflating polyurethane foam located therein, and having at least one core of coil springs located therein, and having at least one valve fitted in a wall of said first chamber serving as a means to evacuate air.
- 2. The mattress combination of claim 1, including one additional chamber containing a self-inflating foam core which is hermetically sealed.
- 3. The mattress combination of claim 2, including two additional chambers within the first chamber, wherein a self-inflating foam core is placed in the first additional chamber and a core of coil spring in the second additional chamber, and are both hermetically sealed from each other and from said first chamber.
- 4. The mattress combination of claim 2, including one or more valves fitted to each chamber, constituting means for selectively evacuating air from each of said chambers using a vacuum pump.
- 5. The mattress combination of claim 3, including one or more valves fitted to each chamber, constituting means for selectively evacuating air from each of said chambers using a vacuum pump.
- 6. The mattress combination of claim 1, including two additional chambers within the first chamber, wherein self-inflating foam cores are placed in each of the two additional chambers, said additional chambers are individually hermetically sealed from each other and from said first chamber.
- 7. The mattress combination of claim 6, including a coil spring core placed between the two additional chambers in the manner of a sandwich.
- 8. The mattress combination of claim 7, including one or more protective layers placed one above and one below said coil spring core.
- 9. The mattress combination of claim 7, wherein the coil spring core is fully enclosed in a further additional chamber, hermetically sealed from the other chambers, thereby constituting a combination of four chambers.
- 10. The mattress combination of claim 1, wherein one or more valves fitted to the first chamber only penetrate through their own wall.
- 11. The mattress combination of claim 2, wherein one or more valves penetrate through the wall of the outer covering and through their own second chamber wall communicating with the interior of the foam core chamber.
- 12. The mattress combination of claim 3, wherein one or more valves penetrate through the wall of the outer covering and through their own third chamber covering communicating with the interior of the coil spring core chamber.
- 13. The mattress combination of claim 1, wherein the core of self-inflating foam is subdivided into at least three hermetically sealed sections and, forming with the coil spring core a four part whole mattress, each part having its own chamber.
- 14. The mattress combination of claim 13, wherein each of the subdivided sections have at least one valve fitted to their own chamber wall to communicate with the outside air.
- 15. The mattress combination of claim 1, wherein the foam density and IFD values which are factory preset in their original configurations can be selectively modulated through the removal of air.
- 16. The mattress combination of claim 1, including one or more air permeable distancing elements that separate the valves fitted to the chamber walls from any adjacent materials.
- 17. The mattress combination of claim 16, wherein said air permeable distancing elements are communicably attached to the valves.
- 18. The mattress combination of claim 1, wherein an evacuation of some air from the foam core chamber, with said valve closed results in the core's slow recovery after depression, and alters the tension of the coil spring core.
- 19. The mattress combination of claim 1, wherein said self-inflating foam core, as it is expanding and increasing in volume, constitutes a means to compress any other chamber directly adjacent to it.
- 20. The mattress combination of claim 1, wherein said self-inflating foam core, when reduced in volume by removing some air, constitutes a means to allow any other adjacent chamber to expand.
- 21. The mattress combination of claim 1, wherein said coil spring core, as it is expanding and increasing in volume, constitutes a means to compress any other chamber directly adjacent to it.
- 22. The mattress combination of claim 1, wherein said coil spring core, when reduced in volume by removing some air, constitutes a means to allow any other adjacent chamber to expand
- 23. The mattress combination of claim 1, wherein each chamber can be emptied of air with a vacuum pump to facilitate transport and storage.
- 24. The mattress combination of claim 1, wherein a plurality of chambers and cores are placed in a longitudinal or lateral orientation each of which can be individually and selectively modulated as to comfort.
