Bed with mattress assembly having one or more internal plates
View Patent ↗A bed is provided that includes a foundation configured to be positioned on an underlying floor and a mattress assembly supported on and secured to the foundation. The mattress assembly includes a base layer and a body supporting portion. One or more internal plates are interposed between the base layer and the body supporting portion of the mattress assembly and are maintained at a fixed height relative to the underlying floor. The foundation and the mattress assembly are moveable between at least a first predetermined height and a second predetermined height relative to the underlying floor. As a result of the movement of the foundation and the mattress assembly between the first predetermined height and the second predetermined height, the one or more internal plates apply pressure to and compress the body supporting portion of the mattress assembly, thus increasing the firmness of the body supporting portion.
1. A bed, comprising:
a foundation configured to be positioned on an underlying floor;
a mattress assembly supported on and secured to the foundation, the mattress assembly including a base layer and a body supporting portion; and
one or more internal plates interposed between the base layer and the body supporting portion of the mattress assembly, the one or more internal plates being supported on one or more legs extending through the base layer and the foundation and that maintain the one or more internal plates at a fixed height relative to the underlying floor;
wherein the foundation and the mattress assembly are moveable between at least a first predetermined height and a second predetermined height relative to the underlying floor, and wherein, as a result of the movement of the foundation and the mattress assembly between the first predetermined height and the second predetermined height, the one or more internal plates apply pressure to and compress the body supporting portion of the mattress assembly.
2. The bed of claim 1 , wherein the body supporting portion is comprised of a flexible foam.
3. The bed of claim 2 , wherein the flexible foam is a visco-elastic foam.
4. The bed of claim 1 , wherein the base layer is comprised of a high-resilience foam.
5. The bed of claim 4 , wherein the high-resilience foam is a high-resilience polyurethane foam.
6. The bed of claim 1 , wherein the mattress assembly further includes an upper comfort layer that is positioned atop the body supporting portion.
7. The bed of claim 6 , wherein the upper comfort layer is comprised of a flexible foam.
8. The bed of claim 7 , wherein the flexible foam is a visco-elastic foam.
9. The bed of claim 1 , wherein the bed has only one internal plate that is substantially coextensive with a lower surface of the body supporting portion of the mattress assembly.
10. The bed of claim 1 , wherein the bed has multiple internal plates.
11. The bed of claim 10 , wherein the bed has three internal plates, a first plate in an area that would accommodate the head of a user, a second plate in an area that would accommodate the hips of the user, and a third plate in an area that would accommodate the feet of the user.
12. The bed of claim 1 , and further comprising multiple adjustable legs extending from a lower surface of the foundation for facilitating movement of the foundation and the mattress assembly between the first predetermined, height and the second predetermined height relative to the underlying floor.
