Abstract
A device for varying the firmness of a body supporting foundation, such as a box spring of a bed assembly or the like, including a vertically movable platform provided with a plurality of spaced resilient cushion members that may be selectively positioned at different distances from the upper support surface of the foundation for modifying the degree of deflection of the support surface without affecting the inherent resiliency of the individual springs.
Claims9
A variable firmness control device for a foundation defined in part by an upper support surface and an internal support structure for providing resiliency to the upper support surface, which device comprises:
- (a) a platform for attachment to the underside of the foundation below the internal support structure;
- (b) a plurality of spaced resilient members carried by the platform;
- (c) means for moving the platform for simultaneously postioning the resilient members between portions of the internal support structure and at a desired distance from the upper support surface whereby the degree of deflection of the upper support surface is determined by the position of the resilient members independent of the internal support structure.
