Abstract: Mattress assemblies including static and adjustable mattress foundations generally include a foundation frame including side frame members and transverse frame members attached at respective ends by a corner bracket at each of the respective ends to define a generally rectangular shape. An adjustable support leg coupled to each one of the corner brackets for automatically elevating the foundation frame relative to ground. The adjustable support leg can include an outer tubular member fastened to an interior facing portion of the corner bracket including an end cap, wherein the end cap includes an aperture. A motorized linear actuator can be coupled to the outer tubular member, which can include a motor and an extendible portion coupled to the motor. The extendible portion is configured to selectively retract from and extend through the end cap to change the elevation of the foundation frame relative to ground.

Abstract: Adjustable mattress foundations generally include a mattress support surface including a head and back section hingedly connected to an intermediate seat section at one end and a leg and foot section hingedly connected to the intermediate seat section at another end. The intermediate seat section includes spaced apart upper and lower panels, wherein the lower panel is hingedly connected to the head and back section and slideably engaged with side frame members of the foundation, and wherein the upper panel is stationary and hingedly connected to the leg and foot section. A linear actuator is operatively coupled to a linkage assembly to independently effect inclination or declination of the head and back section relative to the intermediate seat section and is further operative to effect an increase or decrease in a length of the intermediate seat section by movement of the lower panel relative to the upper panel.
