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.
