摘要：
Height adjustable mattress assemblies generally include a foundation frame including side frame members and transverse frame members attached at respective ends by a corner bracket to define a generally rectangular shape. A deck is supported by the foundation frame and adjustable support legs are coupled to each one of the corner brackets. Each of the adjustable support legs includes an outer tubular member fastened to an interior facing portion of the corner bracket and a differential driven linear actuator including an extendible portion. The assemblies further include a single or dual actuator assembly mechanically engaged with the differential driven linear actuators in each one of the adjustable support legs to extend or retract the extendible portion so as to change an elevation of the foundation frame relative to ground upon actuation thereof. Also disclosed are processes for adjusting a height of a mattress assembly.
