International ClassA47C 021/02AbstractAn automatic bed maker which uses the expansion of inflatable bladder (30) to straighten, align, and tuck-in bed-cover assembly (35). A blanket or insulating layer (29) and top bed sheet (33) are fastened to the bladder (30) forming assembly (35). Assembly (35) is anchored to the bed (38). A blower (55) inflates the bladder (30). A tuck platform (70) drops down to create a tuck opening (73) in the box frame (38B) below the mattress (38A). The tuck protrusion (45A) inflates and enters the tuck opening (73). The tuck opening (73) closes, restraining the left and right side periphery areas of assembly (35).
