A mattress designed to prevent bedsores is made from an open foamed plastic box enclosing pillows filled with stuffing in a cushion cavity. This construction is enclosed in a zippered mattress cover, which may be waterproof. The pillows can be separate or joined together to form a compartmentalized pillow cushion. The pillow cushion can be made from a pillow bag stuffed with textile fiber or foamed plastic particles and divided into compartments by seams. Separately formed pillows may be left loose within the cushion cavity, or detachably joined together. The mattres can have pillows of different density stuffing or sizes the seams being transverse and compartmentalizing the pillow bag; and reclosable closure means in at least one of the seams for easily reopening and reclosing it, whereby the stuffing in the compartment accessed by the closure means may be adjusted.
