Abstract
Abstract 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.

Claim 1
Independent Claim
124 words
A mattress comprising: an open box of firm but resilient material having an upward facing cushion cavity extending substantially the entire length of said box; a plurality of adjacent individual pillows containing stuffing and disposed in said cushion cavity, each of said pillows having at least two inclined upper surfaces, said inclined surfaces of adjacent pillows defining a space between them; fastener flaps extending outwardly from each pillow, the flaps of adjacent pillows overlapping one another to form a detachable connection, whereby the body of a user resting on the mattress lies over an alternating series of supporting pillows and spaces without support, and the width of the space between adjacent pillows can be changed by adjusting the extent to which the flaps overlap.
Claim 2
Dependent Claim
