Abstract
A cushion comprising an orthotic base which has a flexible body of sufficient strength to support a user while conforming to the buttocks and legs of the user and pillars on the bottom of the base to support the same and being of desired height and positioning to position the user in a desired position. The disclosure shows a preferred composite cushion comprising the orthotic base; a foam top on the base with a T-shaped cutout at the rear to accommodate an air cell pad; a balance foam underpad of smaller front to rear measurement than the base and movable from the front to the rear of the base to incline the user in a desired front to rear positioning and from left to right to position the user in a left to right direction; and a cover enclosing the base, the foam top, the air cell pad and the underpad. Removable support members are attached to the pillars beneath the orthotic base at predetermined locations to shape the top surface when a load is applied. Removable shapes also can be located on the top surface of the base to position the user in desired positions. Openings are provided through the base to facilitate moisture removal from and air circulation to the user. A method of measuring the conformity of the cushion to the shape of the user using a memory foam pad is shown.
