ABSTRACT:
A therapeutic sling seat comprising a flexible material which is non-uniform in stiffness providing maximum contact surface area with the body of a person seated in the seat by spreading the forces away from high pressure areas using multiaxis tension forces. The seat material in tension adapts to the contour of the posterior of the seated person. By controlling the pressures on the ischial tuberosities, physical problems such as ulcers can be avoided.
