In a substantially U-shaped cushion (1) for medical purposes, said U-shape defines a central channel (4) wherein the average width of the channel is significantly less than the diameter of a generally circular cut-out area (3) in which the channel terminates, thereby to define opposed projection portions (8) at the conjunction of the channel and the cut-out area. The cushion may be pneumatic or fluid filled but is preferably formed of a laminate of an upper softer and a lower harder layer of closed cell foam. The cushion may be overlaid by a towelling cover. This arrangement allows long stay patients to sit comfortably without obturation of the blood or lymphatic systems. <IMAGE> |
