The invention relates to a surgical support (20) having a base (22) which is ergonomically shaped to support a part of a patients anatomy and a removable cover (24) which has an inner surface (30) and an outer surface (32) and which is adapted to fit over the base with its inner surface toward the base. The cover carries a cushioning pad (34) which preferably comprises memory foam and is secured to the outer surface of the cover and positioned to be interposed between the patient and the base in use. The relatively bulky base can be used multiple times. The cover and its cushioning pad are easily replaced.
