An adjustable seat that can be selectively adjusted to provide pressure relief for the back of the thighs and buttocks. The seat has two adjustable seat sections placed under the user's thighs. In one embodiment, the seat includes the main support body comprising a flat, horizontally aligned lower surface, a perpendicularly aligned, wide rear surface, a vertically aligned narrow front edge, a diagonally aligned upper support surface, and two equal vertically aligned side members. Disposed over the diagonally aligned support surface are two parallel, elastic wedge-shaped seat sections or two inflatable wedge-shaped seat sections. Each elastic or inflatable wedge-shaped seat section is complementary in shape and may create a flat seating surface on the seat accessory when the two wedge-shaped seat sections are longitudinally aligned over the diagonally aligned support surface. Each wedge-shaped seat section covers approximately one-half the diagonally aligned support surface. When one wedge-shaped seat section is removed from the main support body to accommodate the hip replacement patient's affected hip, which should not exceed 70° in flexion, the obtuse angle of the main support body supports the hip's approximate 70° angle of flexion. An optional attachment means is used to selectively connect each elastic wedge-shaped seat section to the main support body. With inflatable wedge seat sections, an air pump and control switch are also provided.
