What is the average seat depth for a wheelchair, measured to avoid pressure on the popliteal space?

14 inches
16 inches
18 inches
20 inches

The correct answer is: 16 inches

The average seat depth for a wheelchair is typically around 16 inches, which is designed to provide adequate support while preventing pressure on the popliteal space. The popliteal space is the area behind the knee, and if the seat depth is too long, it can cause compression in this area, leading to discomfort and potential circulatory issues. A seat depth of 16 inches generally accommodates a range of users comfortably, allowing enough space between the back of the knee and the front edge of the seat. Furthermore, this measurement also helps ensure proper posture and stability, which are crucial for effective mobility and safety in wheelchair use.
