Which seating option is primarily used when there is no seated deformity?

• A. Bevel front edge of seat
• B. Planar seat
• C. Sling seat
• D. Custom molded seat

Answer: (B)

When there’s no seated deformity, you want a simple, flat surface that provides even support without forcing a particular pelvis or spinal shape. A planar seat is exactly that: a flat, non-contoured surface that distributes pressure evenly under the sit bones and allows neutral alignment. It doesn’t attempt to mold to a deformity, which isn’t present, and it provides a stable base for any cushions or adjustments you might add. Beveling the front edge is a modification aimed at easing transfers or knee clearance rather than improving posture for a normal pelvis, so it isn’t the primary choice when no deformity exists. A sling seat relies on fabric that sags and distributes weight poorly, leading to unstable support and pressure issues over time. A custom molded seat is designed to fit and compensate for specific deformities, which isn’t needed here.
