Which seating component is described as not intended for long-term use and requires no postural support?

• A. Planar seat
• B. Custom molded seat
• C. Removable seat insert
• D. Sling seat

Answer: (D)

The seating component described is one that provides little to no built-in postural support and is used only temporarily. A sling seat is a fabric surface that stretches under the user without contour, padding, or adjustment to hold the pelvis or trunk in a stable position. Because it offers no intrinsic support for alignment and pressure distribution, it is not intended for long-term use. It’s typically used for quick positioning or during initial assessment rather than ongoing seating.

In contrast, a planar seat is a flat surface that can be used with cushions or supports for longer-term use, a custom molded seat provides a contoured shape to support posture, and a removable seat insert adds targeted postural control and pressure management. Thus, the sling seat best matches the description.
