TushGuard MPN-TG0002-NYBL-new Memory Foam Seat Cushion, Large, Black

For adults who spend long stretches sitting, a portable cushion can add targeted support to an office chair, car seat, or airplane seat. The TushGuard uses memory foam and a U-shaped opening designed to reduce pressure around the coccyx and hips. Its handle makes it easy to move between seats, while the removable cover is machine washable.

Size & fit

The large, semicircular cushion measures 18.11" long by 14.17" wide and 3.15" high. Its U-shaped cutout leaves space around the tailbone, and the memory foam is shaped to follow the body's curves. Use it on a chair or seat where you want a portable layer of cushioning, whether you are working at a desk, driving, gaming, or sitting in a wheelchair. The built-in handle helps when moving it from one seat to another.

The black cover has a solid pattern and a zipper for removal before washing. A non-slip rubber bottom is designed to help keep the cushion in position as you shift. That makes it a practical alternative to relying only on fixed chair padding: the same cushion can travel with you and be placed wherever you need it.

Where it shines

The contoured design is intended to support the coccyx and hips while easing pressure associated with extended sitting. Memory foam provides a cushioned surface, and the product is described as retaining its shape after use. Together, these details suit desk sessions and other situations where sitting comfortably for longer is a priority. It can also add height to a seat, a useful feature when you want extra cushioning without changing the chair itself.

The cushion is designed for use in an office chair, car, or airplane, so it can serve at home and on the move. For example, place it on an office chair during a workday, then use the handle to carry it to another seat when needed. Customer feedback often highlights greater comfort during longer sitting and a more bearable experience on chairs without cushioning. Opinions differ on firmness and support, and some buyers report that the cushion can flatten with use, so personal impressions of the feel vary.
