Retailer ratings4.2 · 236 ratingsOne of these is on the shelf, waiting its turn in the inspection queue. That price is the most it will list at, never more. Anything we find comes off it. An inspection can also find a unit we will not sell, and then this one never goes on sale.

About this item
This seat cushion uses high-density slow-rebound memory foam shaped with a dual-hole ventilation cutout and a U-shaped tailbone notch, intended to ease pressure on the coccyx, sciatic nerve, hips, and hamstrings. The curved edge design is meant to lift the thighs slightly to reduce leg fatigue, while the cutouts allow airflow to reduce heat buildup during long periods of sitting.
The cover is made of a cotton-polyester blend with a zipper for removal, and the base has a non-slip grip to keep the cushion in place on chairs or car seats. Side handles allow the cushion to be carried between locations such as an office, car, or home.
It is sized X-Large at roughly 16.5 by 16.5 inches, intended to fit a range of office chairs, car seats, wheelchairs, and gaming chairs.
