Seat Cushions

A seat cushion is a functional padded accessory designed to be placed on a seating surface. Its primary purpose is to enhance sitting comfort and alleviate physical discomfort caused by prolonged sitting through physical support and pressure redistribution. The fundamental working principle involves the use of elastic materials (such as memory foam, gel, or high-density foam) that deform to evenly distribute pressure points across the hips, tailbone, and lower back. This is often combined with specific structural designs (like U-shaped cutouts, hollow rings, or contoured shapes) to avoid localized pressure on sensitive nerve areas (e.g., the sciatic nerve). These products are widely used in various daily scenarios, including office environments to support long hours of desk work, car driver seats to enhance driving comfort, wheelchairs to assist in relieving persistent pressure points, and home leisure or gaming chairs to optimize the experience. The primary target user groups encompass office workers, long-distance drivers, wheelchair users, students, and gaming enthusiasts—essentially anyone who spends extended periods seated. Based on different functional focuses and material compositions, seat cushions can be categorized into key variants such as basic memory foam models, gel-infused cooling models, ring-shaped cushions (e.g., Donut Pillows) targeted for tailbone pain relief, and washable portable models.
