Kensington - Ergonomic Memory Foam Seat Cushion, High Density Foam, Removable Washable Cover, Carry Strap, K55805WW - Black

The Kensington Ergonomic Memory Foam Seat Cushion is a supportive seat rest built around a high-density memory foam core, intended for office workers, students, and commuters who spend long periods in a chair that offers little padding of its own. The cushion measures 17.5 inches wide by 15.5 inches deep by 2.75 inches thick and weighs about 3 pounds, a footprint that covers a standard task chair seat pan while staying light enough to carry between a desk and a car. Its most distinctive quality is the way the memory foam responds to body heat and weight, settling into the contours of the sitter so support is distributed across the whole seat instead of pressing against the tailbone. Kensington states the shape promotes healthy posture, improves circulation, and provides tailbone and lower back support during extended seated work. An anti-slip silicone friction grip covers the underside so the cushion holds position on mesh, leather, and fabric seating rather than sliding forward as the user leans and shifts. The outer cover is removable for cleaning, which keeps the cushion serviceable in shared offices, classrooms, and home workspaces. Kensington reports the construction has been durability tested beyond 80,000 uses, so the foam is expected to retain its rebound across years of daily seating. A built-in carrying strap lets the cushion travel to a conference room, a stadium seat, or a rental car without a separate bag. The cushion is finished in black to match most seating, and each unit ships with the cushion, its removable cover, and documentation.
