This cushion features a three-layer gel memory foam construction designed to enhance seated comfort and support during extended periods. The top layer uses perforated gel-infused memory foam that conforms to body contours, the middle layer has open channels to improve air movement, and the base provides firm structural support to prevent compression. At four inches thick, it suits wheelchairs, office chairs, car seats, and recliners. Its shape encourages pelvic alignment and reduces pressure on the tailbone, hips, and lower back. A breathable, removable cover wicks moisture and is machine washable. The bottom surface includes a full rubberized non-slip coating to maintain position across various seat types. It weighs little and includes a built-in handle for easy transport. The 18 by 16 in. dimensions offer broad compatibility without requiring custom fitting.
