SERENESITZ™ is an ergonomic seat cushion built around one idea: stop putting your whole body weight on your tailbone. The W-shaped cutout lifts your coccyx clear of the seat while high-density memory foam spreads the load across your hips and thighs. A breathable 4D cover keeps you cool, a slip-resistant base keeps it put, and the universal size fits office chairs, car seats, sofas, and airplane seats.
