Our unique dual-foam construction adds a layer of comfort not found in single-foam cushions. The foundation is a high-density foam for stability. To that, we add a formed, medium-density insert layer. Combined, they distribute body weight to eliminate pressure points and spinal strain. Whether driving for long periods of time or sitting at an office chair throughout the work day, you will appreciate the difference. Use it in your car, home or office. The removable, washable polyester cover has a mesh center for breathability. Available in Black. Measures 18" W (front), 14" W (back), 16" deep. Approx. 1-1/2" high.
