The Comfort Company M2 Zero Elevation Wheelchair Cushion With Comfort-Tek Cover is constructed with a dual-density foam, a molded foam base, and Quadra3D Gel pack. It provides exceptional pressure relief and comfortable, cushioned seating for wheelchair users. Specific design elements like tapered leg adductors increase in width near the back of the cushion to give support to the greater trochanter. The deep lateral and medial leg contours promote postural alignment while the Coccyx relief cutout eliminates pressure on the tailbone and spine.
