This anatomically shaped cushion made of viscoelastic memory foam moulds gently and precisely to the contour of the seating area and increasing the area of contact with the cushion, leading to a better reduction of pressure, improving patient stability, position and comfort.A high density foam insert structures the cushion and acts as a framework that increases or reduces support on certain zones in order to provide optimal sinking of the bony areas into the cushion, transfering pressure to cushion zones with higher-bearing foam. It also prevents forward sliding
