The same as our Promax cushion, this design has a layer of memory foam on the top for extra comfort.
The Promax cushion is made with a contoured top surface, providing comfort at the key pressure points. There is also a rounded front so the lower thighs are more comfortable, and a slight slope downwards from the front towards the back helps prevent sliding forward and makes it easier to maintain correct posture.
It is provided with a medical grade, breatble, soft stretch, wipe clean and washable cover.
