Viola II Alternating Pressure Relief Cushion System
While pressure relief mattresses provide adequate protection from pressure sores for bed-bound, pressure relief cushions are required to maintain that pressure relief while they are seated in a chair. The Viola II Alternating Pressure Relief Cushion System offers continuous pressure relief for patients at very high risk of pressure sore development, featuring alternating air controlled by a simple and intuitive control panel. With both alternating and static modes, along with a a dial to control pressure levels, it offers highly customisable support.
Please Note: the Viola II Alternating Pressure Relief Cushion System requires connection to a mains power supply. If you are looking for a mobile pressure relief cushion, we recommend the Alerta Mobile Alternating Air Cushion System. You can also view our full range of pressure-relieving wheelchair cushions.

- The power unit can be placed on the floor underneath the chair. Ensure that the power cable is routed in such a manner so that it can't be twisted, trapped, crushed or stressed.
- To connect the cushion to the power unit, plug the cable into a suitable electrical socket and switch it "ON" using mains power switch found at the side of the power unit. The power will start the inflation and the "Normal Pressure" indicator will flash.
