Our dynamic air cushion has been designed to give high risk pressure relieving care to bariatric patients who suffer from pressure sores and general discomfort. The cushions have an alternation cycle of ABAB and run using the same pump as our dynamic mattress. The specially designed cover has the zip opening set inboard and underneath, ensuring the cushion is being used the correct side up and also minimizes the risk of contamination. The cover is made from a two way stretch material which conforms to the contours of the body and is vapour permeable, water resistant, fire retardant and soft whilst still being durable.
