The main cushion component of the Comfort Company Vicair Liberty X is designed with a completely sealed PVC liner containing a front and rear chamber. It holds Comfort Cells coated in a silicone lubricant giving them a low-moving, yet fluid-like motion when conforming to the patient. The liner also has an air valve that, when opened, allows all the excess air to escape after a patient sits on it. Once the air has escaped and the cushion has taken on the fitted shape of the patient, the air valve can be closed and the cushion will retain its shape. A foam base is installed separately under the main cushion component to give additional femoral support and Trochanter loading to the main cushion. The base foam has a separate cover and waterproof zipper for superior incontinence protection and infection control.
