This is a Moulded cushion made of viscoelastic gel and HR-foam that features High-reticulated viscoelastic polyurethane gel, which avoids gel migration thus preventing all punching of the support. The addition of a high-resilience foam base enables the cushion to adapt better to bony protuberances, thus providing a larger contact surface, therefore more effective distribution of pressures. Moreover, it improves patient comfort and stability Because the two layers of the material are moulded together (? stuck), they are completely bonded, thus eliminating all risks of separating over time.
