PL300 is made of a fluid gel and a polyurethane foam base, contained in a PVC sack. The fluidity of the gel layer enables an optimal distribution of the body weight, decreasing the pressure on the capillaries and preventing eventual occlusions. The polyurethane foam base allows the body to sink into the cushion, but at the same time ensures an adequate support in order to avoid the effect of bottom out and guarantees the stability of the seat. The cover is antibacterial, waterproof, breathable and bielastic. This property allows a considerable reduction of the friction between the skin and the cushion.PL300 is supplied with an anti-slip bottom to assure a safe and stable anchorage to the chair.
