EquaGel is made of a dry-polymer gel that is rubbery to the touch. This gel forms columns in the EquaGel cushion and when a user sits on the cushion, the columns buckle into the hollow area between the walls for comfort and support. Air channels between the gel walls promote air flow. This, along with the breathable cover, optimises the skin microclimate. EquaGel cushions are maintenance-free, do not require set up and are flexible for use on wheelchairs seats. The Equagel Adjustable Protector Cushion has the following features: Ideal for advanced cushioning needs Includes two pelvic gel inserts to increase therapeutic support under pelvis Thick or thin inserts for customisable cushioning needs Fluid resistant, flame retardant, vapour permeable cover 63.5 mm high (without inserts), with 44.5mm of buckling gel under pressure points Specifications Overall Height: 6.4cm Available Sizes Product Code Width Depth SMCE2204 40cm 40cm SMCE2206 40cm 46cm SMCE2208 46cm 40cm SMCE2210 46cm 46cm SMCE2212 51cm 40cm SMCE2214 51cm 46cm SMCE2216 56cm 40cm SMCE2218 56cm 46cm
