The Alerta Gel Cushion is a gel cushion containing polyurethane SensaGel which acts as a layer of artificial fat, to provide effective comfort, care and pressure redistribution for users in hospital, nursing and home environments. It can slide and move laterally to effectively reduce shear forces and is guaranteed not to harden over time, neither leak nor dry if accidentally punctured. The PU cover is fire resistant classified M1, waterproof and vapour permeable. It can be laundered at 90oC. The cushion can be cleaned with a damp cloth.
