The AliLite Prone Positioning Set includes essential components for pressure redistribution and nerve protection for vulnerable areas during prone procedures. The AliLite Prone Headrest offloads pressure and maintains neutral position. The AliLite Prone Positioning Set includes a prone headrest, knee support, prone positioner, heel pads and armboard pads. The AliLite Precontoured Positioners reduce pressure by distributing weight over a larger surface area. Up to 50% lighter than comparable gel-only products, AliLite gel-foam positioners are easier to handle, impervious to fluids, naturally bacteriostatic and feature a stable, nonskid base. AliLite gel is made of dry viscoelastic polymers.
