AliGel™ Leg and Foot Patient Positioner Products set a new industry standard in pressure-relieving properties. All AliGel Gel Patient Positioners offer a unique gel formula that mimics fatty tissue and moves with the patient to reduce shear and help prevent pressure injuries. Additionally, AliGel positioners absorb shock and stretch to retain their shape better than less dense patient positioners. AliGel is made of 100% dry viscoelastic polymers.
