The Invacare Uplift Seat Assist turns any armchair into an automatic lifting seat. This self-powered lifting cushion assists you gently up and down from an armchair or sofa. As you sit down on the cushion, you are gently eased into a seated position. The lifting piston activates automatically as you shift forward and begin to stand, providing a stable lift up from the chair or sofa. Coated in memory foam, the cushion adjusts to your weight, shape, and temperature to provide ultimate comfort. This cushion is extremely portable, as it includes a built-in carrying handle. The waterproof, fire-retardant cover is removable and machine washable.
