This is the portable assisted lift cushion that helps one easily rise out of a chair, sofa, or other seat. The push of a button slowly and gently raises the seat to minimize strain on the legs, knees, and back as an individual moves from sitting to standing. The unit wraps around a chair back and inflates/deflates using an easy-to-use two button remote. The portable unit folds into a compact carrying case that easily fits in a closet or car trunk. Supports up to 400 lbs. Charges via AC; a full charge provides up to seven days of power. 63" L x 17 3/4" W x 15-20" D (adjustable seat). (6 lbs.)
