This portable and economical lifting seat is perfect for those who need help to stand. It activates automatically as the user stands, lifting up to 70% of their weight up to 220 lbs. It is fully self-powered and does not require electricity instead using a hydro-pneumatic gas spring. The patented LeveLift Technology ensures gentle and safe lift without pushing you forward. Weighing just 9 lbs., it has a built-in carry handle and works on most armchairs or sofas. The 100% polyester cover is fully washable, and the polyurethane foam cushion is easy to care for.
