The new UPEASY Power Seat can easily transform any firm surface armchair into a lift chair, and has a 10 foot power cord included. The device will not work on a padded or cushioned surface. It operates easily using the power lever located on the left-hand side of the cushion. When you're ready to sit, simply push down on the power lever, and lift the power lever when you're ready to get up again. When you are ready to stand this assistive device will help support but will not fully lift you into the standing position. UPEASY Power Seat also has the added benefit of being portable. Weighing only 12 lb (5.4 kg), this power cushion has a built-in carry handle, which makes it easy to take from place to place.
