The new UPEASY Power Seat can easily transform any firm surface armchair (or stable seating surface) into a lift chair.  It provides 100% lift for users weighing up to 300 lb (136 kg), and has a 10 foot power cord included.  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.  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.
