Mangar Archimedes Bath Lift is a convenient bath lift chair that is comfortable, easy to install, and easy to operate. The chair requires no electric cables and is entirely battery-powered. This unique bath lift chair fits far enough back in the tub to leave plenty of legroom for the individual to sit comfortably. The chair is stabilized at the bottom of the tub with four quick-release suckers. The flaps on the sides of the lift bend when they come in contact with any obstructions to avoid causing any damage while lowering into the tub. These flaps have an anti-pinch design that keeps the skin from being caught in the flaps while the lift is in motion. This bath lift chair is also designed not to lower a person into the tub if there's not enough battery power to pull them back up.

The hand control that is used to operate the lift is fully waterproof. This bath lift chair is capable of lowering within three inches of the bottom of the tub. It is easy to install and remove, making it a convenient option for a shared bathroom.

Vitality Medical carries many bathroom aids and lifts, including bariatric commodes, transfer benches, the Body Up Transfer Lift, and Invacare hydraulic patient lifts.
