Bathmaster's Sonaris Bath Lift is a very user-friendly lift - just pop in the battery and sit the unit in your tub, and it's ready for use! This bath lift is designed to be taken apart and reassembled quickly and simply, which makes it perfect for travel use. The Sonaris Bath lift is operated entirely via a hand control which utilizes smart technology that prevents the user from lowering the seat if the battery is too low to lift someone out of the tub. The battery lasts for about 18 uses of the lift before requiring a recharge, and you'll always know when it's getting low because the Sonaris is equipped with a low-battery warning beeper and indicator light. The reclining backrest can be lowered as far as 40 degrees for a fuller bathing experience. This Bathmaster lift is covered by a 5-year warranty on the frame and a 2-year warranty on the hand control and recharger.
