The VivaLift! Tranquil 2 PLR-935 by Pride is a true infinite position power lift recliner that lays all the way flat. The backrest and the footrest move independently, so you can stop anywhere between upright and level, including a position that lifts your feet above your heart.
The headrest and the lumbar are both powered, so the support lands where your neck and lower back actually need it, and the remote holds two positions you can return to with one button. A lithium battery keeps the chair moving in a power cut, and there is a USB charger port in the hand control. No heat and no massage on this model; the Radiance and the Ultra are the ones for that.
