My husband has a rise and recliner chair supplied by the council. He is always wiggling his bottom and used to slide onto the floor. At home, daily, I have the chair semi reclined, he is semi-sitting up, but, his feet are elevated. If I have to pop to the shop, I recline him fully, and he is fine, usually falls asleep. My husband is doubly incontinent. I place washable waterproof sheets across the chair, this keeps the chair dry and clean. CH could use disposable ones.
