I had a lift chair but was not comfortable as it was too big..I purchased an air lift chair in small and it’s a delight to sit in it ..very comfortable and my back pain has gone as this chair has a good back support,, it’s great to relax and put the leg rest up and adjust the back rest and complete heaven..great chair as the air padding is so soft to sit in. Best thing I have purchased for my aches and pains..
