Works as described. Purchased for post-op lumbar surgery. (M, 5'6" 205lbs)  Really makes getting up easy, safer and much less painful. The chair feet do slide a lot on the wood floors so I need to put some no-slip pads or something under them.  Purchased the extended warranty and I will guess it will be needed.  It's hard to be sure, but the cover feels a bit thin to me. Overall a good purchase.
