Bought this chair for my 81 year old Dad.  He LOVES IT!! It was simple to put together and he can't get enough of the heat and massage funtions. With the massage feature he's been able to go about his daily functions with a fraction of routine back discomfort without any topical or medicinal additions.  He barely needs the lift function due to the benefits the massage is giving him but when he does need it its handy and simple for him to use.
