I really like the chair and it works almost perfect. The vibration part does not do any good at all tho for me, I may have it hooked up wrong , not sure but directions for chair are not real good. If u have a bad back as I do, then it hurts to use the chair too much , u really have to discipline yourself, with wanting to use it. Also the chair is more so for a Biggggggggggg tall person so , smaller people do not reach the right levels of the massage parts. But overall, the chair is a good one and the online price is totally better than the Store price.
