Ordered this chair for my dad after spinal surgery. Initially put it together and the chair does not stop vibrating once it is plugged in. The remote does not work on our chair. We try to turn off the vibration or turn on ANY of the other functions and it does not work. Have to unplug the chair if you want it to stop vibrating  altogether. The other functions are not connected or something within the chair is broken shorted out. They sent is a new remote seeing if that would solve the problem, but the remote still does not light up and won’t make the functions of the chair work. Pretty disappointed that it can only be used unplugged and as a plain ole chair without any features. Wasted some good money here.
