I have had this chair for approx 7 months now. I enjoy the seat heater and it has held up well. My only complaint is that it loosens itself in the tensioner, leaving you feeling like you are sitting on a pendulum, bobbing around. This has caused me some back pain. It is fixable. We just realized that you can tighten it yourself. It also creaks and makes noise, so I have to sit very still when on zoom meetings.
