I too experienced this chair at a Home Show. It was honestly the best massage I ever got from a chair… the show price as about $3000… maybe I can afford it for retirement. Amazon’s description of this chair’s technology does not do the chair justice: Not only could the IR sensors really figure out exactly where my muscles were to adjust the roller width but the 3D technology is also able to push the rollers into your muscles instead of just rolling over them. Air bags in the foot massage unit constantly presses your feet down onto a small set of tiny rolling pin tractor treads… I was never one for foot massages, but wow. The thing also scrunches you up then the air bags grab you by the ankles and the shoulders while the chair unfolds out straight to really strech your body. I want to find this chair again to test the neck massage capabilities.
