So happy we bought "Chair Vader"
Yes. Money well spent. It hurts like hell at first but that's only because my muscles were so tight. It works your feet, your butt, it has a heater, it has programs or you can customize where it rubs. I wish it could get my neck a little better but overall it's amazing. I have  been  using it for almost two weeks and I'm noticing an improvement in my posture. Can't beat the price and the free shipping.
