Great chair with nice features for the price. Husband has lower back issues, and this has helps. Good relaxation tool. You can adjust specific areas by going into the tools functions and manually changing. The foot massage does a great job and really gets in there. Easy to assemble. Small gripes are the touch keys on the remote itself do not light up, only the screen. The rollers are at the base of your skull and do not start again for about 8-10 inches, so they do not massage the neck to about 4 inches below the trapezoidal  upper shoulder muscle groups. Per instructions it does need to be unplugged when not in use, and glitches if you dont. So we just plugged into an easily accessible power strip and turn off the strip power when not using or need to reset it by turning it offon again. Easy fix. Overall we love the chair and its been money very well spent.
