Help me unwind after work!

This chair is great! After a stressful, both mentally and physically, day at work, it helps me relax and remove my knots. Love the heated option! I am also on the shorter side, but it works for me compared to other massage chairs I’ve used before. Shipping came on time and assembly was quite simple.

Nice chair great heater

I love the zero gravity and Bluetooth features. It’s on wheels making it easier to move. The heater works great! Nice chair and price. We ordered during the time there was all sorts of shipping issues in the world causing a pretty big delay. The company was great about working with us and keeping us updated.
