BODY RHYTHM Upgrade Multifunctional Workout Chair for Core & Abdominal Strength Training, Back Stretcher for Back Stretching, Back Pain Relief, and Inversion Tables for Inversion Therapy.

I own a Teeter X3 table with the lumbar insert. I love it and will continue to use it, but THIS THING is something else. I'm 78 and my posture has suffered from years sitting at a desk in front of a computer. This thing stretches your total spine and hip flexors like nothing else I've ever used. Assembly is simple but the tools provided are lacking. Also there's movement in the headrest and the unit itself when flexing back that takes a little getting used to. However despite that the unit feels solid and easily supports my weight (165 lb) and I'm sure a lot more. I'm glad I bought it which is the highest compliment I can pay anything I spend my money on :)

This is definitely easy to use. Works good for stretching your back.

Does not feel safe while using very unstable and sux to try to return. Not worth it

Item was small but big enough for what it is used for ...I love it

Got the product set up exactly the way it described in the booklet. I did the exercises as described as well. I did the one in the pic where you arch back and put the leg up to help the back. It pitched me over backwards and I slammed down on my head and neck really hard onto the floor. I was actually choking myself from the weight of my body suspended in mid-air. My chiropractor said he’s had patients that have bought this machine and it’s too heavy and not balanced properly and will do that. Just be careful if you have to buy this. I sent the machine back. It’s too dangerous for me.
