I have had this Inversion Table for several years now, and It works great for me! I have had a bad back for years and nothing the doctor did for me really worked. They always wanted to do surgery and I didn't want to go that route, so when I heard about the Teeter Inversion Table, I figured it couldn't hurt to try it. I am so glad I did. It gives me relief in no time and keeps me out of pain, or less pain, for days.
It works by tipping you upside down to stretch out your back and help put things back in place. You can very easily control the amount of tilt you want from slightly to all the way upside down. It is easy for me to right myself back up by just raising my arms. It folds up flat so it can be stored in a closet or hung on a wall, or I can even slide it under my bed.
There are adjustments for height on the machine, so it can be used for any size person. I am 6'6" and have no trouble using the machine even with my height.
If you want an alternative to traditional medicine for your back, I would recommend you try this before having surgery.
