This works
This thing really does wonders. I threw my back out so bad that I could barely walk into the ER in my own, and the doctors helped me lay down and gave me one of these to use for 10 minutes and then asked me to try to stand up out of bed and to my shock and awe, I was able to get up out of bed unassisted. They told me to buy one of these and I’ve never regretted it.  It also comes apart in the middle so that you can take it in a suitcase etc. but it is also still very sturdy.  I would say though that if you’re over 250lbs you may want to search for one that is wider or has a bigger distance between the ball and the other side of the curve so that it’ll fit more comfortably around you without being tight.
