Didn't work for me
I was excited to try the product. I've been dealing with a still back for years. But when I set it up on the first level and laid on it, the plastic "bridge" just buckled. It didn't break, it didn't snap; it just plopped back down to the base. In case you are wondering, I do not exceed the weigh limit for the product. When I moved the bridge up to the second level, it held ok, but the pain was too much. I think you need to progressively stretch your back in the stages over time, and with a defective first level, I just couldn't do that.
