My husband uses This. He weighs 245 pounds and it still fits him. It still helps his back. It truly does separate the desk so you can alleviate some of the pain.

On the way, I can ride in the car for a while and then walk out! Before using it, I'll take some steps, then lock it, then do some step stretching exercises, and then straighten it again.

I purchased this product for back support. It works.

Recently, I had extreme lower back pain, which the doctor told me may be caused by lumbar dislocation. Not too much movement, but even when I sleep, this kind of lumbar support can fix my waist position

Nice product. One of the better back supports made, My husband has lower back pain and this actually has helped his pain tremendously. The inflation of the belt relieves his pain.
