It seems like it is becoming flat when I lie over it. I have spent so much time and money on my back so decided to give it a chance. I think it is expensive.

The device does as advertised, providing support to the lower back when sleeping. It is hard to get used to when you first begin using it, but it does work. My only reservation is that it tends to slip around when it is being worn. I don't know how this problem could be corrected, and it is minor when compared to the benefits.

This device didn't work for me. My problem is when I sleep flat on my back I wake up with lower back pain. I was attempting to support by back with the night roll. That is doesn't work for me doesn't mean it won't work for your problem.

Like many other back-pain sufferers, I've dropped a lot of coin on all sorts of medicines, gadgets, etc. and I decided to take a chance on this due to the back pain I get each morning upon awakening. The product itself is ok and does what it says, but just know that this is one of those things that will take some getting used to. Sleeping with something wrapped around your waist all night is not easy to stick with, but I can say that I notice some relief when I first lay down because it keeps my back from sagging down into the mattress. Like a lot of other things - it is hit or miss. I will keep it, but I'm not sure I'll always use it.

I think this item does what intended to a degree; however, it does seem to flatten out more in the back than I would like.
