I had one of these I had bought from Penney's and didn't think I needed it anymore so I got rid of it. Now I am on the hunt for another one and thank goodness I found it. I suffer from GERD and have had a terrible issue with it again here lately. I know this product stinks but the best way to use it is to place it between your mattress and box springs. It gives you an incline to sleep on to help with heartburn.
