Bests & Worsts Reviews from Amazon

I recently had back surgery to repair a herniated disc (L5, S1) causing severe nerve pain/damage. After about a month I could actually sit up in bed without much pain, but chairs would cause pain almost immediately. I had a piece of foam that I fashioned into a cushion almost the same shape as this, but it didn't work out very well. I searched on Amazon for a cushion, and a bunch just like this one showed up. I chose this one because it just happen to be on sale. I'm very happy I bought it because I don't get anymore of the pain I used to get when not using it. It's a night and day difference. I feel this cushion is a must after a surgery like I had. I wish I had bought it sooner.
