Negative Positive
Title: Ouch!
Review: I bought this to put on the chair we use when we sit at our home computer. Neither my wife nor I have back problems. My thought, however, was "what could a little extra cushioning hurt?". The answer is "my back". Maybe this provides relief if you have back pain or have had an injury. Our experience was that it forced us to sit in an unnatural way and thus CREATED back pain. Just like a lot of items, it really might depend on the individual as to whether it is helpful.
