I appreciate that this cushion does not go completely flat like similar items that I have used. I also like that covers more of the back than the normal lower back cushions do and it kind of curves around my lower back. This cushion also has the straps to keep it in place on the chair. I gave it 4 stars because it is not as strong as I need for my lower back pain, it does give some comfort, but I would like more firmness, but I guess this depends on how much pain you have in your lower back. ..More
