Quality: True Memory Foam! Not just those falsely advertised memory foam. Cushion cover are cotton which is good as it gives room for your back to breathe.
Usage: I sit in front of my PC for more than 10 hours a day hence i sustained a mild back pain recently that is why i needed lumbar support. i purchased one from a local chemist which is more expensive than this one but it is not a true memory foam despite the claim. But this one is really good. for the first two days of use, effect is really noticeable.
