I bought this product for my mother who is 62 yrs old suffering from lower back pain and had undergone a spinal surgery where L4-L5 was removed. Although, this surgery took place more than 20 yrs ago,she still has problem sitting on absolutely hard or absolutely soft surface , can’t sit for long no. of hours at a stretch. Comfort memory foam cushion has alleviated her discomfort to such an extent that she uses this product while sitting on a couch, chair ,in the car and also while travelling in a plane. The cushion is with her at almost all times. That states to what extent this product can be use full for people who face discomfort while sitting for few minutes or few hours. Its 100% value for money !!! ..More
