Low back pain has improved since sleeping on this mattress past 30 days. Numbness in hands that occured when sleeping on my side has gone away too. At age 64, 130 lbs., it is the right combination of squishy & firm support for me. Husband thinks it's okay too. Not the quality of name brand memory foam but not the price either. Took 3 weeks for corners to plump up but customer support was supportive :-)
