We could not be happier with this buy! We spent months looking at the name brand foam mattresses and even the conventional coil ones, going store to store to lay and roll on to find the perfect one. After reading the MANY positive reviews, we commited to the purchase and are so glad we did! I have a herniated disc in my upper back and need proper neck/spine alignment every night to prevent ongoing pain. I purposely waited several months before rating this so that I could really test out the mattress. From the first night we slept on this bed (and my husband and I are average weight adults) I have not woken up ONCE with a sore back from sleeping. I never believed that would be the case, but I can't stop talking about our bed and the results with our friends and family. We selected th Medium, and it's perfect support without feeling "hard", if you can do that in foam mattress! I'm able to continue sleeping while my husband gets up during the night or when he leaves early for work without being disturbed. The cover is very soft high-quality fabric that is almost nice enough to sleep on without sheets! I've put a mattress cover over it and then our sheets and it's a wonderful night's sleep each night. We also purchased foam contour pillows to aid in the spinal alignment and it's been a wonderful experience. I would HIGHLY recommend this bed for anyone looking for a good quality product that has all of the same specifications as the big ticket/name brands at a fraction of the cost. Why pay thousands of dollars when Overstock gives it to you for less???
