I have lived with back pain for a long time. I heard of memory foam and wanted to try it. but the price always kept me away from it. After many days of sleeping 9-10 hours of day just to get that rested feeling. and still waking up with pain, rolling out of bed different ways just to try and reduce the pain of getting up. Well Now that is over!!!! I am not saying I wake up everyday pain free. The work load from the day before does reflect a little bit. BUT I feel great I have been sleeping 6-8 hours and waking up rested and ready for the day, Pretty bad when your excited to go to bed. All in all. If your reading this and are just not sure if it does what it says it does. I will Say oh yeah its advertisement is spot on. I am amazed It is well worth the price I paid for it. and PS it cost less than a standard mattress. 10" mattress is as thick as a standard mattress. dont hesitate buy it and start sleeping good again. I have no negative feedback on this product at all.
