I ordered this product while it was on sale in November 2011 and it arrived quickly. It was easy to put in place. I feel relief from long-term stress in my back and look forward to getting to bed. My posture has improved and I no longer feel like a back massage is needed. It is definitely better to sleep on something soft versus hard. It saved me the cost of buying a new box spring and mattress. I intend to purchase another one (queen size)! If you're hesitant...be confident that you will be glad to have bought one.
