Due to a forced move, I have had to sleep on a different bed that is the old fashioned mattress and box springs. Even though I am in great physical shape, I began to wake up each morning stiff and with back twinges. The difference, I realized, was the missing memory foam mattress bed and topper so with nothing to lose - except back pain - I returned to Great Offer Stock where I had purchased the bed I used to sleep on, and through research settled on this mattress topper. Received it three days ago. I would call mine FORGOTTEN MEMORY foam due to waking up on the very first morning without a single back problem . Thinking it might have been a fluke that first morning, I am ecstatic to say every morning since has brought the same result. This is a proven product. YAY - happy back, happy girl!!!
