I have not had such a wonderful sleep in over 15 yrs! I have had back pain for many years that MD's and Chiropractors could not help. This product did everything it claimed to and more. I couldn't wait to use it and even though I used it the day I got it I had no problems with the " new smell". The size issue mentioned in other reviews was not valad as this queen size fit perfectly on my "oversized" queen bed
