Like many of the other reviews I read, I was in desperate need of a new mattress. For the last year, I have experienced shoulder and hip pain. I was very excited to receive my new mattress topper and could hardly wait the suggested 24-hour "airing out" period. In fact, I only waited about 12 hours and was not bothered by the slight remaining chemical smell. While I was waiting, I laundered the fiber topper and it held up very well. I covered the memory foam with the topper and added my own waterproof mattress cover over that ,and sheets. I was relieved that my current sheets fit well over all the new products on my bed. I was impressed the very first night I slept on my "new" mattress. After the second night, my shoulder and hip pain went away. Over a month later, I am still impressed with this mattress topper and very happy that I purchased it.
