    My back loves this mattress
    Another quality product from Sealy. It delivers all the results it says in the product description. I have a bad back and this mattress relieves a lot of the pain I have. I read all the reviews and that is what helped me decide on this mattress. Make sure you do your research before commiting to buying. Good luck.
