I had recently bought the same mattress in the twin size for one of our day beds. I was so impressed with the comfort, that I immediately bought the queen size, also in firm. The price for this mattress was too good to be true. When it arrived, it was quickly placed on my queen size bed. I have never known such comfort and had spent thousands of dollars on other mattresses that did not give the the quality of rest that this mattress has provided. If anyone suffers from back aches, I highly recommend this mattress. It will be the last one you will have to buy. Again, thanks for offering such a wonderful product.
