timo0 - Hi all. I want to tell you that in the Mattress Firm store this mattress was just wonderful. After researching mattress firm reviews on https://mattress-firm.pissedconsumer.com/review.html , we were convinced that we had finally found a sub-$600 mattress that met all our needs. This mattress we bought from the Mattress Firm was a gift for our son. He loves it and said he slept like a baby since getting this mattress. Also, it was taller than his old mattress, which is great because our son is 6'3".
