This mattress so far is amazing.  I got it a couple weeks ago but was waiting for my bed to arrive before I opened it and so far I have slept amazing the last 3 days.  Considering I had a traditional mattress previously and it was about 10 years old and I was sleeping in a even older one for the last 2 weeks, this mattress is like sleeping on a cloud.  Wish I would've purchased one sooner.
