We spent a lot of time pondering this purchase, first time ever purchasing a mattress with testing first. 
We're so glad we hit the purchase button...
This is a very comfortable mattress and at a fantastic price, it's a bit of a "head-scratcher" at first when you look at the size of the delivered package, but rest assured it does deliver...do not attempt to open the package until its in its final resting place!...and give it a full 24+ hours to fully "deploy".
We love it, most every night we make comment on how comfortable it is...
