I got this mattress because we are finishing an upstairs bedroom.  We found it easier to carry a memory foam mattress up the stairs.   I already have two downstairs from other manufacturers that I am happy with.  We followed the directions and waited 72 hours to test the mattress.  It is way too soft for my comfort.  If you like soft mattresses, this is the one for you.  I am now going to have to bring this one downstairs and swap it with the one in the guest bedroom.  Other, it is fine.
