FIRM....  not at all what I was expecting from a “cloud” mattress.  Do not buy if you want a softer mattress.  I’ve tried everything I can think of to soften it up some.  I’ve spent an extra $200 just trying to buy a mattress topper to make this bed even useable.  Way too hard.  Would not recommend.  This is my second mattress from this brand.  But after this one, I may have to look elsewhere.  The first one was a green tea cooling mattress and it is ok.  But this one is definitely not something I would buy again.
