This mattress has been used as a weekend guest bed and slept in a total of 4 nights so far no complaints from the guests who are slightly above average weight , though I have noticed it leaves the in print on the surface of the matress so I have to spi  it round to straighten it out every weekend , it's mid firmness , personally I think firmer would be better , as stated above guests haven't complained when asked how they slept.  I'm used to memory foam so personally I wouldn't have this as my main mattress.
