Pretty impressed with how quickly this mattress expanded after I cut it out of its sealed packaging. I'm talking 30 seconds or less it was almost fully puffed, with barely any noticeable odors being released.

As for the mattress itself, it is on the firmer side, but I find it quite comfortable with my comforter set and mattress pad I already had for a queen bed. It also doesn't move much and I think it would be great for those who are constantly woken up by their partner as it seems to really dull the sensation of movement. The mattress itself comes with a bladed opener and a 10 yr warranty insert, both of which were a nice touch. I think it's a fine mattress and will work wonderfully for my guest bedroom.
