I got the mattress delivered and it arrived in rolled-up state. I put them in bed and waited until is fully deployed. This lasted a few hours, however, I was surprised really positively. The mattress also does not smell unpleasant or otherwise has any defects. Sleeping on it's a dream, super comfortable and adapts relatively well to the body. It's the best mattress I have ever slept on. I do not want to think away me. Thus, a full five stars earned.
