I ordered this for my husband.  We just switched to from a king size foam memory mattress to two twin Xl hybrid mattresses.  Set up was easy, it was delivered rolled up tight in plastic and in a box.  The mattress inflated as soon as it was unrolled.  My husband has been using it for about a week now and he likes it a lot.  Th only negative is that this mattress is sold as medium-firm and it is a bit on the plushsofter side than he thought it was going to be.
