I have to start with the delivery. I didn't receive a bed in a box. By the time it finally arrived, it was a bed in the plastic. That was really disappointing. There was holes punctured in the plastic and i could put my finger in it and feel the mattress. I did consider returning it, but decided to keep it. Secondly, it's super heavy! At least the king size is. My advice, put it where you want it to go while still in the plastic. We took the plastic off in our living room and had to push it upstairs to our bedroom. Big mistake... it took 3 of us to push it upstairs with great difficulty. Thirdly, the bed is awesome. I feel like I'm at a hotel. It's really firm and soft, which is what I wanted. It's really big and thick and fills up the entire space of the bed frame. There will not be any pillows falling behind the bed! I really love this mattress, hopefully it last!
