Oh my o my o my. Of the three things I ordered this one was the one I was the most excited about. The way it came packaged, bundled up like a sleeping bag, I wasn't to sure if I ordered the right size. I had to get it up the stairs to the second level, so if that is you as well it takes two people to get it to your bed. Be careful when you take off all the plastic wrap, when air gets to this mattress it expands very rapidly so make sure you open the package after you get it on the bed. But I tell you what folks I had a real bad back ache from work and from putting all of these three great pieces together from wayfair. But after I got into this great mattress my muscle worries were put to rest, I woke up relieved of my back issues and one of the most dreamful sleep I have had for a long time, and I am usually a light sleeper, but not on this mattress. A must buy for every one.
