So I moved into a bungalow and my queen size mattress frame would not fit up the stairs. So I bought this item to get my mattress off the floor. It made it up the stairs with no problem. It feels sturdy when sleeping on it. I was a little worried that my boyfriend is 350+ and it may not support us both. But there have  not been any problems. It comes with a clasp in the middle in order to keep the two pieces from coming apart.   It was easy to assemble and my boyfriend did it in a matter of minutes.
