I thought that the concept was great, a foldable box spring to be more manageable by a single 5'3 woman. I was able to get it out of the box and unfolded pretty easily. HOWEVER there is a major design flaw. When you open up the box spring, there isn't a way to lock out the ends, so the head and foot portions are dipping down everytime weight is put on them. I know that the boards of my bed frame are spaced a little off, but there should be a way to lock the box spring in place to keep from collapsing when you trying to lay down.

Update: When laying on it, it doesnt fold down. It works wonderfully.
