I bought this not knowing really what to expect. It came in a oblong box, and I thought for sure that this was never going to be a ca.king box. But after opening I discovered that it is all metal and real easy to assemble by following the simple instructions. I think it's better than the old wooden box springs, and if I decide to get rid of it someday down the road, it'll disassemble just as easily for storage or transporting.
