This was a easy assemble and great bed after we put it together. I have a king size mattress and I order the Eastern King Size but my bed did not fill the platform. The instructions told us to put the small boards under the beams in the middle and when we laid on the bed the boards started to come undone and our mattress sank in. We had to get up in the middle of the night and put the small board on top of the beams. Overall I love my platform.
