This bed was very easy to assemble. I was able to do it alone, but I might have gotten it done a little bit FASTER if I'd had a second person. The instructions were so easy to follow! I laid everything out first and followed the diagram. The mattress fit perfectly. It hasn't been slept on yet so I may write another review in a few months. I really wanted the brown, but it was out of stock. But the bed is beautiful!!
