This bed came a little damaged (two of the metal ends of bed rails were bent) but we assembled anyway after straightening them out. The headboard looks great but after assembly, there is about a 1-2 inch gap on each side of the mattress where you can still see the slats and the worse part - there is a almost 4 inch gap at the footboard! This is unacceptable. I'm very disappointed and we have a standard size king mattress (Sealy Beautyrest Recharge). There should not be such a huge gap there. We are contemplating returning it but we haven't decided yet. Maybe we can cover the gap with a huge comforter? Either way, it's way too big for a standard king sized mattress.
