I would give this less than 1 star if I could. I was really hopeful about this product and even bought attachment pieces to make it fit the headboard and footboard I have. Unfortunately, the inside of the frame, when it locks together, is less than 60" wide. My slats (which are 60.5 inches) won't even fit. I would have tried another one, but I am in a time crunch before my guests come, so instead, I asked for a return refund (which Wayfair accepted) and I will be ordering a bed/frame set from Wayfair to make sure I have a bed that works!
