There is no way to attach the center rail which I guess I will have to bolt down myself at some point. Also the frame appears too big for my mattress and box spring even though  I definitely have a size queen. There is too much space around the box spring. Maybe it's supposed to be like that, I don't know. I was also left with one extra slat then I needed, which I guess isn't so bad. It looks good with the bedding on and I won't be returning it because I have no time. I guess further on down the road I might just purchase a bigger mattress set that fits better. Looks cute though!
