Once together bottom horizontal board not very secure. Although it doesn't affect the integrity of the bed. Also only comes with screws to attach to the bed frame they are selling that matches the headboard. If attaching to metal bed frame you need to get your own screws. I called customer service and found that one out. The person that helped me also gave me the wrong amount and size screws I needed both in width and length, So FYI - you need  4 (not 2) 3" long and 1/4 in width  bolts along with 8 washers and 4 nuts.
