When I selected this headboard I did not realize it was sized for full and queen.  My mattress is full, so the headboard is larger and the holes for attaching a queen bed frame are exposed when using this for a full mattress.  Much worse,  the pre-drilled holes for attaching the full-size frame are spaced too wide, so my frame did not attach without having to drill new holes.    I am very disappointed with the quality of this product.  I should've known - you pay cheap, you get cheap!
