Bought this headboard for a full size bed in a guest room.  It looks terrific and was easy to assemble although it came with no instructions.  Since it fits either a full or queen bed it had metal plates to make the adjustment, but a diagram would have helped. Note if you have a full bed, the frame will extend outward at the bottom where it attaches to the plates. If you don't mind that, you will love this headboard.
Much nicer than more expensive headboards I've seen in stores!
