Hi Mary. That is a custom bed frame and headboard. The bedframe does not actually attach to the headboard. It just pushed up against the wall mounted headboards. The corner headboard is actually two separate headboards that butt together in the corner. Our upholster made them, but they are basically wood backs with some Dacron then faux leather upholstered over it. We added decorative nail heads around the edges to "spice it up". They have flush mount cleats on the back that screw directly to the walls. We cut the ends short of the actual width and length of the bed to make it look unique. This headboard extends up above the top of the mattress by 24". ***you could also buy two headboards and butt them up together too. ie one king headboard (for the long side) and a full or queen headboard for the short size depending on the size of your mattress.
