I looked for an affordable and stylish upholstered King headboard for months. I found this one on a Wayfair daily sale so it was under $200 at the time. It took me 10 minutes to assemble and I did not attach it to my frame, it's just resting on the floor and the bed is pushing it against the wall. We've had it for over a month now and it is perfect. The grey is dark and tweed material like, and the nailheads are about the size of quarters. It's very cool and it adds amazing style to our room.  It looks so high end for such a reasonable price.
