I was very hesitant to buy a headboard online since you can't feel what you're purchasing in advance, but after doing some research, Wayfair has the best prices so I went for it. I got a King Sized Pewter headboard and it's absolutely perfect. I love the the dark gray color, the velvet isn't too velvity looking and it was very easy to put together. 

I will say with a King headboard, it was definitely a two person job attaching the headboard to the bed frame. Minimal tools are necessary and the directions are short since there isn't much to it as far as putting together. So happy about my purchase!
