We hung three of these over our king size bed and the fourth on another nearby wall in the same room. They are very pretty but 4 just looked like too much over the bed. They are METAL. I totally missed that in the description but was pleasantly surprised how pretty they look despite me not connecting the dots properly. They are very light weight and we only hung them with a single nail instead of trying to line up the keyhole hangers in  each corner. They make the room without being too busy.
