Since we bought this king-sized bed in February, I've been needing a nightstand for really no other purpose than to charge my iPhone over night. I finally got around to solving this today. Its a 6-inch lacquer box with a velcro cord storage underneath. Total cost: $11. It took longer to take these photos than it did to install.
