You could put your fattest counsin on these babies and they wouldn't break. Easy to build, everything that you needed was included. And I love the way they look. I accidentally matched my new bed frame to them. The lights are sticky LED light strands. They aren't sticky enough. But I dont care I didnt buy it for the lights.
