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.

Manufactured wrong

Double check the mounting holes BEFORE you assemble! I got the whole thing put together, and then realized the left side bracket was incorrectly manufactured- the mounting hole is on the front of the unit instead of the back, so I can’t actually hang it on the wall. The assembly was easy, though.
