It's well-made and there's nothing to complain about. Just in case there's anything that's not clear about the assembly, please check the following. For the sleeper, check the top and bottom, and then attach the first one to the pole, then lower it slightly and you'll hear a click, so attach the second one. You'll understand when you try it. The two types of poles are the H type with the adjuster at the bottom (the one that comes at the bottom). The flat side is the top side of the shelf. The metal fittings on the four corners are trapezoidal, so you should be able to tell. Also, it's better to have a hammer and a towel if you can.
