I didn’t realize when we ordered it that it was a twin bed on top, even when ordering the “full” option - you can tell from photos, but I wasn’t paying attention. Relatively easy to put together with clear instructions. Some of the metal beams are long, so having a second pair of hands is ideal. Some of the seams in the metalwork are a little rough, and it can wobble a bit with someone moving around in the top bunk, but overall feels solid.
