This was a little tricky to assemble by myself because in order to get the height as shown in the photo, it's actually 2 rails stacked on each corner, not 1 as you would expect. The assembly is also different from what I'm used to, so it came apart a few times until I got the hang of it. The beams also took a heavier pounding to get them to fit tightly, but it seems pretty sturdy and looks nice. The shelves are heavy even though they look like particle board.
