I was worried based on reviews that this would be hard to assemble and that there were problems with it.  But, it turns out that b/c it is solid wood and metal, warping occurs if you screw in things super tight on on end and it'll seem like certain bars don't align or are too short.  My tip is put in the screw just enough to get everything to line up and then tighten.  If you tighten on end it'll cause warping and it'll seem like the other end is not manufactured to line up with the holes.  It is very solid and well made.  Very happy with this purchase.
