The back did not fit in the grooves at the bottom,  they were cut too small. I had the bottom and sides connected  and all unpacked when I found this out, I put the top on with the screw and forced the top to line up as well as I could, but the bottom still didn't line up in the back. It is all together but isn't lined up like it should be, doors are a little off. Guess I should have sent it back, just didn't want to deal with the hassle of shipping and packing it again. It is a nice sturdy piece if the back was cut correctly.
