This was NOT easy to put together considering the bottom part of the desk was in basically 3 pieces...top and sides (drawers..well yea)..but the problem was that the sides did not line up with the top.  Side B fit all day long....Side A well that appeared to either be not cut properly or IF I COULD JUST GET A RUBBER MALLET... I CAN MAKE IT FIT feeling.
The side of A would not fit, so it was either sand, shave edge down to fit or get rubber mallet....I got rubber mallet all is well.  Just as an FYI the top does NOT screw or has a way to secure the hutch part to the bottom of the desk..just sayin'   Roseanne
