This looks great.  My 14 year old son and I put together.  Took about 6 hours and we used a drill which made it go faster.  All the parts were there and directions were good.  Very sturdy, but like others have said, best to build it in the room that is its destination.  Hutch is nice but we elected not to put the backing on it.  Made the room to dark and we thought the backing looked a little cheap.  Without the back on it, it does sag in the middle.  We attached a small wood "shelf" painted the same color as the wall right in the top middle of the hutch, which the hutch then "rests" on to keep it from sagging in the middle.  My son loves it.  We put a desk blotter down to protect the wood.
