I am a 68 yr old woman and except for putting the top on I did the whole desk by myself ( it took 2 people to lift the top on and 1 person with good eye site to line up the pegs). It took me a lot longer than 8 hrs. but I was in no hurry.  I was shorted several screws but the manufacturer sent them when notified that I needed them  The desk is beautiful!  Looks way more expensive than what it cost.  I just love it!
