Many other reviewers stated it took about 3 hours to put the unit together - I am 62, an overweight, arthritic woman and I put it together in under 2 hours.  Instructions are simple to follow, all the holes lined up perfectly all the parts were there and marked.  It looks very nice in my space.  The 4 stars are because this doesn't look like a high end piece of furniture - but it is very nice.
