Heavy duty solidly built chair! A gift for my husband, which meant I was the one who had to put it together. Not a great deal of assembly required - I didn’t time myself exactly - but from the time it arrived at our front door within 45 minutes it was sitting in front of my husband’s desk. A really gorgeous office chair and both of us have found it to be very comfortable. Also delivery was quite a number of days early from the original time frame which is just a marvelous plus!
