Chair arrived intact and sooner than I expected.  I ordered the medium driftwood with arms.  The seat is big enough to sit on and the arms don't squeeze you in.  The shift from low to high and vice versa is strong.  My 16 y/o grandson put the chair together in an hour; I would say you need 2 people to assemble and the casters were the hardest for me to insert that's why I asked my grandson for help. I have only had for a few days but the chair feels sturdy and safe.  Great price too!
