This is a very nice office chair. It is comfortable (if you are skinny is well-cushioned and rolls great on my chair mat. Had to dock it 1 star for being too narrow for me.
"Bonded Leather" is an advertising copy person's catchphrase to induce one's purchase based on the fact the surface (seating) is genuine. I noticed the chair does not "breathe" as leather should thus making one's torso warm and uncomfortable after extended usage. The material is nothing more than "leather" shreds interspersed with plastic bonding material. The chair is being returned.
This is a really nice chair and a very comfortable. The sale price combined with an additional discount from Staples made this quite reasonably priced. Delivery was made on the specified date. Assembly was not difficult. Although I was concerned about buying the chair without being able to try it I could not be more pleased with the purchase. Highly recommend.
