Comfortable and exactly what I was expecting. Assembly instructions were very easy and clear. Did not install the arm rests so that the chair could easily slide under my computer desk without lowering the seat bottom. This chair replaced the 10-year old office chair that lost pressure in the lifting cylinder. We transferred the roller-blade style wheels we had on the old chair that protected our hardwood floors to the new chair and we're back in business!
My wife has found this chair without the arms installed to be just right for her computer desk. The only problem is that she doesn't weigh enough to make the air piston depress but I took care of that for her.
