Nice adjustability comfortable and quite a solid chair. The mesh back is comfortable durable and breathable. My only negative is that I wish the seat had just a little more padding but I'm a little pickier about that than most people would be.
I bought this for use at my sewing machine - not office use exactly but one that can mean hours of sitting leaning over. This chair fits my needs: provides good adjustable back support and occasionally leaning my elbows on the armrests relieves muscle stress in my shoulders. An additional kudos for the rapid delivery when it wasn’t in stock at the store I visited.
