I’m 5’10” and medium build. This chair feels like it was designed to fit me. It’s very comfortable but I’m already doubting that the materials will be durable over a long time. The material on the seat near the front is already wrinkled making me believe it’s stretching after only a few weeks of use. Despite this I’m very impressed with how much this chair has improved my overall quality of life. I tend to be sitting 8-10 hours a day on this chair and no longer feel any pain that I was getting from my old office chair. Time will tell on the durability.
Bought this chair in April and been using it for 3 months for probably 8+ hours a day M-F. It was pretty easy to assemble. At first I did not attach the headrest thinking it would push my head forward too much but eventually I did and I'm glad I di. After a few days of getting used to the chair in general my body figured out how to sit in it correctly and enjoy all the ergonomic support features. Great value for the price and definitely worth it to not have to jerry-rig my existing chair options into an ergo-friendly sit. The mesh gives nice support and allows for air flow to keep things cool. Highly recommend.
