andyvhoAndyvho,
This chair would be a great fit for you. Tomas our buyer for Men's style is using this exact chair now. @tomasv has had nothing but good things to say about the chair including that it is very comfortable and supportive. Tomas is about the same size as you so I am confident this chair will suit you well.
I have also tried a Clutch Series chair and was very impressed with the build quality, attention to detail, as well as the adjustability and the lower lumbar support is the best I have seen yet.
Cheers.
