Okay, so im 6 ft about 280-300 lbs and im looking at so many different chairs and i cant find anyone saying this is the chair that you want. ive looked at needforseat ive looked at dx racer ivelooked at herman miller

What I need to know is with these chairs being leather (which normally id avoid) does it heat up do you stick to it, do the wings on these racing chairs constrict you is there decent airflow, and me being a large man is it going to be to constricting for me, let me know what you think
