The EWin Flash XL office gaming chair has a weight capacity of 500 pounds, and it has steel frame construction with an aluminum base with 5 caster wheels. Not only will the Flash XL handle your weight, but handle your height as well. I am very tall, and I can actually make use of the head rest built into the Flash XL gaming chair. I do not even need to raise the chair at all for my legs to be comfortable and feet sit planted flat on the floor. EWin has made a great looking gaming chair, but how well does it function, and how comfortable is it for hours of gaming?
