I have been using this chair daily for over two months now, often for long hours. Here is my impressions. I love the shape of this chair. It fits me (I'm 6'1", 200 lbs). This is the best chair I have ever owned and used! Now I can lean back and take a nap!

I have an older model (~8 years) and one of the wheelbase arms broke off. DXRacer was responsive to my email question and told me which base would work with my model. If you're looking for parts, the links can be found in the FAQ question: "If my chair's warranty has expired and I need to purchase corresponding parts, what should I do?"

This chair is really suitable for me. I have hurt my waist before, so I am very picky about the chair. I did a lot of comparison and comparison before buying and finally chose this one. Comfort, seat support, cushion softness are great, the only downside is that it gets a little hot when you sit for a long time. Overall I'm very pleased with the chair！
