Most uncomfortable chair on the planet
I have owned a secret lab and razer chair and used each for years. I was looking for something with more back support and found this chair on several review pages. I have used it for less than a week and am already experiencing extreme back pain in my lower and upper back. The chair does not have enough cushion and so your spine sinks down to the hard frame both in the lumber area and the upper back area where that frame portion curves back in. It almost seems intentional once I felt it, because it is aimed right at your back. There does not seem to be a purpose for it ether, its just cosmetic, but its part of the frame so there is no way to adjust it. I have tried several different adjustments and nothing prevents it from stabbing you in the shoulders.

ALMOST perfect for tall people
I am 6’4, 240lbs and this chair is ALMOST perfect. I have owned and tried a lot of chairs looking for the perfect combo based on my height and comfort, and this chair comes closer than most. I love the 4d arm rests, back support, and the different ways you can adjust the headrest. The only thing I do not like about this chair is that if you are sitting with your back straight and butt towards the back there is a gap between the back of the seat that your butt/tailbone sort of hang over. Most chairs have a seat adjustment where you can slide the seat forward or backwards, or at least multiple screw holes underneath so you can move the seat, however, unless I am missing something this one does not. If I could slide the seat back a few inches so the backrest was closer to the seat, this would be the perfect chair.

Thank you for your feedback! The C7 Max does have a seat depth adjustment feature. It&s the adjustment lever located at the back left of the seat cushion. Pull up the adjustment lever and push your hips outward to adjust the seat depth. Lift up the adjustment lever with your hips off the seat, the seat will automatically reset. Total travel distance of 1.96". Let us know if you need any assistance!
