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.
I’m sitting in it right now as we speak, it’s great once you adjust it to your size and preferences! Coming from a cheap racing seat gaming chair that I bought as a teen, this is night and day lol. Not only is it a more mature yet stylish look, the C7 Max ensures I keep my posture up to par throughout my gaming + homework sessions as a grad student in their late twenties!
The arms moving is convenient but they can’t be locked down and if I didn’t wait so long to see if I could just deal with it I would have returned it. Otherwise a fine chair.
There are other chairs for the same price that perform better. The headrest continues to slide down on its own for example, which is very annoying. Additionally, the lumbar support always seems to be in the way and will not move backwards on its own which causes the user to need to push this back with their hand and then sit in the chair. Overall, I would not recommend this chair. I have been trying to use it for 6 months but moved on to something else.
It already isn’t working and won’t lock into the upright position for the seat back. I’m disappointed in the quality of it. If it worked as it was advertised, this chair would be amazing.
