You should be careful buying a gamer chair - they’re often made for aesthetics and not for long-term comfort or back support, and can be kind of bad value for money because of that. Office mesh chairs are designed to be sat in for a long time whereas gamer ones are based on racing car seats which are designed for drivers to be in for an hour. Not to say they’re never worth buying but make sure it’s properly adjustable and the such for your build before buying :)
