Any chance you might take a selfie of you sitting in your chair? Just want a better understanding of how you properly sit.I got myself a new office chair last year, after the nylon wheel base blew out. I hunted down my new one based on weight tolerance (got one for 250kg), with a solid metal base. I'm also 5ft tall , so recommend getting yourself a footstool if you don't already have one. It stops my feet from hovering over the floor and my butt from slipping out of the chair too.
