I'm using a long back mesh executive chair, the cheap kind. It gets smelly quite fast and the foam on the seat cushion is so thin that you can feel the hardwood or plastic underneath it already, it also has a flimsy head rest that can be adjusted left or right and even loosened. The issue is that it can unscrew itself by just moving it side by side and it's annoying. You can tilt it by forcing your body to push backwards and with the spring underneath it, it would easily pull it back, but it's adjustable just in case you want it to be loose or slightly lowered.
This is probably my 4th chair out there because most of the chairs we had were cheap and flimsy one. It's either the cushion or the whole chair falls apart.
Do I hate it? I just hate that it doesn't really last long, primarily still better than a monobloc chair or the dining chair but it doesn't really last long.
