I'm sharing an overview of my desk, where I spend most of my days working (I'm a freelance graphic designer) and gaming when I have a moment.

The big recent change is my new chair. I ditched my old IKEA chair, which was uncomfortable during long days, for a much more complete model from Autonomous: adjustments in all directions, better support, and a mesh seat that breathes much better than what I had before. With my back problems, it really makes a difference—I end my days feeling much less tense.
I had my doubts about the mesh at first, but after several days, it's been a pleasant surprise. If anyone has any advice on maintenance or feedback on the durability of the seat, I'm all ears (my previous chair quickly accumulated stains that were impossible to remove).
The armrests are also more useful than I expected: I don't use them much for work, but for playing on the console, in a more relaxed position, they're really comfortable.

For the rest: Mac Mini M4, LG 32UD89-W monitor, XP-Pen tablet, iPad Air, MX Keys/MX Master, Switch OLED, Xbox Series X, Analogue Pocket, Bose + Sony WH-1000XM3. A simple and clean setup, designed for work... and extending the day with a little gaming session.

Please feel free to suggest changes to improve my setup. Or if you have questions about specific elements.
