I hastily turned the gaming corner into my home office in March. It hasn't evolved a huge amount since then. Luckily a big screen and "sex worker rated webcam" work for both uses. The rudder pedals double as comfy footrests.
I sourced "useful piece of wood" from my stash in the garage to fashion a handy headset stand on the radiator for my softphone headset. The big set of cans lurking behind the laptop screen don't do work stuff very well.
The PC is used for Teamviewer sessions with servers/users and other automata.
The laptop is work issued and used for anything that requires VPN.
I don't have a cat, but my dog is very soft.
