Tony, here's my 'working from home' setup if this gives you any ideas. The three laptops (there's sometimes a fourth!!!) are the work devices with the two uppermost 24" monitors repeaters/extenders for whichever laptops I connect them to. The ultrawide is attached to my personal computer (An Intel [now Asus] NUC).
The keyboard is the Logitech G915 which is superb and the mouse a Logitech MX Master 2S.
My chair is an Ergohuman Plus.
