Set the relative height of your chair & desk so that you type & mouse with straight wrists (not flexed up or down) Reduce wrist pronation (inward twisting) by using a split/tented keyboard and vertical mouse or trackball Ensure monitors are placed high enough so you can see them without sagging your neck forward (this is a big drawback with laptops) All the rest of it - standing desks, exotic chair designs, desk treadmills, mechanical keyswitches, keyboard trays, gas spring monitor arms - are basically a huge waste of time & money if you can’t nail these three basic things. For a monitor stand I bought one of the indistinguishable $25-$35ish metal desk clamp monitor stands; the only real requirement I had was it being tall enough to hold the monitors at eye level.
