5mm mousepad vs 2–3mm mousepad: 5mm wins for bumpy desks and wrist rests

5mm smooths out desk imperfections and keeps a wrist rest from feeling like you’re hovering over a cliff, while 2–3mm pads can’t hide dents or seams. Thicker than 5mm (like 8mm) feels spongy and lets your wrist rest sink in weird. 5mm is the sweet spot.
