Not every stability ball is meant for sitting on all day. Some deflate, some roll away, some are just the wrong size. These are the ones I tested that held up through full workdays.













Sitting on a ball changes your whole desk setup. My monitor was suddenly too low, my wrists hurt differently, and I needed a few adjustments I didn't expect.













Sitting on the ball woke up muscles I forgot I had. After a few weeks I started doing quick exercises during calls, and these made that way more effective.












Some days I just can't do eight straight hours on a ball. These keep the posture benefits going when I need to rotate to something else.













Learned this the hard way. Stability balls slowly lose air and if you don't maintain them, you're basically sitting on a pancake by month three.
