Pro tip: I swapped my desk chair for a yoga ball and my back pain vanished in 3 weeks
I spent 2 years in a cheap mesh chair from Office Depot and my lower back was killing me every day by 3pm. A coworker said to try a 65cm yoga ball instead, so I grabbed one for $25 on Amazon. Within the first week I could feel my core working just to stay upright, and after about 3 weeks the daily ache was basically gone. Has anyone else made this switch and noticed a real difference in how you sit all day?
