Not a joke, whatever chair you buy, budget $20 or $25 for a professional grade stability ball for "sitting breaks". It's good for posture, core, etc. and helps

Not a joke, whatever chair you buy, budget $20 or $25 for a professional grade stability ball for "sitting breaks". It's good for posture, core, etc. and helps one to stretch out a bit. I thought it was weird until I tried it, and now I always keep one next to my desk.
