Exercise Ball Chairs

Choose a ball diameter based on your height: about 55 cm for people up to ~5'5" (165 cm), 65 cm for ~5'6"–5'11" (167–180 cm), and 75 cm for taller users; when seated your hips should be slightly higher than your knees for proper posture

They can promote active sitting and core engagement but are not a medical device; use them for periods rather than all-day, combine with regular posture breaks, and consult a healthcare professional if you have chronic back pain or balance issues

Look for anti-burst/anti-slip materials, a stable base or removable ring for desktop stability, weight capacity rating, included pump and repair plug, and size options that match your height

Prices commonly range from budget options under $50 to higher-end models over $80; cost varies with build quality, base/frame features, branded safety testing, and included accessories like pumps or lumbar supports

Inflate to the manufacturer’s recommended diameter using the included pump and check firmness by seating and adjusting; keep it clean with mild soap and water, avoid sharp objects, and periodically check for leaks or wear

Children and people with balance or mobility limitations should only use them under supervision and after checking weight capacity and stability; a base-supported model is safer than a free ball for those users

Review the stated weight capacity, anti-burst certification or testing information, and any manufacturer warranty period; longer warranties and clear safety testing details generally indicate greater manufacturer confidence in durability
