Title: great ball high quality
Review: purchased this approx 2 wks ago. I'm 6' 3" and 240 lbs. and I've sat at my desk using this ball for up to 12 hrs. a day to strengthen my back. Very sturdy, dependable and good quality. Would highly recommend for anyone. be sure to purchase right size depending on your height. I believe they range from 45 cm (for 5 ft. or so) up to 85 cm for 6' 4" and up but double check to make sure. Also, would recommend using a motorized pump to inflate this ball vs. hand or foot due to amt. of air and pressure needed it would take all day long otherwise.
