This Trideer Extra Thick Yoga & Exercise Ball ($26) is equipped with a matte, thick, nonslip material to resist slipping when hands get sweaty, and it is also burst-resistant for safety. It is designed with a honeycomb structure that makes it deflate slowly in the event it is punctured, so you don't have to worry that it might pop out from under you.
