RATED TO 1,000 LB, ANTI-BURST — In independent testing this ball withstood more than 1,000 lb (450 kg) of static load without failing and passed a puncture test under a 265 lb (120 kg) load, deflating slowly instead of bursting. Made from thick, BPA-free, phthalate-free PVC.
FAST PUMP INCLUDED, READY IN MINUTES — The included hand pump inflates the ball in under 10 minutes; two air plugs and a plug remover are in the box, and the secure-seal valve holds air for months without topping up.
TRUE TO SIZE, TAPE MEASURE INCLUDED — Inflates to the full stated diameter; check it with the included tape measure. Choose by height: 55 cm for 4'8"–5'3", 65 cm for 5'4"–5'10", 75 cm for 5'11"–6'4", 85 cm for 6'5" and up. If you are between sizes, or buying a pregnancy or desk ball, choose the larger size. Fill to 80% first, rest 24 hours, then top up.
NON-SLIP, LOW-ODOR SURFACE — A frosted, slip-resistant finish grips floors and mats and stays comfortable against skin, with no strong chemical smell out of the box; wipes clean and leaves no residue on floors.
PREGNANCY, PHYSICAL THERAPY, DESK, AND CORE — Used as a birthing ball for prenatal exercise and labor positioning, in physical therapy for balance and rehabilitation, as an active office-chair alternative for posture, and for core, stability, and stretching workouts at home or in the gym.
