"29.5 INCH PURPLE PREGNANCY BALL: Our purple pregnancy ball is perfect for prenatal exercises and relieving pain or discomfort during pregnancy and labor. Made of durable, burst-resistant material, the gym ball has a weight capacity of 550 lbs and a 29.5 inch diameter when inflated. Ideal size for women up to 6'2". "BABY-FRIENDLY BURST-RESISTANT MATERIAL: The pregnancy ball is made of durable, burst-resistant PVC. If punctured, it slowly deflates instead of bursting, making it safe to use during pregnancy. PVC material is free of phthalates, carcinogens, and other harmful substances for your baby during pregnancy. "COMFORTABLE NON-SLIP SURFACE: Anti-slip lines around the fitness ball prevent it from slipping out from under you while using it to relieve pressure on your pelvis, lower back, and spine during pregnancy or improve comfort during labor. Non-slip feature is also essential when using the gym ball for birth preparation. "PUMP & MEASURING TAPE FOR EASY INFLATION: The pregnancy gym ball comes with a hand pump and measuring tape for easy inflation to the correct size. To use the ball effectively, we recommend inflating it to 80% of the recommended size and letting it sit for 24 hours before fully inflating. A spare plug and removal tool are included with our gym ball & accessories. "USE OF BIRTH BALL: Sitting on a chair or sofa can be uncomfortable during pregnancy. A pregnancy gym ball distributes your weight to reduce pressure on your back and pelvis. During labor, it can relieve discomfort and open your pelvis and hips to prepare for childbirth. The gym ball is also great for postpartum exercises to aid in recovery."
