STOROMO's 45cm exercise ball is an extra-thick, non-slip yoga and birthing ball designed to support pregnancy, balance training, Pilates and everyday sitting with high burst-resistance.
Compact at 45cm (17.7in) and finished in a soft purple, this stability ball combines durable eco-friendly PVC with a textured surface for grip and comes with a fast pump plus an exercise tutorial. It’s meant to be a versatile tool for prenatal comfort, gentle core work and active sitting at home or in the studio. Follow the included inflation guidance (inflate, let sit 2–3 days, then top up) to reach the correct size and strength.
The STOROMO ball gives a stable, cushioned seat for pelvic rocking, upright positioning and gentle movement that many pregnant people find more comfortable than a chair. It supports pelvic mobility and can be used during contractions for upright labor positions without sliding, thanks to its textured, non-slip finish.
Yes — the ball is suitable for core training, stretching, balance drills, Pilates and light rehabilitation exercises. Its high load tolerance provides stable resistance for seated or supine exercises while the non-slip texture keeps movement controlled.
The ball is constructed from eco-friendly PVC and is engineered to resist bursting under normal use; manufacturer testing indicates high tensile strength up to 2000 lbs when properly inflated. For best longevity avoid dragging the ball across rough wood or painted surfaces which can abrade the material.
The 45cm (17.7in) diameter is ideal for shorter individuals, prenatal needs, or limited studio space. Inflate fully using the fast pump, then let the ball sit for 48–72 hours to allow the material to stretch; re-inflate as needed to reach the correct firmness for stability and comfort.
Who is this for? The STOROMO 45cm exercise ball is aimed at expecting parents seeking a supportive birthing and comfort tool, shorter users who want a compact stability ball, people doing Pilates or light rehabilitation, and anyone looking for an anti-burst, non-slip seat alternative for home or office. If you want a highly portable, easy-to-inflate ball with an exercise guide and a textured grip for safer movement, this model is well suited to those needs.
Q: Is the STOROMO exercise ball safe for pregnancy?
A: Yes. It’s extra-thick, non-slip, and supplied with setup guidance, making it suitable for pregnancy support and gentle movement.
Q: How do I inflate the ball correctly?
A: Use the included fast pump, inflate, let the ball rest 48–72 hours, then top up to reach final firmness.
