Why is our gym ball not suitable for office use?

Our ball is designed for fitness activities, so it's not suitable for office use. Restrictions associated with office appropriate products prevent us from recommending it for this purpose. However, we know what you want and we have a special surprise in the works just for you!

What should you do if you lose both your gym ball plugs

Don't worry! This year, we're offering the option to buy plugs as spare parts in the store's workshop. So wait no longer, visit your nearest Decathlon store.



Product testing

To guarantee quality and safety, we perform numerous tests before our balls hit the shelves. There are 2 main tests: - A repeat compression test: We compress the ball more than 100,000 times with a weight of 430 lbs. - A static compression test: We compress the ball with a weight of 715 lbs.

Storage instructions
