How do you choose a Swiss Ball during pregnancy?

You're expecting a little bundle of joy, but which Swiss ball should you choose?
You will need different ball sizes as your pregnancy progresses and you gain weight
As a safety precaution, and so that you don't have to buy multiple balls, we recommend choosing a ball that is one size bigger than you would normally need
It is essential that you follow the safety instructions to the letter so that you stay safe.

How to safely inflate your Swiss ball

We recommend using a pump, which is sold separately
Before inflating your ball, leave it at room temperature (20°C) for 24 hours
Inflate the ball slowly so it does not get damaged
Inflate the ball to 2/3 of its max size, at a temperature of between 20°C and 25°C max, then wait 2-3 hours
Finish inflating it to the desired size but do not go over the maximum size
Leave the ball for 24 hours before using it and check the size and adjust it if necessary

Why choose a Stable Swiss Ball?

Inflate your ball
Remove the pump's nozzle from the hole
Plug the hole with your finger, with the stopper in your other hand
Sit on the ball and adjust the size, then put the stopper in the hole
Intended for:
Pilates - when sitting on the ball your knees should be bent to 90° and at the same height as your hips, or slightly higher
Office - adjust the ball's height so that your elbows are at the same height as the top of your desk

The story behind this ball

2 years ago, Bruno, our Pilates accessories product manager, took physical therapy sessions for a herniated disc. His physical therapy included exercises with a Swiss Ball. The ball often rolled to the other end of the room between exercises, which gave him an idea. With advice from Dorian, his physical therapist, he developed this weighted Swiss Ball.

Our balls are puncture resistant so that they won't suddenly burst as you use them
If it does get punctured, your ball will deflate slowly
To work:
The ball's surface should not have any scratches or rub marks
The floor should be clean and void of any sharp/pointy objects
You must follow the use restrictions, inflation instructions, storage instructions and maintenance advice, and not exceed the size
