This small Swiss ball is 45cm across and purple. It’s sized for children, who use it as a wobbly seat at a desk or for play, and it also works for core stability and rehab exercises. The ball is anti-burst and comes with a foot pump and a spare plug, so you can blow it up as soon as it arrives.
Who a 45cm ball suits
Swiss balls are sized by the user’s height. Sitting on the right ball with your feet flat, your hips should be level with or a little above your knees. A 45cm ball is the child size, so most adults will need a larger one. Our exercise ball size guide matches each ball size to a height range if you’re not sure which to buy.
Ways to use it
- As a seat for kids at a desk or table, where the small movements help them get the wiggles out
- Play and balance games
- Core stability work such as seated balance and bridges
- Gentle rehab exercises set by a physio

Setting it up
Inflate it gradually rather than all at once, and top it up if it softens over time. Keep it away from sharp edges and heaters. When your child sits on it, check their feet reach the floor flat, which is the easiest way to tell the size is right.
Other sizes and colours are in the Swiss Balls range.
