Sizing is based on height, same as our general guide: under 5'4" suits our 55cm ball, 5'4"–6'0" suits our 65cm ball. This applies whether you're using it at your desk, or just for general sitting and movement around the home.

Yes. Sizing is based on height, not stage of pregnancy, so there's no need to size up or down as things progress. What can change is how it's used: for desk work, the usual comfortable position is hips and knees roughly level, while later on, many people prefer sitting with hips slightly higher than knees, which comes down to inflation rather than a different ball. As always, your healthcare provider is the best person to guide what feels comfortable for your body.

We'd always encourage it. Everyone's pregnancy is different, and your healthcare provider is best placed to advise on what's right for you. What we can tell you is that the ball is designed for gentle, low-impact movement, which many people find comfortable during pregnancy.

There's no set amount of time. This will be different for everyone and it will depend on how your body feels. Most people start with short intervals and go from there. For anything specific to you, your healthcare practitioner is the right person to speak to.

A mat is not critical but if your floor is slippery, we would highly encourage you to ensure the ball is placed on a mat.

The ball comes in a box with the cover, a hand pump, plugs and instructions. You can also purchase a cover individually when you want to upgrade your colour or fabric.

Yes. The cover is machine washable on a warm gentle machine wash at approx 40 degrees.

We have a less than 1% return rate so most of our customers love the ball. For extra peace of mind, we offer a 60 day returns policy so you can try the ball and if it's not working for you, you are welcome to email us and we'll happily arrange an exchange or refund.
