Frequently Asked Questions

What size ball is right for me?

TheraBand uses a color-coded sizing system based on user height. The 18" (45cm) yellow ball is generally recommended for users approximately 4’8” (142cm) and under, or for specific therapy exercises where a smaller ball is prescribed. When seated on the ball, your hips and knees should be at approximately 90-degree angles. Always follow your physical therapist’s recommendation for your specific program.

Does a pump come included?

A pump is not included with this ball. It can be inflated with any standard hand pump or foot pump. Most users find a foot pump with a needle adapter to be the fastest and easiest option.

Can this ball be used as a desk chair?

Yes — many users use exercise balls as an active sitting alternative to promote core engagement and improve posture during desk work. The 18" size is best suited for lower desk heights or shorter users. Ensure the ball is fully inflated and placed on a non-slip surface.

Is this ball latex-free?

TheraBand exercise balls are made from PVC and are latex-free, making them suitable for users with latex sensitivities. If you have a known latex allergy, confirm with your healthcare provider before use.
