Frequently Asked Questions

What size ball is right for me?
TheraBand uses a color-coded sizing system based on user height. The 18-inch (45cm) yellow ball is generally recommended for users approximately 4 feet 8 inches (142cm) and under. When seated on the ball, your hips and knees should be at approximately 90-degree angles.

Does a pump come included?
A pump is not included. The ball 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?
