How do Braking Casters work?

Braking casters are designed to brake while the chair is not in use. When seated, the mechanism releases to allow movement. They are not designed to brake while the chair is in use. 

What type of carpet do Carpet Casters work best with?

Carpet casters are hard plastic casters that will work best on commercial-style carpets, but they can be used on any carpet. The deep carpet casters are recommended for shag or plush rugs. 

It's not recommended to use carpet casters on hard floors. They won't mark up your floors, but they won't provide an optimal level of traction. Long-term use of carpet casters on hard floors can cause damage to the casters as well.
