The Posture People guide to Castors and Glides

When you are ordering a chair with us, the more information you can give us about your working environment, the easier it is for us to find you your perfect chair.

One thing to consider is the type of flooring that you have in your workspace. Our chairs can be specified with a range of ‘feet’ to make sure that you stay safe and comfortable whilst you work. These vary from castors (wheels), glides (a flat foot) dependent on the high of the chair and the environment that you are working in i.e on a hard floor, or a soft floor such as carpet.

We’ve made this guide to castors & glides to help you make an informed decision when choosing what ‘feet’ your chair will need.


Brake-loaded castors can be wheeled freely until weight is applied. This locks the wheel until the weight is lifted.

Interval break-loaded castors are partially braked consistently to make mounting the chair safer on hard floor surfaces. The wheel will lock completely when weight is applied.

Free-wheeling castors are break-free for ease of movement suiting most office environments where people are working at a normal height.

If you have carpet, choose castors for soft floor which means the castor won’t have a rubber overlay that will ‘drag’ on the carpet.

If you have a hard floor such as wood, choose hard floor castors so that the rubber overlay will protect the floor from scratches and wear.


Glides are flat disks that are usually fitted on higher chairs and stools to ensure that the chair does not slip away when you mount the chair. You might find that glides are also a better choice for chairs that don’t require much movement such as meeting room chairs.


Both castors and glides can be made in specialist materials to make them suitable for the requirements for your environment such as a cleanroom or static dissipative floor.
