Castors are an essential addition to commercial and domestic furniture where ease of movement is required. The improved manoeuvrability they provide reduces strain for the user and helps protect the furniture item and the floor surface on which they’re moving. When choosing furniture castors, it’s vital to select the correct size and weight for the purpose. See our tips below and ensure you make the right choice.

When the correct castors are applied to furniture, they can be a productive and attractive addition.

Risks of Using the Wrong Castor

Choosing the incorrect castor for your furniture carries the following risks:

  • It could make it impossible to move the furniture or drastically reduce its manoeuvrability.
  • It could potentially harm the user.
  • It could damage the furniture.
  • It could damage the floor surface.

How to Select the Correct Castors for Furniture

By considering these three key factors, you can ensure you choose the correct castor for the job:

  • floor type
  • furniture weight
  • user environment

Floor Type

Consider the floor surface on which the furniture will move. If the floor is concrete, wood or tile, soft rubber castors can be a great choice because they won’t mark the floor and are quieter. If the floor is soft or uneven, polyurethane or nylon castors may be a better choice, as they’re harder and offer better traction. Generally, the larger the wheel, the easier it is to push over most surfaces.

Furniture Weight

The weight of the furniture also plays a major role in determining the right castor. Castors are available in light, medium and heavy weights. Light castors can only support about 65 kilograms each, while heavy duty castors can support considerably more weight.
Working out the load-bearing capacity of castors is essential for safety and productivity. The castors on a piece of furniture share the weight so, to determine load-bearing capacity, do the following:

  • Divide the weight of the furniture item by the number of castors required.
  • For chairs, make sure you add the user’s weight to your calculation.
  • Factor in a safety margin of about 20–30 per cent.

Double-wheel castors may be a useful option for some furniture items because they can bear considerably more weight but are smaller in size.

User Environment

Finally, the unique environment for your application may require particular features in your castors to ensure they perform optimally. Are there extremes in temperature, chemicals in use, or health and hygiene considerations? Would a rigid fixed castor be better than a swivel? Before choosing a castor, check the features of each castor to make sure they are the ideal choice for the environment.
