Office Chair Locking Casters

Office chair locking casters can be implemented in the following ways, and the specific choice should be based on the usage scenario and requirements:

1. Use casters with locking functions
These casters typically have a diameter of 60 millimeters and are covered with a soft PU layer and equipped with a noise-reducing sleeve. They can protect the floor from scratches and reduce noise during movement. The core design features a locking mechanism on the side or bottom of the caster. When the user needs to fix the chair, they simply pull down the locking mechanism to stop the caster from rotating; when movement is required, they lift the mechanism to unlock it. This design is easy to operate and suitable for scenarios where temporary chair fixation is needed, such as preventing chair sliding during office work.

2. Use fixed foot pads
Fixed foot pads replace the original casters through a snap-in design, creating a rigid connection between the chair and the floor, making the chair completely immobile. Their advantage lies in extremely high stability, especially suitable for scenarios involving the elderly, children, or where absolute chair fixation is required (such as medical or laboratory environments). However, the drawback is that each foot pad must be removed individually for movement, which is relatively cumbersome, and frequent insertion and removal may affect the lifespan of the foot pads.

3. Choose gravity self-locking casters
Gravity self-locking casters utilize the user's body weight to trigger the locking mechanism: when the user sits down, the spring or hydraulic device inside the caster is compressed, automatically locking the caster; when the user stands up and the pressure disappears, the caster unlocks and resumes movement. This design requires no manual operation and is suitable for scenarios requiring frequent switching between fixed and mobile states (such as meetings or training sessions). However, it is important to note the sensitivity of the casters to body weight, as being too light or too heavy may affect the locking effect.

4. Replace with casters with brake functions
Some casters support individual locking or unlocking, but usually require simultaneous operation of all five casters (such as through foot pedals or hand-operated devices), making the operation slightly complex. Their advantage lies in the ability to flexibly control the state of each caster, suitable for scenarios requiring partial fixation (such as locking only the front casters). However, they come with higher costs and greater maintenance difficulty.

Supplementary solution: Lay down rough carpets
If the requirement for fixation is not high, a rough carpet can be laid under the chair to increase friction and restrict chair movement through physical resistance. However, this method cannot completely fix the chair, and the carpet may affect the smoothness of chair movement, serving only as a temporary or low-cost solution.
