Office Chair Caster Fixing

There are several main methods for fixing the casters of office chairs:

I. Using Fixed Feet Fixed feet are accessories that directly replace the original casters. They fix the chair to the ground through a physical structure. Their advantage lies in stable fixing effects, especially suitable for scenarios that require long-term stillness, such as laboratory workbenches and drawing tables. However, the drawback is that the chair cannot be moved after installation, significantly reducing flexibility. It is necessary to weigh the use based on actual needs.

II. Using Casters with Brakes These casters fall into two categories:

1. Manual Brake Casters: Each caster's brake device needs to be operated individually. Once locked, the casters are completely stationary. They are suitable for scenarios that require frequent switching between moving and fixed states, but the operation is cumbersome, especially when the chair is equipped with five casters, as all of them need to be locked simultaneously.
2. Seat-Activated Brake Casters: The brake mechanism is triggered by the user's body weight. When sitting down, the casters are automatically locked, and they can slide when getting up. This design takes into account both safety and convenience, suitable for the need for short-term fixing in office scenarios, such as preventing the chair from sliding when making phone calls or writing.

III. Installing Gravity Self-Locking Casters Gravity self-locking casters combine the automatic locking principle of seat-activated brake casters with the flexibility of universal casters. Their core design is to trigger the internal brake structure through a spring or gravity sensing device when the user sits down, making the casters unable to rotate; when getting up, the brake is automatically released, restoring the sliding function. These casters do not require additional operations and are suitable for scenarios that require efficient switching between states, such as conference rooms and training rooms.

IV. Using Fixed Accessories Some accessories achieve fixing through physical blocking, such as insertable corner brackets or dedicated clips. After installation, these accessories restrict the rotation or sliding range of the casters, making the chair immobile. This method has a relatively low cost, but it is necessary to ensure that the accessories match the chair model and may affect the original aesthetic design of the chair.

V. Laying Anti-Slip Fixing Pads Anti-slip pads prevent the chair from sliding by increasing friction. Common types include:

• Rubber Slot-Type Fixers: They are inserted between the casters and the ground, using the high friction coefficient of rubber to achieve fixing.
• Felt-Based Fixers: They generate static friction with the ground through the softness of the felt material, suitable for wooden floors or tiled floors. These methods do not require modifying the chair structure, but it is necessary to regularly clean the pad surface to maintain the anti-slip effect, and they have relatively high requirements for ground flatness.

Additional Information: There are also composite products on the market, such as spring-inserted foot pads and brake-equipped universal casters. Users can make a comprehensive choice based on the chair model, usage scenario, and budget. For example, for home office scenarios, seat-activated brake casters or anti-slip pads can be given priority, while for industrial environments, fixed feet or gravity self-locking casters are more suitable.
