Stop Office Chair Wheels

There are several main methods to stop office chair wheels:

I. Replace with Special-Function Wheels

1. Lockable Wheels: These wheels typically have a diameter of 60 millimeters and are wrapped in soft PU material, which reduces metal friction noise and protects solid wood floors. The locking mechanism can be switched by manually掰动 (掰动 can be translated as 'flipping' or 'turning' in this context, but for clarity, we'll use 'flipping') the locking device on the wheel: flip it down to lock the wheel and up to unlock it for movement. A set includes 5 wheels, providing strong stability suitable for scenarios requiring frequent switching between fixed and mobile states.
2. Gravity Self-Locking Wheels: These wheels use gravity-sensing design. When a person sits on the chair, the internal mechanism of the wheel automatically locks due to gravity, and unlocks when the person stands up. This design requires no manual operation and is suitable for office or study scenarios where 'sitting still means being fixed'. However, note that individuals with very light body weight may not trigger the locking mechanism.
3. Light-Duty Caster Dual-Brake Structure: A dual-locking mechanism designed specifically for office chairs, it can simultaneously restrict the rolling and rotational degrees of freedom of the wheels. Precise positioning is achieved through foot or manual operation, suitable for environments requiring high stability, such as hardwood floors or standing desks. However, the operational complexity is slightly higher than that of single-function wheels.

II. Physical Fixing Devices

1. Fixed Foot Pads: Insert the foot pads into the wheel interface of the chair to prevent sliding by increasing the contact area and friction. These devices are easy to install and suitable for use by the elderly or children. However, the chair must be completely disassembled to move after fixing, offering low flexibility.
2. Chair Fixed Feet: Directly replace the original wheels with flat-contact designed fixed feet, providing strong fixing effects but completely losing mobility. Suitable for scenarios requiring long-term chair fixation, such as laboratories or operating rooms with extremely high stability requirements.

III. Environmental Adjustment Method Laying Carpets: Lay a rough-textured carpet under the chair to slow down sliding speed by increasing friction. This method is low-cost and easy to implement but cannot completely fix the chair, and carpet cleaning and maintenance are cumbersome. It is suitable for temporary scenarios with low fixation requirements.

IV. Brake Wheels These wheels require simultaneous operation of the brake devices on all five wheels to achieve locking, and the same for unlocking. Although the fixing effect is reliable, the operational convenience is low, suitable for users with high safety requirements who do not mind operational complexity.

Selection Suggestions:

• If frequent switching between fixed and mobile states is required, prioritize lockable wheels or gravity self-locking wheels;
• If long-term fixation is needed without sacrificing mobility being a concern, choose chair fixed feet;
• For families with elderly/children or requiring temporary fixation, fixed foot pads or carpets are low-cost solutions;
• For office environments requiring precise positioning, recommend the light-duty caster dual-brake structure.
