Fixed-Wheel Office Chair

Fixed-wheel office chairs can be achieved through various accessories and methods, as detailed below:

1. Fixed Foot Pads
   Fixed foot pads are non-wheeled accessories that are inserted directly into the chair legs by replacing the original wheels, rendering the chair completely immobile. Their design is simple and installation is easy, making them suitable for scenarios where chairs need to be fixed for long periods, such as in laboratories or at drafting tables that require stable support. Some products are equipped with anti-slip rubber or felt pads at the bottom to further enhance friction with the ground and prevent sliding.

2. Wheels with Brake Pads
   These wheels incorporate a braking mechanism on traditional caster wheels, allowing the wheels to be locked by stepping on or pressing the brake pads. The brake pads are typically located on the side or top of the wheels and require foot or hand activation for operation. Once fixed, the wheels cannot rotate or slide. They are suitable for scenarios that require frequent switching between mobile and fixed states, such as in conference rooms or classrooms.

3. Seat-Activated Brake Wheels
   Seat-activated brake wheels utilize gravity-sensing design. When a person sits on the chair, the internal mechanical structure of the wheels automatically locks, preventing movement; when the person stands up, the lock is released, restoring the sliding function. These wheels require no manual operation and are suitable for scenarios that require temporary fixation, such as when making phone calls or focusing on work while seated at a desk. However, it should be noted that a light body weight may affect the locking effect.

4. Wheels with Locking Function
   These wheels, typically with a diameter of 60 millimeters, are equipped with locking buttons or levers. To fix the chair, press the button or flip the lever to lock the wheels; to move the chair, unlock it to restore sliding. Their advantage lies in intuitive operation, making them suitable for scenarios that require precise control over chair movement, such as in medical care or precision operations.

5. Gravity Wheels
   Gravity wheels sense changes in gravity through their internal mechanical structure. When the chair bears weight, the internal resistance of the wheels increases, making movement more difficult and thus indirectly achieving a fixed effect. These wheels require no additional operation, but the fixing effect is influenced by body weight, making them suitable for scenarios that require slight restriction of movement, such as in home offices or leisure areas.

6. Spring-Loaded Insert Foot Pads
   Spring-loaded insert foot pads are secured to the chair legs using spring clips, with some products including felt pads to enhance anti-slip properties. During installation, align the foot pads with the holes in the chair legs and insert them; the spring clips will automatically lock. Their structure is sturdy, making them suitable for scenarios that require long-term fixation and a flat ground surface, such as in industrial offices or warehousing environments.

In addition, the market offers fixed casters and swivel casters in various sizes, such as 1.5-inch and 2-inch options, which can be selected based on the chair model and floor material. Braked models are suitable for scenarios that require temporary fixation, while non-braked models are suitable for fixed scenarios where no movement is needed.
