Fixation of Computer Chairs and Office Chairs

There are multiple methods to fix computer chairs and office chairs, as detailed below:

1. Fixing Swivel Office Chairs with Professional Accessories

   • Chair Fixed Feet: Replace the original casters directly. After installation, the chair cannot move at all, providing a thorough fixing effect, but sacrificing mobility. Suitable for scenarios requiring long-term fixation without the need for movement.
   • Wheels with Brakes or Gravity Self-Locking: Wheels with brakes require manual locking and unlocking one by one; gravity self-locking wheels are smarter, unlocking for rolling when someone sits on them and automatically locking when they leave, balancing convenience and stability.
   • Swivel Chair Wheel Covers/Fixers: Accessories that directly clamp onto existing rollers, easy to install without tools, effectively locking the wheels to prevent sliding and noise, while protecting the floor (such as wooden floors, tiles) from scratches.

2. Low-Cost Techniques to Increase Friction

   • Paper-Stuffing Method: Fold A4 paper and stuff it into the wheels to significantly increase rolling resistance, making the chair difficult to slide but not completely fixed, suitable for temporary or low-cost needs.
   • Carpet-Laying Method: Lay rough carpets in the chair's activity area to restrict sliding by increasing floor friction, an environmental modification solution suitable for large-area fixation needs.

3. Installing Anti-Slip Foot Pads for Fixed-Leg Chairs

   • Material Selection: Silicone material is soft, offering excellent anti-slip and cushioning effects; EVA pads have good elasticity; felt pads are lightweight and quiet. Self-adhesive designs are easy to install, but some products may have an initial odor.
   • Adaptation and Installation: Choose foot pads with an appropriate inner diameter based on the shape of the chair legs (round or square). Ensure that all four foot pads completely wrap around the bottom of the chair legs and are at the same height during installation to avoid instability caused by a shifted center of gravity.

4. Using Seat Anti-Slip Pads with Straps
   Suitable for chairs with hard seats, these pads have silicone anti-slip particles on the back to grip both the seat and the floor; the straps on both sides firmly fix them to the chair, solving issues of seat sliding and discomfort from prolonged sitting.

5. Structural Reinforcement for Wobbly Wooden Chairs

   • Filling Gaps: Insert wooden wedges into loose mortise-and-tenon joints to fill gaps and restore tightness.
   • Enhancing Connections: Use metal L-shaped corner brackets to fix the right-angle connections between chair legs and crossbars.
   • Adding Supports: Add diagonal braces between chair legs to form a stable triangular support structure, fundamentally enhancing stability.
