Office Chair Shock Absorption Accessories

Office chair shock absorption accessories mainly include three categories: shock-absorbing casters, shock-absorbing brackets (specific models), and table leg shock-absorbing protective sleeves. Their functions and design principles are as follows:

1. Shock-Absorbing Casters: Directly Buffering Movement Impact

Shock-absorbing casters are the core accessories for shock absorption in office chairs, achieving buffering effects through material or structural design. Common types include:

1. Polyurethane/PU-edged Universal Casters: Such as the "Cross-border Amazon 2-inch Universal Caster" and the "Polyurethane Snap-in Flat Silent Caster with Card Spring", these casters use polyurethane or PU-edged materials, which are wear-resistant and have good elasticity. They can effectively absorb vibrations caused by uneven ground surfaces, with prices around ¥1.19.
2. Hollow Threaded Rod Insert Casters: Such as the "2.5-inch Hollow Universal Caster", these casters reduce weight through a hollow structural design while utilizing the elasticity of the threaded rod insert to buffer movement impact. They are suitable for quiet office environments, with prices around ¥13.5.
   Purchase Recommendations: Prioritize casters made of polyurethane or PU materials, as their shock-absorbing performance is superior to that of ordinary rubber casters. If a silent effect is required, pay attention to models with card springs or hollow designs.

2. Shock-Absorbing Brackets: Upgrading Chassis Buffering Capacity

Although not specifically designed for office chairs, the principles of some shock-absorbing brackets can be borrowed for high-end office chair designs. For example, the "Bigod Master T4 EX30 Shock-Absorbing Bracket" achieves shock absorption through the following methods:

1. Spring Pressure Release: Utilizes the elastic deformation of springs to absorb vertical vibrations, reducing the bumpiness of the chair surface.
2. Metal/Nylon Isolation Columns: Disperses impact forces through the damping characteristics of the materials, reducing structural resonance.
   Application Scenarios: If the office chair itself vibrates significantly (such as due to aging of the gas lift or insufficient rigidity of the chassis), check whether it supports upgrading to a shock-absorbing bracket, but ensure compatibility with the specific model.

3. Table Leg Shock-Absorbing Protective Sleeves: Assisting in Reducing Indirect Vibrations

The "Bobo Department Store Table Leg Protective Sleeve" uses a thickened rubber + felt design. Although primarily used for table legs, it can indirectly reduce noise and vibrations when moving office chairs:

1. Rubber Buffering: The thickened rubber layer absorbs part of the impact force, reducing the intensity of collisions between the chair casters and the ground.
2. Felt Silencing: The felt layer reduces friction noise, suitable for hard floor environments.
   Limitations: Its shock-absorbing effect is limited and is more suitable as an auxiliary accessory, unable to replace dedicated shock-absorbing casters or brackets.

Summary: Choosing accessories for office chair shock absorption should be based on needs—prioritize shock-absorbing casters for movement buffering, consider shock-absorbing brackets for structural upgrades, and use table leg protective sleeves for auxiliary noise reduction. When purchasing, pay attention to material, design, and model compatibility to ensure shock-absorbing effectiveness and usage safety.
