Office Chair Shock Absorption

The core of office chair shock absorption lies in selecting the appropriate type of shock absorber and paying attention to key parameters such as damping adjustment, load-bearing capacity, material, and compatibility. Here is a detailed analysis:

1. Selection of Shock Absorber Types

• Spring-type: For example, the Sihoo C500 office chair is equipped with four shock-absorbing springs. These springs disperse sitting pressure through deformation, providing a soft and elastic sitting experience, suitable for users seeking comfort. Its net pressure load-bearing capacity reaches 2200 jin (1100 kg). The bottom four-stage gas lift, combined with a jack pressure test, ensures stability.
• Pneumatic-type: Mainly using gas cushioning, it offers a stable and quiet sitting experience, suitable for office scenarios with a load-bearing capacity of less than 100 kg (such as the recommended type in Anqing). It is important to pay attention to the certification level of the gas lift to avoid safety hazards caused by inferior products.
• Adjustable-seat type: It adapts to people of different weights through damping adjustment (1-5 levels), with a recommended stroke length of 15-25 mm. For example, products from Enshi factories use high-strength carbon steel materials, undergo 12 precise processing steps and 24-hour pressure tests, offering excellent cost-effectiveness. When purchasing in Changsha, it is necessary to look for SGS-certified silicone seals and 304 stainless steel metal parts.

2. Core Parameters and Functions

• Damping adjustment: High-quality shock absorbers support multi-level adjustment (such as 1-5 levels). Office workers who sit for long periods can give priority to the "dual-axis adjustable" type, which can simultaneously adjust the upper and lower damping and the front and rear rebound force, adapting to multiple scenarios such as desk work and typing.
• Rebound mode: Some products support "gentle rebound" or "fast rebound", and users can choose according to their usage habits (such as the recommended type in Anqing).
• Sealing and material: Silicone seals need to be SGS-certified, and metal parts should preferably be made of 304 stainless steel to prevent air leakage or corrosion.

3. Compatibility and Pitfalls to Avoid

• Load-bearing limit: Before purchasing, it is necessary to confirm the load-bearing range indicated on the product. Exceeding the weight limit may cause damage to the shock absorber (for example, the load-bearing capacity of pneumatic-type shock absorbers is generally ≤100 kg).
• Installation compatibility: Measure the aperture size and installation hole spacing of the seat base, and give priority to products that support "M6/M8 universal interfaces" to avoid installation failures due to size mismatches.
• Quality control: Be cautious when choosing low-priced off-brand products. Give priority to products produced by large manufacturers with warranties. Be wary of excessive publicity such as "adjustable = universal", and the actual effect needs to be verified in combination with parameters.

4. Scenario-based Recommendations

• When paired with a computer desk, choose a "vertical compression-type" shock absorber to reduce the transmission of vibrations during keyboard and mouse operations.
• If long-term desk work is required, it is recommended to choose products with a wide range of damping adjustment and adjustable rebound force to relieve lower back pressure.
