Fixed Backrest Office Chair

The installation, safety hazards, and purchasing suggestions for fixed backrest office chairs are as follows:

I. Installation Method

The installation of fixed backrest office chairs is usually relatively simple. Taking the Jinyexing 198 computer chair as an example, the steps for installing its backrest are as follows: Align the backrest cover with the holes on the backrest and simply snap it on to complete the fixation. This type of design enables quick assembly through a snap-fit structure without the need for complex tools, making it suitable for self-installation in home or office settings. However, it should be noted that before installation, check whether all accessories are complete, ensure that the holes are aligned before applying force to snap them together, and avoid breaking the snaps or misaligning the holes due to improper force application.

II. Safety Hazards and Supervision

Some fixed backrest office chairs have safety hazards due to design or material issues, which require special attention:

1. Backrest Breakage Risk: In March 2023, the United States and Canada recalled office chairs made in China because the connection points of the backrests might break due to insufficient material strength or long-term use fatigue, causing users to fall when leaning back.
2. Failure of Fixed Components: In January 2025, the United States recalled WorkPro Momentum office chairs because the bolts fixing the backrests might fail due to design defects or improper installation, causing the backrests to separate from the chair bodies. Users might be injured by sudden falls while sitting.
   Suggestions: When purchasing, give priority to products that have passed international safety certifications (such as the BIFMA standard). Regularly check the connection points of the backrests for cracks, looseness, or abnormal noises, and avoid long-term overloading.

III. Purchasing Suggestions

The prices of fixed backrest office chairs on the market vary greatly, and choices should be made according to needs:

1. Limited Budget: Simple plastic backrest chairs cost about ¥28.0 and are suitable for temporary or low-frequency use. However, it should be noted that their load-bearing capacity and durability may be relatively low.
2. Long-term Use: Ergonomic design chairs cost about ¥623.75. They usually feature high-density foam or breathable mesh backrests and support multi-position adjustments for the waist and neck, making them suitable for people who sit for long periods in an office setting.
3. Service Guarantee: Give priority to merchants that offer services such as "7-day replacement" and "48-hour delivery" to reduce after-sales risks.

Summary: The installation of fixed backrest office chairs should be carried out in accordance with the instructions. During use, regularly check the safety performance. When purchasing, comprehensively consider the budget, usage scenarios, and safety certifications to avoid safety hazards caused by low prices or design defects.
