Selection of Environmentally Friendly Office Chairs

When selecting environmentally friendly office chairs, you can focus on brands such as JD.COM Manufacturing and NetEase Yanxuan, and consider them comprehensively from three aspects: support system, adjustment function, and safety and durability.

Brand Recommendations

• JD.COM Manufacturing: It focuses on the environmental friendliness of materials and emphasizes reducing the release of harmful substances from the source. For example, it uses environmentally friendly fabrics with low volatile organic compounds (VOCs) to ensure that the chair does not release harmful gases such as formaldehyde during long-term use, providing users with a healthy and safe sitting environment.
• NetEase Yanxuan: It emphasizes the recyclability of materials. Some of its products use recycled plastics or biodegradable materials to reduce resource consumption. At the same time, it has passed international environmental certifications (such as OEKO-TEX Standard 100) to ensure that the materials have no negative impact on user health and the ecological environment.

Key Points for Selection

1. Support System

   • Dynamic Lumbar Support: Prioritize the selection of split-type dynamic lumbar support designs, which can automatically adjust the support points and intensity according to changes in sitting posture. For example, they cover the L1-L5 lumbar spine regions to relieve fatigue from prolonged sitting. The adjustment range of the lumbar support should cover the height requirements of different users. Some products can achieve a lifting range of more than 70 millimeters, suitable for people with heights ranging from 150 to 190 centimeters.
   • Cervical Spine Support: It is recommended that the depth of the headrest be at least 128 millimeters to ensure that the cervical spine fits naturally and avoids hanging in the air. Some products support angle adjustment of the headrest to further match different sitting postures.

2. Adjustment Function

   • Seat Depth Adjustment: Adjust the depth of the seat cushion through slide rails or telescopic structures to ensure that the thighs are evenly stressed and the back of the knees is not compressed, especially suitable for users with significant height differences.
   • Armrest Design: The armrests should support multi-dimensional adjustment (such as up and down, front and back, left and right rotation) to keep the elbows in a natural and relaxed state when typing, reading, or leaning back, reducing shoulder and neck pressure.

3. Safety and Durability

   • Gas Lift Certification: It is essential to choose gas lifts that have passed SGS or TUV Level 4 certification. These products have undergone strict pressure tests and can withstand more than 200,000 lifting operations, avoiding the risk of explosion.
   • Frame Material: Priority should be given to one-piece steel frames or high-strength engineering plastics to ensure a load-bearing capacity of more than 150 kilograms and no deformation during long-term use.
   • Seat Surface Material: Highly elastic and breathable mesh fabric can quickly dissipate heat and moisture, suitable for summer or prolonged use. High-density foam seat cushions should recover within 3 seconds after being pressed to avoid sagging.
