Office Chair Core

The core of an office chair involves core parameters, core types, and core brand-related elements.

Core Parameters:

• Lumbar Support: It is the soul of the entire chair, with the core function of supporting the 2nd to 3rd lumbar vertebrae and maintaining the natural physiological curvature of the spine. A qualified lumbar support should be height-adjustable, with an adjustment range of no less than 5 cm, and provide moderate support. Self-adaptive elastic lumbar supports perform well.
• Headrest: The correct height should be level with the line connecting the ears and shoulders, and the angle should be adjustable. When leaning back, it should firmly support the cervical spine and provide comfortable support for the neck.
• Armrests: Their function is to relax the shoulders. Choose at least 2D armrests that can be adjusted up and down and forward and backward. If the budget allows, 4D armrests are recommended, which can also rotate left and right and flip inward to meet the needs of different usage scenarios.
• Seat Cushion: Mesh seat cushions have good air permeability but are prone to collapse. For those weighing over 80 kg, it is recommended to choose a combination seat cushion of high-density memory foam and latex layers to provide better support and comfort.
• Gas Lift: It is related to personal safety and needs to pass SGS or BIFMA certification, with a grade of 3 or 4, to ensure stability during use.

Core Types:

• Ergonomic Chair: Through adjustable headrests, lumbar supports, and armrests, it supports the spine like a living skeleton, effectively relieving fatigue from prolonged sitting and is suitable for people who work at a desk for long periods.
• Mesh Chair: Its advantage lies in air permeability. Sitting for long periods in summer will not be unbearably hot, providing users with a relatively refreshing sitting experience.
• Leather or Solid Wood Chair: It focuses more on durability and appearance and is commonly seen in meeting scenarios. However, its air permeability is relatively weak, and it has certain advantages in terms of aesthetics and durability.

Core Brand-Related Aspects:

• Qualification Certifications: Regular office chair brands must have a series of authoritative certifications, such as National High-Tech Enterprise Certification, ISO9001 Quality Management System Certification, and China Green Product Certification. For overseas exports or procurement scenarios of multinational enterprises, international GREENGUARD GOLD Certification and EU EN 1335 Standard Certification are even more essential qualifications.
• Technical Strength: It is reflected in ergonomic research and development and a full-industry chain layout. Leading brands have their own research and development centers, focusing on the combination of ergonomics and office chairs to solve core pain points such as fatigue from prolonged sitting and posture correction. A full-industry chain layout can control every link from raw material production to finished product assembly, ensuring stable product quality and controllable delivery cycles.
