No specific product information about the 'Hongye 1105 Office Chair' has been found. Here are some general suggestions for selecting an office chair:

When choosing an office chair, if detailed specifications for a specific model (such as the Hongye 1105) are unavailable, you can evaluate the product from four dimensions: core functionality, materials, ergonomic design, and brand and after-sales support to ensure it meets your usage needs.

1. Core Functionality Adaptability
The core functions of an office chair include posture support, height adjustment, and rotational and mobility flexibility. Choose a combination of functions based on your usage scenario:

• Basic Functions: Pneumatic height adjustment rods (for adjusting seat height) and five-star casters (for 360° rotation and mobility) are standard features. Ensure the pneumatic rod has passed safety certifications such as SGS to avoid explosion risks.
• Advanced Functions: If you need to work for long hours, prioritize models with adjustable lumbar support and headrests to distribute spinal pressure. If space is limited, choose models with locking wheels to prevent accidental movement.

2. Material Durability and Comfort
Materials directly affect the lifespan and sitting comfort of the chair:

• Seat and Backrest: Opt for high-density foam (good resilience) or mesh (breathable) materials. Avoid recycled cotton (prone to sagging) or low-density foam (insufficient support) commonly used in cheap office chairs.
• Frame and Five-Star Base: Metal frames (such as steel) are more stable and have stronger load-bearing capacity than plastic. For the five-star base, choose nylon reinforced with glass fibers for a balance of lightweight and durability.
• Armrests: Adjustable armrests (up/down, forward/backward, left/right adjustment) can accommodate users of different heights, while fixed armrests are suitable for compact spaces.

3. Ergonomic Design Rationality
Ergonomic design is key to reducing fatigue from prolonged sitting:

• Lumbar Support: The chair back should conform to the lumbar curve, with adjustable lumbar support height being ideal to avoid lumbar suspension.
• Seat Depth Adjustment: The seat depth should support at least two-thirds of the thigh length to prevent impaired blood circulation in the legs.
• Recline Angle: The recommended chair back recline angle is between 100° and 120°, with a locking function to facilitate switching between work and rest modes.

4. Brand and After-Sales Support
Prioritize brands with clear warranty policies:

• Warranty Period: Reputable brands typically offer a 3-5 year warranty covering core components such as the pneumatic rod and frame.
• After-Sales Service: Confirm whether on-site repairs or part replacements are supported to avoid disputes during subsequent use.
