Ordinary Office Chair Purchase Guide

When purchasing an ordinary office chair, it is necessary to comprehensively consider the budget and needs. Here are the specific key points:

When the budget is limited, focus on basic performance

1. Weight and metal tube thickness: Prioritize chairs with greater weight. If a chair is too light, its metal tubes may be thin (e.g., 0.8 mm), resulting in insufficient load-bearing capacity. Usually, metal tubes over 1.2 mm can meet daily load-bearing requirements, but people with a large body weight should choose carefully.
2. Chair leg and armrest design: Some chairs adopt a point-tube design where the chair legs and armrests are integrated. Even if the metal tubes are thin, the structure can enhance load-bearing capacity, and such a design is acceptable.
3. Mesh fabric material: Ordinary office chairs mostly use ordinary polyester mesh fabric, which has poor resilience. After being pressed, it is prone to leaving dents and is difficult to recover automatically, requiring manual smoothing. If durability is pursued, pay attention to the density and elasticity of the mesh fabric.
4. Adjustment functions:
   • Headrest: Prioritize headrests that can be adjusted back and forth to ensure neck support when sitting upright and reclining.
   • Lumbar support: An adaptive resilient lumbar support is better, as it can automatically adjust the support force according to posture changes.
   • Armrests: They should support at least three adjustments (up and down, forward and backward, rotation) to meet the height requirements of the arms in different scenarios.
5. Gas lift: Look for international certifications such as SGS, BIFMA, and TUV. Gas lifts of grade 4 or above are safer and more stable, avoiding the risk of explosion.
6. Durability: Refer to the evaluations of old users and focus on issues such as the resilience of the lumbar support, the collapse of the seat cushion, and the looseness of the adjustment joints to ensure long-term trouble-free use.

With a budget of over 400 yuan, consider ergonomic chairs Take the Jingdong Jingzao Z5 soft (the tested model is the Z9smart) as an example:

• Main frame: It uses a nylon frame, and the main frame of the backrest is thick, providing strong structural stability.
• Gas lift: It has passed the TUV grade 4 certification, ensuring high safety.
• Mesh fabric material: The chenille flocked mesh fabric is soft and has a cotton-like feel, combining breathability and comfort.
• Adjustment functions: The headrest has a 2D design (it can be raised and lowered by 7.6 cm and rotated by 30 degrees); the lumbar support is a conventional adaptive lumbar support; the armrests have a 3D soft-surface design (supporting up and down, forward and backward, and rotation adjustments); the chassis is a conventional mechanical chassis (a rocking chassis), and the lever control is convenient.

Summary: When the budget is limited, prioritize meeting the requirements of load-bearing capacity, safety, and basic adjustment functions; when the budget is sufficient, choose ergonomic chairs to improve comfort and durability.
