Black Spots of Office Chairs

The “black spots” (obvious drawbacks) of office chairs mainly focus on design flaws, durability issues, and high-price controversies, with specific manifestations as follows:

1. Design flaws of the Sihoo M57

• Unstable head adjustment: When the backrest is adjusted to its highest position, the headrest cannot stably support the neck, especially in scenarios like looking straight ahead or taking a nap, where the head is prone to shifting, resulting in loss of support.
• Insufficient backrest tilt angle: The minimum tilt angle is not low enough, limiting body stretching during naps and affecting comfort.
• Safety hazard of 3D armrests: The armrests can slide easily with slight force during forward-backward adjustment and rotation as there are no buckles for fixation. Some users have nearly fallen due to armrest displacement.
• Non-ergonomic operation: Adjusting the chair height requires pressing down on a lever with the thumb, which can easily cause finger fatigue with long-term use.
• Lack of footrest design: Not user-friendly for those who need to lift their feet to relax, such as long-sitting office workers.

2. General design durability issues

• Deformation with long-term use: The seat cushions of some chairs are prone to collapse after prolonged sitting due to filler aging or structural problems; the mesh fabric may become loose, affecting support.
• Loose components and abnormal noises: Components such as armrests and chair wheels may wobble after long-term use, and noise may occur due to structural friction when leaning back.
• Ineffective lumbar support: Initially, the lumbar support is in an appropriate position, but after prolonged sitting, due to body movement or difficulty in adjustment, the sense of support weakens or even disappears.

3. Cost-effectiveness controversies of high-priced products

• Questioning the premium of the Herman Miller Aeron: As a classic high-end model priced at 15,000 yuan, some users believe that its actual support effect is not significantly different from that of mid-range products and question the rationality of the brand premium.
• Mismatch between functions and price: The additional functions of high-priced chairs (such as multi-angle adjustment and material upgrades) may not significantly enhance the core experience, leading to user dissatisfaction with the return on investment.

Other considerations
Although some models (such as the Jingdong Jingzao Z7 and SumLush Xia Muwu Fit CC) do not explicitly mention significant drawbacks, it is necessary to pay attention to long-term use evaluations, especially potential issues such as mesh durability and gas lift safety. It is recommended to refer to multi-dimensional evaluations before purchase and choose a suitable model based on personal needs (such as height, weight, and usage scenarios).
