Discomfort from Sitting in Office Chairs
Discomfort from sitting in office chairs is primarily caused by design flaws, material issues, and functional degradation. The specific reasons are as follows:

1. Insufficient support due to design flaws
Ordinary office chairs with straight or overly soft backrests fail to conform to the natural lordotic curve of the human lumbar spine, causing the waist muscles to continuously exert effort to maintain posture. Prolonged maintenance of this state leads to muscle stiffness from excessive fatigue, resulting in soreness. Additionally, chairs lacking height and depth adjustment functions have poor adaptability, providing support to less than 30% of users of different heights. For example, taller users may experience a lack of effective support due to insufficient seat height, leaving their waists suspended; shorter users may have their legs suspended due to excessive seat depth, forcing the pelvis to tilt backward and increasing lumbar pressure.
2. Material selection affects physical comfort
The material of the seat directly impacts its temperature regulation ability during use. Cheap synthetic leather has poor breathability, causing heat to accumulate at the contact points between the skin and the seat surface in summer, leading to stuffiness and discomfort; tightly woven fabrics, while more breathable, have fast heat conduction rates, potentially making users feel cold in winter due to rapid heat dissipation. Furthermore, some materials with insufficient surface friction may cause the body to slide, further disrupting proper sitting posture and indirectly leading to fatigue.
3. Functional degradation reduces user experience
After prolonged use, key components of the seat may experience degradation. For example, collapsed cushion fillings can lead to uneven pressure distribution on the buttocks, increasing localizedๅ่ฟซๆ (pressure sensation); weakened backrest elasticity fails to provide continuous support, forcing the waist muscles to remain tense. If the seat lacks adjustability (such as armrest height and tilt angle), users may be forced to maintain poor posture due to the inability to adjust to a comfortable position, accelerating fatigue accumulation.
Improvement suggestions: Choose seats designed according to ergonomic principles, prioritizing products with adjustable height, depth, backrest tilt, and lumbar support functions; for materials, opt for breathable mesh or breathable leather; regularly inspect the seat's condition and promptly replace collapsed cushions or components with insufficient elasticity to maintain long-term comfort.
