Office Chair and Height

The height of an office chair should be precisely matched to one's height to ensure a healthy and comfortable sitting posture. Specific recommendations are as follows:

1. Extra-small stature (150-155cm)
Choose a model with a seat height of ≤45 centimeters to ensure that your feet are flat on the ground and your thighs are parallel to the ground when seated. If your legs are dangling, use a footrest to avoid obstructing blood circulation. The lowest position of the lumbar support should be ≤20 centimeters to precisely support the lower L3-L5 lumbar segments and reduce fatigue from prolonged sitting. For example, the Sihoo S100, launched in 2026, is optimized for small Asian body types, with the lumbar support able to descend to 18 centimeters from the seat cushion and a minimum seat depth of 42 centimeters, significantly enhancing comfort.

2. Standard short stature (155-165cm)
The recommended seat height is 45-50 centimeters, with a seat depth of 42-45 centimeters. The lumbar support should have a wide adjustment range to fit the lumbar curve. Recommended models include the Sihoo M15 and Hbada P2pro, designed to fit the physiological characteristics of this height range. When adjusting, ensure that you can easily fit your palm under your thighs when seated; if your feet do not reach the ground, use a footrest for support.

3. Standard height (165-180cm)
These individuals have greater versatility and should prioritize mid-to-high-end models with comprehensive adjustability, such as the ErgoHuman Plus E2 Pro. Pay attention to the multi-dimensional adjustment functions of the backrest, headrest, and armrests to accommodate different sitting positions. Men typically suit a seat height of 41-43 centimeters, while women suit 40-42 centimeters, but this should be based on individual leg length to avoid blindly imitating others' settings.

4. Tall stature (180cm and above)
Choose a model with a sufficiently high backrest and an adjustable headrest position, such as products with adjustable backrest height and a wide headrest adjustment range, to avoid neck suspension. When adjusting, ensure that the chair height forms a difference of 280-320 millimeters with the desk height to maintain a correct sitting posture and reduce spinal pressure.

Summary of Adjustment Points

• Feet on the ground: When seated, your feet should be firmly on the ground, and you should be able to easily fit your palm under your thighs; if your feet do not reach the ground, use a footrest.
• Gender differences: Men typically suit a seat height of 41-43 centimeters, while women suit 40-42 centimeters, but this should be based on individual leg length.
• Desk-chair difference: The chair height should be designed to form a difference of 280-320 millimeters with the desk height to maintain a correct sitting posture.
• Special designs: Small-stature users can prioritize optimized models with a low lumbar support position and a small seat depth, such as the Sihoo S100.
