405 Office Chair
The '405 Office Chair' is not a single standard product. Currently, there are two clearly associated models: 'Bajiujian 405zb Black' and 'Heibaidiao X7 (with the '405 Energy' label)', which differ significantly in functional orientation and applicable scenarios.

1. Bajiujian 405zb Black: Home Bow Chair, Focusing on Basic Comfort
This model belongs to the Bajiujian brand and is positioned as a home bow chair. It incorporates ergonomic elements in its design and supports a reclining function, making it suitable for gaming leisure or home office scenarios. Its core features include:
- Structural Stability: It features a bow-shaped chair foot design without casters, suitable for fixed-position use, reducing the need for movement;
- Reclining Function: The chair back supports multi-angle adjustment to meet the need for short rests;
- Material and Comfort: It is usually equipped with a high-density foam seat cushion and a breathable mesh backrest, balancing support and breathability.
It should be noted that this model does not emphasize smart functions or complex adjustment systems, making it more suitable for users with a limited budget who seek basic comfort.
2. Heibaidiao X7 (with the '405 Energy' label): High-End Smart Chair, Focusing on Health Management
The Heibaidiao X7 is a high-end smart ergonomic chair. Although the specific meaning of '405 Energy' in the model name is unclear, its functional configuration is significantly superior to that of traditional office chairs:
- Smart Sensing System: It is equipped with built-in pressure sensors in the seat cushion and lumbar support, which can monitor the distribution of sitting posture pressure in real-time and assist users in adjusting their posture;
- Active Lumbar Tracking Technology: The lumbar support can automatically track the position of the user's waist according to their movements, providing dynamic support;
- Sedentary Reminder and Massage: Through timed reminders and automatic massage functions, it relieves sedentary fatigue and reduces health risks;
- Multi-Dimensional Adjustment: It supports independent adjustment of components such as the headrest, armrests, and chair back to accommodate different body types and usage scenarios.
This model is suitable for users who work long hours or have high demands for health management, but its price may be relatively high.
Other Considerations
Currently, no other office chair models named '405' have been found in publicly available information. If users need to learn more about specific parameters (such as dimensions, materials, weight capacity, etc.), it is recommended to contact the brand directly or consult the product manual. Additionally, when purchasing, pay attention to distinguishing model suffixes (such as 'zb Black' and 'Energy') to avoid misselection due to naming differences.
