Office Chair Seat Extension

Admin October 12, 2026

The Qingxian LiberNovo Omni dynamic ergonomic office chair features a seat extension design, with its 48cm extended version meeting the needs of specific users. The key features are as follows:

1. Extended Design for Tall Users or Those Preferring Deep Seating
The 48cm extended version of this chair extends the seat depth, providing ample leg support for taller users or those who prefer a deeper seating position. The design that supports the entire thigh prevents the issue of suspension caused by insufficient length in traditional chairs, reducing the risk of poor blood circulation due to localized pressure concentration, making it particularly suitable for long hours of office work or prolonged sitting.

2. Dynamic Support Structure Enhances Fit
The backrest behind the seat is composed of eight flexible modules. The modular design allows it to dynamically adjust the support angle according to the user's sitting posture. For example, when the user leans back, the backrest modules distribute pressure to key areas such as the shoulder blades and lumbar spine, preventing excessive stress on a single area; when sitting upright, it provides uniform support, reducing fatigue from prolonged sitting.

3. Multi-Angle Recline Function Meets Scenario-Based Needs
The chair supports a maximum recline of 160 degrees and comes with preset common angles such as 135ยฐ and 105ยฐ. The 160-degree angle, close to lying flat, is ideal for lunch breaks or short rests, while 135ยฐ and 105ยฐ can be used for reading, meetings, and other scenarios, allowing users to quickly switch states without repeated adjustments. Additionally, the recline function is usually paired with a synchronous tilt mechanism to ensure that the seat and backrest angles move in tandem, preventing the 'foot-lifting' phenomenon.

4. Ergonomic Design Optimizes Health Experience
The combination of an extended seat and a dynamic backrest essentially applies ergonomic principles. By extending the seat depth, users can naturally sit closer to the backrest, reducing lumbar pressure caused by leaning forward; the modular backrest, by dispersing pressure points, reduces muscle fatigue. These designs collectively enhance sitting health, especially suitable for office workers who need to maintain focus for extended periods.

Please note that the seat extension design may have certain space requirements, and users should choose the appropriate version based on their usage environment.
