Office Chair Seat Extension

The Qingxian LiberNovo series of office chairs offers a 48cm extended seat, suitable for tall users over 175cm, enhancing comfort by expanding the seating area, optimizing leg support, and incorporating a dynamic lumbar support system.

Seat Extension Design: Core Optimization for Tall Users

The LiberNovo series introduces a 48cm extended seat for users over 175cm in height, increasing the length by approximately 10%-15% compared to standard office chair seats. This design expands the seating contact area, ensuring fuller contact between the back of the thighs and the seat, preventing issues such as leg suspension or impaired blood circulation due to a short seat. The extended seat is particularly suitable for prolonged office work or sedentary scenarios, reducing fatigue caused by insufficient leg support.

Dynamic Support System: Key Technology for Lumbar Comfort

This series of office chairs is equipped with a dynamic support system, allowing the backrest to automatically adjust its angle based on the user's movements (typically supporting 110°-135° recline adjustment). For example, when the user leans forward to work, the backrest slightly moves forward to provide close support; when reclining for rest, the backrest synchronously reclines while maintaining lumbar support. This function is achieved through mechanical structures or gravity sensing technology, effectively dispersing lumbar pressure and reducing the risk of lumbar muscle strain caused by prolonged sitting.

One-Size-Fits-All Backrest Adaptation System: Breakthrough in Personalized Support

The extended seat of the LiberNovo OC1 model adopts a 'One-Size-Fits-All Backrest Adaptation System,' with its backrest composed of eight flexible modules. Each module can be independently fine-tuned in angle (typically supporting ±5° adjustment), forming a support surface that closely fits the user's spinal curve through coordinated movement between modules. This design breaks away from the 'one-size-fits-all' support mode of traditional office chairs, particularly suitable for users with scoliosis or significant body shape differences, reducing shoulder and neck stiffness caused by an uncomfortable backrest.

Suitable Scenarios and User Groups

The combination of the extended seat and dynamic support system makes it an ideal choice for programmers, designers, and others who need to work at a desk for extended periods. Additionally, the 48cm seat length accommodates users ranging from 175cm to 190cm in height, preventing tall individuals from being forced into a crouched sitting posture due to a short seat. For users with lumbar conditions or those seeking ultimate comfort, the modular backrest design of the OC1 model further provides personalized support solutions.
