Extended Backrest Office Chair

The representative product of extended backrest office chairs is the LiberNovo brand's Relax Dynamic Ergonomic Computer Chair. Its 48cm extended version design offers significant advantages in functionality and user experience, with the following specific features:

1. Shipped Fully Assembled, Ready to Use Out of the Box

This product adopts a fully assembled shipping model, eliminating the need for users to assemble it themselves. The chair has undergone all installation steps at the factory, and users can simply pull it out of the packaging box and start using it immediately upon unboxing. This design greatly simplifies the usage process, especially for users unfamiliar with assembly tools or operations, while also avoiding the risk of structural instability caused by self-assembly, ensuring a seamless transition from delivery to use.

2. Ergonomic Design: Optimized Back and Lumbar Support

• Backrest 'One-Size-Fits-All Adaptive System': The backrest appears as a complete panel from the front but is composed of eight flexible modules on the back. Compared to the traditional 'two-piece structure' of ergonomic chairs, this design can more delicately conform to the back curves of different users through the independent deformation of the modules, providing dynamic support. For example, when a user leans back, the modules automatically adjust according to the pressure distribution, reducing localized pressure and enhancing the technological aesthetic.
• Soft Lumbar Support Design: The lumbar area is filled with high-density foam, forming a soft and elastic support surface. This design not only alleviates lumbar fatigue caused by prolonged sitting but also avoids the issue of poor blood circulation that may result from traditional rigid supports, making it suitable for users who need to work at a desk for extended periods.

3. Functional Features: Electric Assist and Angle Adjustment

• Electric Assist Push Rod and Massage Function: Three adjustment buttons are integrated on the inner side of the left armrest. The front and back buttons control the backrest support angle, while the third button activates the massage function. When turned on, the backrest simulates massage movements through up-and-down mechanical motion, with a strong intensity that effectively stretches the spine and relaxes the back muscles. This feature is relatively rare among similar products and is particularly suitable for office scenarios where muscle tension needs to be relieved.
• Four-Level Angle Adjustment and 160-Degree Recline: The chair supports four-level angle adjustment, with a maximum recline angle of 160 degrees, far exceeding that of mainstream high-end ergonomic chairs in China (140-150 degrees). This design allows users to almost lie flat when resting, approaching a sleeping position, further reducing physical stress.
• Type-C Charging Support: The built-in battery can be charged via a Type-C port, compatible with charging cables for mainstream electronic devices, eliminating the need for an additional dedicated charger and enhancing usage convenience.

This product meets the dual demands for comfort and functionality in office scenarios through its extended design, dynamic support, and intelligent features, making it especially suitable for user groups pursuing efficient work and a healthy experience.
