Office Chair with Double-Layer Backrest
Office chairs with double-layer backrest designs include the JD.COM Jingzao Z5 Pro Ergonomic Chair, Lianfeng E-50 Computer Chair, and Yongyi M60 Second-Generation Ergonomic Chair, among others. Here is a detailed introduction:
JD.COM Jingzao Z5 Pro Ergonomic Chair: It features an upgraded spine-protecting large double-back design, which is a prominent highlight. The 20ยฐ flexible rotating lumbar support combined with a 3-level lumbar support mode can meet the needs of different users for lumbar support intensity. The wide lumbar support plays a significant role. It not only provides precise lumbar support when sitting upright, helping to keep the waist in the correct posture and reducing fatigue caused by prolonged sitting; it also fits snugly against the waist when leaning back, providing all-around protection for the waist and also protecting the sacrum, effectively reducing sacral pressure. It is suitable for people who work for long hours.
Lianfeng E-50 Computer Chair: The double-backrest design of this chair is unique. It cleverly disperses the force-bearing areas. This design makes it easier for users to find a comfortable area during use, enhancing the comfort of the sitting experience. It supports 3cm of front-to-back adjustment, allowing users to flexibly adjust the front-to-back position of the backrest according to their physical condition and sitting habits to find the most suitable support point. It also has the ability to float 15ยฐ left and right, better adapting to the waist movements of the human body in different postures. In addition, the automatic waist-following effect is a major advantage. No matter how the user moves their body, the backrest can automatically follow the waist and continuously provide effective support.
Yongyi M60 Second-Generation Ergonomic Chair: It adopts a dynamic-fitting large double-back design, with the backrest divided into zones to fit the physiological curve of the waist and back. This is one of its core advantages. This fitting design can better adapt to the natural shape of the human waist and back, reducing the gap between the waist and back and the backrest, and providing more uniform support force. The 2D zone-adjustable lumbar support further enhances its adaptability. Users can adjust the lumbar support horizontally and vertically according to their needs, ensuring that the waist is fully supported regardless of the sitting posture, effectively relieving waist fatigue caused by prolonged sitting and allowing users to sit for long periods without feeling tired.
