Intelligent Height-Adjustable Office Chair

The JD Jingzao Z5 Pro ergonomic chair is a fully functional intelligent height-adjustable office chair designed with both ergonomics and intelligent adjustments in mind, making it suitable for long hours of office work or rest.

Core Function Analysis

1. Dual-Back Design and Intelligent Adjustment This chair features an upgraded spine-supporting dual-back structure with a lumbar support that allows for 20° flexible rotation and offers three levels of lumbar support modes. Users can select the appropriate level based on their sitting posture (upright or reclined). The wide lumbar support not only supports the lumbar spine but also protects the sacral region, reducing fatigue from prolonged sitting. This design dynamically fits the spinal curve, dispersing pressure on the lower back, making it particularly suitable for office scenarios that require frequent sitting posture adjustments.

2. Height-Adjustable Backrest and Optimized Seat Cushion The backrest supports 50mm height adjustment, allowing users to precisely position their comfort zone based on their height or support needs. The seat cushion is made of 10.5cm thick, high-elastic material, designed with scientific pressure relief to fit the contours of the buttocks, avoiding localized pressure concentration. This balanced configuration of thickness and elasticity provides sufficient support while alleviating issues related to poor blood circulation caused by prolonged sitting.

3. Neck Pillow and Armrest Synergistic Design Equipped with a 2D large-arc neck pillow, the angle can be adjusted to meet the neck support needs of users of different heights. The wide armrest design allows the arms to relax naturally, reducing tension in the shoulder and neck muscles. The combination of the neck pillow and armrests creates a complete support chain from the neck to the arms, making it especially suitable for users who need to work at a desk or use a keyboard and mouse for extended periods.

4. Large Recline Angle and Safety Features The chair supports a 140-degree recline adjustment, meeting the needs of both daily office work and午休 (noon breaks), achieving a “one-chair-multiple-uses” function. In terms of safety, it uses a Class 4 gas lift that has passed international safety certifications, ensuring stable load-bearing and high durability, avoiding safety hazards such as gas lift explosions.
