Deli Office Chair Fixed Design
The fixed design of Deli office chairs is mainly reflected in the headrest, lumbar support, and installation structure, with the following specific features:
Fixed Headrest Design
Some models of Deli office chairs, such as gaming chairs and ergonomic chair series, feature a fixed headrest. Its core characteristic is that it only supports vertical height adjustment and cannot be rotated or moved forward or backward. This design achieves fixation through preset buckles or slide rail structures, simplifying the adjustment process but having limited compatibility with height differences. For example, users under 170cm in height may not receive effective support due to insufficient headrest height, while users over 185cm may experience neck suspension due to the low position of the headrest.
Fixed Lumbar Support Function
The lumbar support design of Deli ergonomic chairs emphasizes structured fixed support. Taking the Surfer series as an example, it adopts 3D lumbar support technology, achieving dynamic fit through the combination of an elastic frame and ergonomic curves. This lumbar support is not completely fixed but automatically adjusts its fit through preset support angles and elastic materials as the user's sitting posture changes. This design avoids the stiffness of traditional fixed lumbar supports while maintaining the stability of the core support structure. It is particularly suitable for users who need to maintain correct sitting posture for long periods, effectively dispersing lumbar pressure.
Fixed Structure During Installation
During the assembly process, Deli office chairs ensure structural stability through screw fixation and alignment indicators. For example, the connection between the seat and the base requires the use of special screws to lock tightly, preventing looseness during use. Some models feature positioning protrusions and grooves at the joint between the backrest and the seat cushion, which, combined with the indicator arrows in the installation instructions, allow for quick alignment of components and reduce shaking problems caused by installation errors. Additionally, the connection between the five-star base and the pneumatic rod usually adopts a dual-locking mechanism, further enhancing overall stability.
Applicable Scenarios and Limitations of Fixed Design
Fixed headrests are suitable for office environments with a concentrated height range (such as standard desk heights), while the fixed support structure of the lumbar support is more suitable for users who need to maintain correct sitting posture for long periods (such as programmers and designers). However, the limitation of fixed design lies in its lack of flexibility. For example, the headrest cannot adapt to multi-angle usage needs, and the support intensity of the lumbar support may vary due to weight differences, resulting in different user experiences. Users need to choose models based on their own needs or optimize comfort by adding adjustable accessories (such as external lumbar pads).
