Pre-shift Office Chair

The pre-shift chair is a supporting tool within the classification system of office chairs, belonging to the same category as executive chairs and mid-back chairs. It is primarily used in reception or meeting scenarios and is placed in front of executive desks.

Design and Structural Features

The design of pre-shift chairs emphasizes a combination of functionality and ergonomics. Their frame types are divided into two categories: solid wood and steel. Solid wood frames often use natural wood, providing a warm and textured feel; steel frames, on the other hand, enhance durability through metal electroplating processes. The electroplated layer must pass salt spray tests, with both corrosion resistance and protection ratings reaching level 10, ensuring long-term use without rusting.

In terms of fabric selection, pre-shift chairs commonly use cowhide or PU leather, with some high-end models featuring genuine leather materials. These are paired with high-density foam cushions to provide more comfortable support. The backrest design follows the contours of the human body, incorporating solid wood armrests, concave thickened cushions, and extra-wide backrests, effectively relieving arm fatigue and supporting the natural posture of the lumbar spine. Some models also introduce mechanical swivel functionality, enabling 360-degree automatic return for enhanced convenience.

Material and Process Standards

The production process of pre-shift chairs strictly adheres to a quality monitoring system:

• Raw Material Inspection: Key materials (such as wood, metal, and leather) must undergo composition analysis and strength testing to ensure compliance with environmental and safety standards.
• Semi-finished Product Inspection: Processes like frame welding, electroplating, and fabric cutting require checks for flatness, firmness, and surface defects.
• Finished Product Testing: Finished products must pass load-bearing tests (e.g., static load capacity ≥ 150 kg) and abrasion resistance tests (fabric friction count ≥ 5,000 times) to ensure durability.

Market Price and Model Variations

The price of pre-shift chairs varies based on materials, functionality, and brand:

• Basic Models: For example, the Xipi office chair from Foshan Fangsheng Furniture Co., Ltd. has a wholesale price of approximately 380 yuan, suitable for budget-conscious scenarios.
• Mid-to-High-End Models: The genuine leather pre-shift chair from Shanghai Xingman Furniture Co., Ltd. is priced at around 379.5 yuan, offering superior texture with genuine leather materials.
• Multi-functional Models: The modern office chair (including pre-shift chairs) from Foshan Nanhai Xiangyi Furniture Manufacturing Co., Ltd. is priced at approximately 580 yuan, featuring height adjustment and rotation functions, ideal for executive offices or high-end meeting rooms.

Some models are also optimized for specific needs, such as lumbar protrusion support and bow-shaped chair legs, further aligning with ergonomic requirements.
