Luxian Office Chairs

The office furniture procurement project for the Luxian Comprehensive Archives includes two types of office chairs: chairperson chairs and sofas. Specific information is as follows:

1. Chairperson Chairs

• Brand and Model: The brand is Zhongge, and the model is ZG-2101.
• Specifications: The total height is 1050mm, with a seat height of 450mm; the total width is 685mm, with a seat width of 540mm; the total depth is 700mm, with a seat depth of 500mm (allowing for a ±1mm error). These parameters reflect ergonomic design, such as the reasonable range of seat depth and width to accommodate most user body types, ensuring comfort during prolonged sitting.
• Procurement Quantity and Price: A total of 9 chairs were purchased, with a unit price of 500 yuan. The low unit price may be related to standardized design or bulk procurement, making them suitable for public areas such as conference rooms.

2. Sofas

• Brand and Model: The brand is also Zhongge, and the model is ZG-2330.
• Specifications: Two size combinations are available: 2050mm (length) × 870mm (width) × 860mm (height, for 3-seater) and 1300mm (length) × 870mm (width) × 860mm (height, for 1-seater). This design can flexibly meet different spatial needs, such as reception areas or rest areas.
• Procurement Quantity and Price: A total of 1 sofa was purchased, with a unit price of 2700 yuan. The significantly higher unit price of the sofa compared to the chairperson chairs may be due to its larger size, more materials used (such as frame structure and filling density), or design complexity (such as modular combinations).

3. Procurement Background and Usage Speculation
As a public service institution, the Luxian Comprehensive Archives needs to balance functionality and budget control in its office furniture procurement. The bulk procurement of chairperson chairs indicates their use in high-frequency scenarios such as conference rooms, while the sofas may be used for receiving visitors or providing temporary rest spaces. The choice of the same brand (Zhongge) for both types of furniture may be due to considerations of unified style, ease of maintenance, or supplier negotiation advantages.

4. Parameter Rationality Analysis
The seat height (450mm) and seat depth (500mm) of the chairperson chairs comply with ergonomic standards, reducing fatigue during prolonged sitting. The size design of the sofas (such as the 3-seater length of 2050mm) can accommodate multiple people simultaneously, making them suitable for public areas. In terms of price, the unit price of 500 yuan for chairperson chairs is at a medium-low level among similar products, while the unit price of 2700 yuan for sofas may be higher due to differences in size and materials.
