The brand of office chairs purchased by Yan'an Ansai District Senior High School is 'Hualilong', with the model number A-1448, supplied by Shaanxi Chengyuantongjiu Trading Co., Ltd. through winning the bid, but no specific installation information was provided. The following provides an explanation from three aspects: procurement background, product information, and installation precautions:

Procurement Background and Supplier Information

The procurement project for office desks and chairs at Yan'an Ansai District Education and Sports Bureau Senior High School determined the supplier through open bidding. Eventually, Shaanxi Chengyuantongjiu Trading Co., Ltd. won the bid, with a winning bid amount of 475,800.00 yuan. The procurement target clearly included office desks and chairs of the 'Hualilong' brand with the model number A-1448, but did not involve office chairs of other brands or models.

Product Information and Specifications

The specific parameters of the 'Hualilong' A-1448 model office chair have not been disclosed in detail in public information. However, based on similar products, it is speculated that its design may meet the needs of educational settings, for example:

• Material: The seat may use breathable mesh fabric or wear-resistant leather, and the backrest is ergonomically designed to support the waist;
• Structure: A five-claw metal base with silent wheels ensures stability and ease of movement;
• Adjustment Functions: It may be equipped with functions such as height adjustment and armrest adjustment to accommodate users of different heights.
  It should be noted that the actual product characteristics should be based on the procurement contract or technical documents provided by the supplier.

Installation Precautions

Although the reference information does not directly involve the installation process, the installation of office chairs generally needs to follow the following general principles:

1. Tool Preparation: Basic tools such as screwdrivers and wrenches are required, and some models may require special hex wrenches;
2. Component Inspection: Check the parts list before installation to ensure that components such as screws, wheels, and backrests are complete and undamaged;
3. Standardized Steps: Install the base and wheels first, then secure the seat, and finally connect the backrest and armrests to avoid structural damage caused by forced assembly;
4. Safety Testing: After installation, check the tightness of the screws and test whether functions such as height adjustment and rotation are normal to ensure there is no looseness or abnormal noise.
   If users need specific installation instructions, it is recommended to contact the supplier or refer to the product manual.
