Specifications and Models of Office Chair Five-Star Bases
Admin October 08, 2026
The specifications and models of office chair five-star bases vary depending on the product type and usage scenario, with a common diameter range of 600mm to 700mm, which can be specifically divided into general specifications and special products.

General Diameter Specifications
- Ordinary Office Chairs: Typically, they are compatible with five-star bases with a diameter of around 600mm. This specification can meet the load-bearing requirements of daily office scenarios. For example, regular office chairs have relatively small seat sizes, and a 600mm diameter can balance stability and material costs while fitting the floor space of most office environments.
- Executive or Managerial Chairs: Due to their larger seat sizes and higher load-bearing requirements, they generally use five-star bases with a diameter of around 700mm. For instance, managerial chairs need to support heavier weights and have a high frequency of use. A 700mm diameter can expand the support area, enhance the overall structural stability, and avoid the risk of tipping due to a shift in the center of gravity.
Examples of Special Product Sizes
- Xiyan 283032 Caster-Compatible Five-Star Base Frame: It has dimensions of length 4.9 cm ร width 4.9 cm ร height 7.8 cm and is usually used for lightweight office chairs or specific models of caster components. Such small five-star bases reduce weight by shrinking in size, making them suitable for scenarios that require high mobility flexibility, but their load-bearing capacity is relatively limited.
- Widened and Thickened Nylon Five-Star Base Frame: Although its specific dimensions are not clearly marked, it improves load-bearing performance through a โwidened and thickenedโ design, making it suitable for scenarios with heavier weights or long-term high-load use. Its diameter may be close to or slightly exceed 700mm. For example, some industrial office chairs disperse pressure by increasing the width of the base frame to ensure stability under heavy loads.
Other Common Models
Zhejiang Anji Kaixin Furniture Co., Ltd. offers a variety of five-star base models, such as:
- KX-300-002 Bread-Shaped Base: Its design focuses on stable load-bearing and is suitable for scenarios with high structural strength requirements.
- KX-320-003 Disassemblable Base: It optimizes logistics costs through a modular disassembly design, facilitating transportation and assembly.
- KX-340-001 German Flat Base: It adopts a flat design, balancing stability and space utilization.
When choosing a five-star base, it is necessary to comprehensively consider the seat type, usage scenario, and load-bearing requirements to ensure a balance between safety and functionality.
