Office Chair Accessories Base
There are various types of office chair accessories bases, and prices vary significantly depending on the material and functionality. For executive chair bases, it is essential to focus on the material and safety of core components such as the five-star base, tray, wheels, and gas lift cylinder. Here is a detailed analysis:
1. Five-Star Base Material and Price
The five-star base is the core support component of the chair base, directly affecting the chair's stability. Most ordinary office chairs use electroplated steel five-star bases, which are relatively inexpensive (e.g., ยฅ14.5-ยฅ58.0) and suitable for daily office settings. Executive chairs can be upgraded to solid wood five-star bases, which can cost up to ยฅ259, offering both stability and aesthetics. However, it is advisable to avoid plastic materials (which are prone to breakage and have a short lifespan). Some high-end products use aluminum alloy or thickened alloy electroplating processes (e.g., an aluminum alloy five-star base for ยฅ147.25), further enhancing load-bearing capacity and durability.
2. Tray Material and Safety Design
The tray is a key component connecting the seat to the gas lift cylinder, responsible for bearing the weight of the user and transmitting the lifting force. High-quality trays are typically made of aluminum alloy (priced between ยฅ6-ยฅ50). It is recommended to choose a design with an explosion-proof steel plate to prevent shrapnel from flying in the event of an accidental explosion of the gas lift cylinder, enhancing safety. Some low-end products use ordinary steel plates or plastic trays, which are prone to deformation over long-term use and should be chosen with caution.
3. Wheel Types and Suitable Scenarios
The material of the wheels directly affects smooth movement and noise control. Nylon wheels are inexpensive but prone to hair entanglement and are suitable for smooth floors. Metal wheels (such as those with a silent rubber coating) are more expensive but offer smoother rolling and are suitable for hard floors. If the office has carpeted floors, it is necessary to choose large wheels with brake functions (such as thickened steel wheels) to prevent the chair from sliding or scratching the floor.
4. Gas Lift Cylinder Certification and Safety
The gas lift cylinder is the core component for adjusting the chair's height. It is essential to look for the BIFMA certification (American National Standards Institute for Office Furniture) to ensure it has undergone durability testing and explosion-proof treatment. Poor-quality gas lift cylinders may pose risks of air leakage or explosion, so it is advisable to prioritize products that have passed international certifications when making a purchase.
5. Other Accessory Considerations
Small connecting parts (such as screws and nuts) should be regularly inspected and tightened to prevent loosening that could cause the chair to wobble. If the base is equipped with a height adjustment function, it is necessary to confirm the durability of the adjustment handle (metal materials are superior to plastic). Additionally, executive chair bases can incorporate a tilt-lock function (achieved through the tray or gas lift cylinder) to enhance user comfort.
