Office Chair Casters

"Office chair casters" typically refer to the wheels (casters) of an office chair, whose core function is to provide mobility convenience. They come in a variety of materials and designs, with a wide price range.

1. Types and Functions of Casters
   Office chair casters are mostly designed as swivel casters, allowing 360-degree rotation for flexible movement without leaving the seat. Common materials include PVC, PU, and nylon, each with distinct characteristics:

• PU casters: Offer excellent noise reduction, suitable for wooden floors or noise-sensitive environments;
• Nylon casters: Highly wear-resistant with strong load-bearing capacity, ideal for carpets or rough surfaces;
• PVC casters: Cost-effective but relatively weaker in terms of wear resistance and noise reduction.
  Some casters also feature brake functions (such as snap-ring casters) or shock absorption designs to meet specific scenario requirements.

2. Price and Sales Volume
   The price of casters varies based on material and function. For example:

• 2-inch transparent PU casters: Priced at approximately ¥5.32 each, with a monthly sales volume of 4,101 units, suitable for users seeking noise reduction and aesthetics;
• Noise-reducing swivel casters: Priced at approximately ¥2.0 each, with a monthly sales volume of 7,700 units, offering high cost-performance for daily office use;
• Snap-ring casters with brake functions: Priced at approximately ¥4.0 each, with a monthly sales volume of 14 units, suitable for scenarios requiring fixed positions.
  Prices range from ¥0.5 to ¥200, allowing users to choose based on their budget and needs.

3. Other Possible Components: Gas Lift
   If "casters" refer to the cylindrical structure beneath the office chair, it is typically a gas lift. Its function is to adjust the chair's height by compressing or releasing high-pressure nitrogen, with some models also allowing adjustment of the backrest's recline tension. The gas lift is not directly related to the casters but together forms the core functional modules of the office chair.

4. Design Background and Applicable Scenarios
   The design of office chair casters stems from the need for efficiency in modern offices, allowing users to move without leaving their seats to accommodate the expansion of clerical work and larger desks. For example, in open office environments, noise-reducing casters can minimize noise interference; in scenarios requiring frequent movement, wear-resistant casters can extend service life.

Summary: If "casters" refer to the wheels, it is recommended to choose the appropriate type based on noise reduction, load-bearing capacity, and price requirements; if referring to the gas lift, attention should be paid to its lifting function and safety.
