PU Wheel Office Chair

The PU wheel office chair is characterized by its PU-material casters, offering features such as quiet operation, wear resistance, and floor protection, with a variety of types to meet different usage scenarios.

I. Typical Product Types

1. Henglin Counterattack II Ergonomic Chair: Equipped with PU silent wheels, suitable for home or nighttime use. Its core advantage lies in the PU material of the wheels, which produces noise below 30 decibels during rolling, preventing disturbance to others' rest. Additionally, the wheels are designed to reduce friction with the floor, enhancing smooth movement by over 40%.
2. Enjoy Chair (Jinzhuo Computer Chair): Fitted with PU casters, positioned as an office chair and home chair. The wheels use a high-elasticity PU formula, offering twice the wear resistance of ordinary rubber wheels and a lifespan of over 5 years. Moreover, the wheels are treated with an anti-slip surface, ensuring safety on wooden or tiled floors without slipping.

II. Characteristics of the Accessory Market

1. Size and Functional Diversity: PU casters range in size from 1.5 inches to 3 inches, accommodating different chair leg diameters. Functionally, they are divided into stem-mounted (directly inserted into the chair leg), swivel (360-degree rotation), and brake-equipped (fixed position) types, with price ranges from 1.52 yuan to 362 yuan. For example, a 2-inch brake-equipped swivel caster is more complex in structure and costs 30%-50% more than a standard model.
2. Material and Process Differences: High-end products use imported PU raw materials, molded in one piece through injection molding, ensuring uniform wheel density and an anti-tear strength of over 15 MPa. Low-end products often use recycled materials, prone to cracking or deformation. Some brands also add a carbon fiber coating to the wheel surface to further enhance wear resistance.

III. Suitable Scenarios and Advantages PU wheel office chairs are widely used in offices, home studies, gaming rooms, and other settings. Their core advantages include:

• Quiet Operation: The moderate hardness of PU material results in vibration frequencies during rolling that are below the human ear's sensitive range (20-20000 Hz), effectively reducing noise interference.
• Floor Protection: Compared to metal or hard plastic wheels, PU wheels are soft on the surface, preventing scratches on wooden or tiled floors, especially suitable for homes with underfloor heating.
• Smooth Movement: By optimizing the wheel hub bearing structure, PU wheels reduce starting resistance by 60% compared to traditional wheels when bearing 50 kg, making movement more effortless.
