Office Chair Swivel Base

The office chair swivel base is the core component that enables a swivel chair to adjust its height and rotate. There are significant differences in its materials, functions, and prices, so when purchasing, it is essential to focus on material strength, functional adaptability, and compatibility.

Core Functions and Structure

The office chair swivel base achieves height adjustment through a gas lift and supports 360-degree rotation of the seat through a swivel mechanism. Some high-end products (such as the Woshitianc Ultra Ergonomic Chair) use a DONATI base, which integrates more complex mechanical structures to enhance stability; the Tiankuang A1Pro is upgraded with a cable-controlled butterfly plate, adding adjustable recline positions to meet the needs of various scenarios.

Material and Price Differences

The material of the base directly affects its durability and cost:

• Ordinary Butterfly Plate: Mostly made of steel or basic alloys, paired with plastic accessories, priced at approximately 18 yuan, suitable for basic office settings.
• Aluminum Alloy Tray: Lightweight and strong, priced at around 47 yuan, commonly found in mid-to-high-end ergonomic chairs.
• Thickened Electroplated Five-Star Foot Base: Prices vary widely (13.16 yuan to 53.2 yuan), with electroplating improving rust resistance, suitable for humid environments.
• Custom Hairdressing Chair Electroplated Base: Due to the need to support greater weight and frequent adjustments, prices can reach as high as 416 yuan, using thickened steel and special coatings.

Key Points for Selection

1. Material Strength: Prioritize aluminum alloy or thickened steel bases to avoid deformation after long-term use; if on a budget, confirm the load-bearing standard of ordinary steel bases (usually ≥100kg).
2. Functional Adaptability:
   • When recline functionality is needed, choose a cable-controlled base with adjustable positions (such as the Tiankuang A1Pro);
   • For frequent height adjustments, ensure the quality of the gas lift (preferably those certified by SGS).
3. Compatibility: Measure the mounting hole spacing of the chair (commonly 28cm × 28cm) to confirm that the base size matches; for special scenarios like hairdressing chairs, a custom base may be needed to fit an enlarged seat.

Precautions

Avoid choosing bases with excessively low prices (such as ordinary models below 15 yuan), as they may pose safety risks like gas lift leakage or swivel mechanism jamming; for high-end custom bases, verify the supplier's qualifications to prevent cost overruns due to over-engineering.
