Office Chair Foot Bracket

Office chair foot brackets come in a variety of types, with prices varying significantly due to factors such as material, design, and functionality. The following is a popular science introduction from three aspects: type, price, and installation for special chair types:

I. Common Types and Prices
Office chair foot brackets can be classified by the number of stars into three-star, four-star, and five-star feet, and by material into electroplated, aluminum alloy, wrought iron, etc.

• Electroplated Type: The electroplating process enhances corrosion resistance. Common models include electroplated five-star foot swivel chair brackets, priced at 42.0 yuan; electroplated boss chair base with five-star foot for office chairs, priced at 23.75 yuan; and thickened steel swivel chair foot with electroplating, priced at 20.0 yuan.
• Aluminum Alloy Type: Aluminum alloy material is lightweight yet strong. Examples include aluminum alloy die-cast five-star foot base for seats, priced at 130.0 yuan; cross four-star high aluminum alloy brackets, priced at 282.65 yuan; and aluminum alloy five-star foot chair base, priced at 262.3 yuan.
• Wrought Iron Type: Wrought iron brackets are usually structurally stable, such as wrought iron metal steel pipe chair brackets, priced at 392.5 yuan; and fixed four-star foot wrought iron model for office chairs, priced at 95.0 yuan.
• Special Design Type: Some brackets are designed for specific scenarios, such as the Baihe umbrella opening and closing five-star foot (mobile bracket for medical testing equipment), priced at 139.0 yuan; and foldable aluminum alloy brackets for corporate training rooms, priced at 190.0 yuan.

II. Factors Affecting Prices
Price differences are primarily determined by material, craftsmanship, and functionality. For example, the cost of electroplating is lower than that of aluminum alloy die-casting, so electroplated brackets are generally priced lower. Thickened designs and adjustable functions (such as height adjustment and rotation) increase costs. For instance, an aluminum alloy swivel chair base with height adjustment function costs 30.4 yuan, while a regular four-star bracket may only cost 57.0 yuan.

III. Installation Examples for Special Chair Types (Taking the w803 inclined foot chair as an example)

1. Foot Bracket and Crossbar Fixation: Place a gasket between the crossbar and the foot bracket, and secure it with four medium screws to ensure structural stability.
2. Armrest Installation: Complete in two steps - first, fix the armrest to the backrest with four short screws, then connect the armrest to the seat cushion with four medium screws to achieve a 90-degree rotation function.
3. Foot Bracket and Seat Cushion Connection: Fix the foot bracket to the bottom of the seat cushion with four elongated screws. After installation, sit on it to level it, then tighten the screws to avoid wobbling during use.
4. Headrest Installation: Fix the headrest with two short screws, supporting vertical rotation adjustment to meet different height requirements.
5. Function Adjustment: Rotate the button to adjust the seat height to adapt to different usage scenarios.

Purchase Recommendations: Choose materials and functions based on usage scenarios (such as office, medical, or training) and budget, paying attention to the load-bearing capacity and stability of the foot bracket. Follow the instruction manual strictly during installation to ensure safety in use.
