Office Chair Base
The bases of office chairs mainly fall into two types: mechanical bases and cable-controlled bases, with differences in functionality, price, and applicable scenarios.

In terms of type classification, mechanical and cable-controlled bases are the two mainstream designs currently. Mechanical bases achieve functional adjustments through physical structures, such as reclining locking and height adjustment. Their advantages lie in structural stability and strong durability, but operation may require a certain amount of force. Cable-controlled bases, on the other hand, achieve functional adjustments through a cable control system, offering more convenient operation, such as adjusting the reclining angle with one hand, but at a relatively higher cost.
Regarding functional characteristics, the design of the base directly affects the comfort and practicality of the office chair. Taking the Sihoo C500 second generation as an example, its base adopts a flagship-level design, providing a smooth reclining experience that can be locked, making it suitable for use during lunch breaks after work. The backrest of this base is designed with two tracks, and the main lifting and gliding function can adjust the follow-back experience according to the user's height, with the support effect becoming more pronounced as height increases. Additionally, during the lifting process, the headrest and lumbar support synchronize and dynamically adjust the position of the lumbosacral support, effectively relieving fatigue from prolonged sitting. Such designs are typically found in mid-to-high-end office chairs, emphasizing ergonomics and scenario adaptability.
In terms of price differences, the material and craftsmanship of the base are the main influencing factors. Aluminum alloy bases, known for their high strength and light weight, generally cost over 40 yuan, such as the aluminum alloy tray accessories sold directly by a manufacturer for 47 yuan. Ordinary steel bases have lower costs, with electroplated five-star footrest bases priced at approximately 13.16 yuan. Meanwhile, cable-controlled bases or butterfly plate designs with multi-functional adjustments may cost over 50 yuan. Consumers can choose the appropriate type based on their budget and needs.
It should be noted that as a core component of office chairs, the base needs to work in conjunction with other components such as gas rods and chair feet. For example, executive chairs, as a็ปๅๅ็ฑป (subcategory) of computer chairs, require their bases to cooperate with gas rods for height adjustment while meeting the support needs of the waist and head. In terms of material selection, they tend to favor leather or mesh to enhance comfort.
