Computer Chair and Office Chair Chassis

There are various types of chassis for computer chairs and office chairs, with different designs and components each having their own characteristics.

Chassis Designs of Common Brand Chairs

• Jingzao Z5 Pro: It features a single torsion spring chassis with two control levers, offering clear functions and easy operation. One lever is responsible for adjusting the height of the seat cushion, allowing users to easily set it to a comfortable height based on their own height and usage needs, ensuring a comfortable sitting posture. The other lever controls the recline function, meeting users' needs for adjusting the chair angle in different scenarios, such as resting or thinking. However, this chassis lacks伸缩度 (this term might be a bit unclear in English context, if it means 'adjustable depth', it can be translated as 'adjustable depth'), and the recline resistance cannot be adjusted, which somewhat limits the flexibility of chair adjustments for users.
• enova Learning School and Jingzao Z7 Comfort Second Generation: These two chairs have similar chassis designs. The backrest is connected to the seat cushion and locked with screws. This design makes the connection between the backrest and the seat cushion relatively stable, but the chassis has no springs. The lack of springs may result in relatively weak performance in cushioning and shock absorption. When users sit down or stand up, they may not experience a smooth transition like with a chassis that has springs.

Office Chair Chassis Components on the Market

• Aluminum Alloy Tray: Aluminum alloy has the characteristics of high strength and light weight. Using an aluminum alloy tray as a chassis component can ensure the stability and durability of the chair while not adding excessive weight to the chair, facilitating its movement and handling.
• Rotating and Lifting Chassis: This type of chassis enables the chair to rotate and lift. The rotation function allows users to freely turn within the office area without moving the chair, facilitating communication with people in different directions or picking up items. The lifting function can adjust the height of the chair according to the user's height and usage habits, allowing the feet to be placed flat on the ground and maintaining a correct sitting posture.
• Butterfly Tray with Handle: The design of the butterfly tray is usually aesthetically pleasing, and the handle design increases operational convenience. Users can more easily adjust the angle and height of the chair through the handle to meet personalized usage needs. The prices of these components range from a dozen yuan to over a hundred yuan, and users can choose according to their own budget and needs.
