Admin October 17, 2026

The names of office chair parts include casters, chair legs, gas lift (height-adjustable rod), base, seat, armrests, backrest-seat connection (corner brace), backrest, lumbar pillow, headrest, wheels, five-star base, and neck pillow, etc..

Casters are components at the bottom of an office chair used for movement. They are typically installed beneath the chair legs, facilitating flexible movement of the chair on the ground. Depending on the material and design, they can be classified into various types to suit different floor environments and usage requirements.

Chair legs are the foundational structure that supports the entire weight of the office chair. A common design is the five-star shape, which provides more stable support and ensures the chair does not easily tip over during use.

The gas lift (height-adjustable rod) is a key component for adjusting the height of the office chair. Through internal pressure changes, it enables the chair to be raised or lowered, meeting the usage needs of users of different heights and making office work more comfortable.

The base connects the gas lift and the seat, playing a role in stabilization and support. It can bear the weight of the human body and evenly distribute the force to various components, ensuring the structural stability of the chair.

The seat is the part that directly bears the weight of the human body. Its design and material directly affect the comfort of use. A high-quality seat can provide good support and cushioning, reducing fatigue caused by prolonged sitting.

Armrests provide support for the user's arms, relieving pressure on the shoulders and neck. Their height and angle are usually adjustable to adapt to different usage scenarios and personal habits.

The backrest-seat connection (corner brace) is an important component that connects the backrest and the seat, ensuring a firm and reliable connection between the two. It can also adjust the angle of the backrest to a certain extent to meet different sitting posture needs.

The backrest provides support for the user's back, helping to maintain a correct sitting posture and reducing back pressure. Its shape and material design are crucial for comfort and health.

Lumbar pillows and headrests are additional support components. The lumbar pillow provides targeted support for the waist, relieving waist fatigue; the headrest can provide support for the head during rest, increasing comfort.

Wheels and the five-star base have similar functions to casters and chair legs, both aiming to enable the chair to move and provide stable support. Neck pillows have a similar function to lumbar pillows and headrests, providing additional comfortable support for users.
