Functions of Computer Office Chairs

Computer office chairs have a variety of functions, mainly divided into three categories: basic adjustment, body support, and convenient additional functions.

Basic Adjustment Functions:

1. Seat Height Adjustment: The seat surface can be raised or lowered through a gas rod structure to accommodate people of different heights and desk heights. After adjustment, ensure that both feet are placed flat on the ground naturally, with the thighs horizontal, to avoid leg suspension or pressure and maintain a proper sitting posture.
2. Backrest Angle Adjustment: The normal adjustment range is from 90° to 135°. When working, it can be kept upright to fit the lower back; during lunch breaks, it can be reclined for lying down, allowing flexible switching between work and rest modes and relieving back muscle tension.
3. Seat Depth Adjustment: Mid-to-high-end models support slight forward and backward adjustment of the seat surface to accommodate people with different leg lengths. After adjustment, it can ensure even pressure on the buttocks and legs, avoiding waist suspension or pressure on the back of the knees.

Body Support Functions:

1. Lumbar Support: The core configuration is an adjustable lumbar pillow that supports slight up-and-down and forward-and-backward adjustments to precisely fit the natural curve of the lumbar spine and fill the gap between the lower back and the backrest. For example, the backrest of the Sihoo C300 Second Generation Lite can be adjusted up and down independently, and its sliding and gliding back-following function provides better lumbar support when reclining.
2. Head Support: High-back computer chairs are equipped with adjustable headrests to accommodate the neck heights of users of different heights, supporting the back of the head and neck and relieving neck stiffness and soreness caused by long-term looking down at the screen.
3. Armrest Support: Adjustable armrests can accommodate various postures such as typing, leaning over the desk, and resting, effectively supporting the arms, distributing shoulder pressure, and preventing shoulder and neck pain, hunched shoulders, and other poor postures.

Convenient Additional Functions:

1. 360° Free Rotation: The chair body can rotate flexibly, making it convenient to pick up items or operate sideways without moving the entire chair, especially suitable for small office spaces.
2. Silent Wheel Movement: The bottom is equipped with silent universal wheels that provide smooth pushing and pulling without damaging the floor. It allows easy adjustment of sitting posture or chair position, reducing the trouble of frequent getting up.
3. Breathable Material Design: Mainstream designs use high-elastic mesh or breathable sponge materials with good ventilation, preventing sweating and stickiness during long sitting and effectively improving discomfort caused by summer humidity.
