Manual Function Office Chair

There are various types of office chairs with manual functions. Below are introductions to two common manual function office chairs and their features:

MARKUS Office Chair:

• Manual Tilt Tension Adjustment: This ergonomic office chair features a manual tilt tension adjustment function. Users can turn the knob on the right-hand lever beneath the seat to increase or decrease the resistance when leaning back in the chair. This design allows users to adjust to the most comfortable tilting position based on their body weight and sitting habits, providing good support for both long working hours and short breaks.
• Adjustable Seat Height: Another key feature of this chair is its manually adjustable seat height. Users can adjust the seat to the appropriate position according to their height and the height of their desk, ensuring that their back and legs maintain a 90° angle, which helps maintain correct sitting posture and reduces physical fatigue and discomfort.
• Synchronized Tilt Mechanism: The MARKUS office chair is also equipped with a synchronized tilt mechanism, enabling the chair to move in sync with the user. When the user leans back, the backrest moves more than the seat, facilitating the expansion of the torso and hips, further enhancing sitting comfort.

SumLush Fit CC Ergonomic Chair:

• BackFit Four-Way Back and Lumbar Support System: This chair adopts the BackFit four-way back and lumbar support system, supporting manual adjustment in four directions: up, down, forward, and backward. Users can adjust the support position according to their lumbar curve, ensuring the chair fits closely against the back and waist, providing a personalized support experience. This design helps relieve lower back pressure caused by prolonged sitting and prevents lumbar spine diseases.
• Flexibility of Manual Adjustment: In addition to the four-way back and lumbar support system, other functions of the SumLush Fit CC ergonomic chair may also support manual adjustment (refer to the product details for specifics), such as armrest height and angle. Users can make flexible adjustments according to their needs to meet different usage scenarios.
