Ergonomic Office Chairs Without Legrest Manufacturers

The tilt lock function in an ergonomic office chair without legrest refers to a mechanism that can fix the angle of the backrest tilt. Once the user adjusts the backrest to a comfortable angle, they can utilize the tilt lock function to secure the backrest in that specific position, preventing it from accidentally moving or changing angles during use.

Specifically, it relies on the following mechanisms:

Tilt mechanism: The chair's backrest contains a tilt mechanism that allows users to adjust the angle of the backrest by leaning back. This mechanism may include a series of gears, springs, and connecting rods that work together to provide smooth tilting action.

Locking lever: Users lock or unlock the backrest tilt by pushing the lever up or down. This lever is connected to the tilt mechanism, and when the lever is in the locked position, it mechanically prevents the tilt mechanism from further movement, thus fixing the angle of the backrest.

Resistance adjustment: Some advanced ergonomic office chairs without legrests also allow users to adjust the tilt resistance to customize the resistance and speed of the backrest tilt according to personal preferences and weight. This is typically achieved by adjusting the tension of the springs within the tilt mechanism.

When the user adjusts the backrest angle and locks it in place by pushing the lever, these components work together to ensure that the backrest remains in the selected position. The locking function is typically very reliable, providing stable support for users during prolonged use, and offering lasting comfort.

This feature is particularly important for users who need to maintain the same sitting posture for extended periods, as it ensures that the chair's support remains consistent with the user's back, reducing discomfort and fatigue caused by chair movement. Additionally, the tilt lock function helps improve user concentration and work efficiency, as users do not need to frequently adjust the chair, allowing them to focus more on their tasks at hand.


How does the back frame of a ergonomic office chair without legrest support the natural curve of the spine?

The backrest frame of an ergonomic office chair without legrest is specifically designed to conform to the natural curvature of the spine. Its unique curved shape can accurately match the curved parts of the spine, providing even support to the back and shoulders. This design not only helps alleviate the pressure from prolonged sitting but also effectively prevents or alleviates back discomfort.

The backrest frame is made of sturdy and somewhat flexible materials, ensuring it can provide sufficient support while accommodating different user body types and sitting postures. Moreover, some high-end models also feature adjustable functions, allowing users to customize the height and tilt angle of the backrest according to their height and body type for personalized support.

Lumbar support is another important feature of the backrest frame. With built-in lumbar cushions or lumbar indent designs, it provides additional support to the lower back, helping maintain proper posture and reducing the burden on the lumbar spine.

For office workers who spend long hours working every day, a chair that can support the spine can greatly alleviate work fatigue.
