2. Seat Depth Adjustment

Proper seat depth adjustment allows you to be seated with your back and thighs well supported.

The seat can be moved forward or backward as per your requirement. Your back should be properly aligned to the back of the chair.

Seat Depth, when properly adjusted, allows users to retain adequate backrest while equally spreading their weight across the seat cushion.

Pressure at the ischial tuberosities and the knee joints will be relieved when weight is spread properly.

2. Water Fall Seat Design

Synchro-Tilt office chairs have Water Fall Seat Design that helps you avoid stress on the thigh while tilting your back.

It allows for better circulation and less stress on the lumbar regions.

3. Seatback Tension and Tilt Control

This feature allows you to control the seat and back tilt using a knob or a lever. This Mechanism works in cooperation with your weight.

As a result, a heavier user will need more tension, while a lighter individual will need more control.

You may feel uncomfortable tilting backward if the tension is set incorrectly for your weight or height.

It’s also possible that you’ll have the reverse problem and be unable to recline at all.

Seatback tension and tilt control allow you to set the tension accurately so that you can recline comfortably.

4. Back Height Adjustment

In general, the lower portion of the spine should have an inward curve (lordosis).

When seated, this curvature is reduced, putting additional strain on the lower vertebrae.

When sitting, a correctly positioned lumbar support applies external pressure to the lower back, allowing the spine to maintain part of its natural curvature while reducing stress on the vertebrae.

The back height adjustment feature allows proper adjustment so that your spine is well supported.

How does Synchro-Tilt Mechanism Work?

First, the ’tilt’ function enables you to lean back or forward as the chair follows, and the ‘tension’ feature enables you to alter the tilt force.

The tension is adjusted to fit your weight and desired seating posture by the Mechanism.

The point is what is referred to as your “tipping point.” This is the “point” at which the chair’s push force equals your body weight!

As a result, you should not be pushed forward and feel as though the chair supports you when you sit.

There should be enough tension so that you may recline by pushing back a bit with your feet, and the chair will follow you when you sit forward.

On the other hand, you shouldn’t be able to fall on your chair, and it shouldn’t be so stiff that you can’t recline at all.

Synchro Mechanism Chairs include a tilt mechanism that automatically adjusts the seat back and the seat together for optimal support.

Some Synchro Mechanism Chairs feature a lever to secure or release the synchro motion, as well as a synchro tension adjustment to fit your weight.

Other synchro systems are solely weight-activated, meaning they alter the synchro tension based on your weight.
