Why choose a "Level 4 Gas Stem" for an ergonomic chair?

A Level 4 gas stem is the "safety lift center" of the human body. Its core function is to safely adjust the chair's height and completely prevent the risk of explosion.

I. Core Function: Safe Lifting
1. Adjusting Seat Height: This is the most basic function of a gas stem. Using a lever underneath the chair, you control the air pressure inside the stem, allowing the chair to rise and fall smoothly, allowing you to easily find the perfect sitting position for your desk height, ensuring your feet are flat on the ground and your thighs are parallel to the ground, maintaining good blood circulation.
2. Cushioning ("Free and Easy" function): When you lean back, the nitrogen inside the stem provides a cushioning effect, making the reclining motion smoother and more stable, enhancing comfort.

II. Why is "Level 4" so important?
1. The stem is filled with high-pressure nitrogen. If the quality is substandard, there is a very low risk of explosion (although rare, it can be very dangerous). The "Level" is an international safety certification standard (ISO standard) established to address this risk. 2. This grade is usually clearly indicated on the gas rod tube (e.g., CLASS 4). The higher the grade, the stricter the safety standards.

A Class 4 gas rod is not only the core component that enables the chair's lift function but also the most critical barrier to user safety. It has undergone rigorous testing for high strength, high temperature, and durability, completely eliminating the risk of explosion.

Newly upgraded sixth-generation technology leads the way

Comprehensively upgraded chair for increased comfort and more user-friendly adjustments

Comparing Real and Fake Ergonomic Chairs

Liftable lumbar support for all heights vs. fixed lumbar support that doesn't provide precise support

6-D adjustable armrests with up/down/forward/backward/swivel adjustment vs. single-function design that doesn't meet your adjustment needs

3-D adjustable headrest with up/down/forward/backward/swivel adjustment vs. single-function design that doesn't provide a precise fit

165° reclining angle for comfortable work and rest vs. no reclining angle that causes back pain from prolonged sitting and prevents relaxation

Sacral lumbar support absorbs shock, reduces pressure, and supports the sacrum. True lumbar protection means no lumbar injury.

6D adjustable mechanical arms (front/back/up/down/rotation)

3D Adjustable Lumbar Support with Dynamic Lumbar Tracking and Sacral Support

6th Generation Support Technology:
Designed with bionic spinal mechanics in mind, this technology decomposes the lumbar region into three key areas: the upper lumbar support zone, the lumbar spine conforming zone, and the sacral support zone.
This prevents spinal compensation that "supports the lumbar spine but not the sacrum." Whether you're sitting upright, relaxing, or twisting your body, the elastic deformation of the floating wings provides "dynamic lumbar support," keeping the lumbar spine in a natural neutral position. This effectively alleviates the root causes of lower back pain and sacral compression caused by prolonged sitting.

Fitting and More Support:
Alpha a adaptive lumbar support provides front-facing support and back-support with elastic support.

Highly Resilient and Cushioned Backrest:
Double elastic support cushions backrest impact. This reduces the pressure on your lumbar spine and provides a more flexible and stable support.

Adaptive Lumbar Fit:
The elastic lumbar pillow offers a wider floating angle, adapting to the load point to provide additional support.

Mechanical switch for one-touch operation without bending over.

Seat depth can be adjusted 6cm by moving the handle upward.

Suitable for heights between 155cm and 185cm, with a maximum weight capacity of 200kg.

After numerous tests and model revisions, our goal is to ensure that the thighs and buttocks are fully involved in distributing body pressure, eliminating stress concentration.Tookfun
