A gas lift consists of multiple smart components that together provide comfort, stability, and durability in your chair. The gas-filled cylinder provides the force for height adjustment, while the piston ensures smooth and controlled movement. The internal lock keeps your chair firmly at the correct height so you don't slowly sink down. The switching pin activates the adjustment, and the piston protective layer protects against wear for a longer lifespan. The decompression interval ensures that pressure is released in a controlled manner for safe and comfortable use. Together, these components ensure your chair remains reliable, every single day.
