Get to Know Gas Lifts

What is a Gas Lift?
A Gas Lift is a “hydraulic cylinder” located under the chair seat. Its main functions are:

• Adjusting the chair's “height”
• Supporting the “user's weight”
• Allowing for “smooth and fluid” movement when adjusting up and down

What is a Gas Lift Class 4?

Gas Lift Class 4 is a high standard for gas cylinders in chairs, with key features:

• Supports heavy loads (approximately 120–150 kg+)
• Strong structure, resistant to high pressure
• Durable, does not easily sink
• Meets international safety standards (BIFMA)

📌 Observation: The cylinder rod is thicker and more solid than general classes, and movement up and down is “stable and smooth.”

Why Choose a Gas Lift Class 4?

Reasons why “today's workers” should choose it:

✅ 1. Safer
Reduces the risk of cylinder rod breaking / sinking.

✅ 2. Stable Seating
No "wobbling or sinking on its own" sensation.

✅ 3. Supports Long Sitting Hours

Helps maintain a “consistent” sitting posture.
