FAQ

Frequently Asked Questions

Q1: How are the armrests adjustable?
A1: Our 3D armrests adjust in three ways: Up/Down (~12cm range).  Forward/Backward (~5cm range). Pivot Left/Right (~34-degree angle). You can unlock all dimensions to find the perfect elbow support.

Q2: How does the recline function work? Will it tip over?
A2: There are typically two levers on the right side: one for height adjustment and another for recline control. The recline function allows you to lock at any angle or adjust the tilt tension with a knob to match your weight. It is designed to be safe and will not tip over suddenly.

Q3: Is the mesh durable? Will it sag over time?
A3: We use high-elasticity, high-strength Tesla mesh that undergoes rigorous durability testing. It is highly resistant to stretching and sagging, providing firm support for a long time.

Q4: What is the seat cushion made of? Will it flatten out?
A4: The seat is made of one-piece injected molded high-resilience foam, not low-quality recycled foam. This material is high-density and has excellent rebound, ensuring it maintains its shape and provides even pressure distribution for long-term comfort.

Q5: Is the gas lift safe?
A5: Safety is our top priority. The chair is equipped with a BIFMA/SGS certified Class-3 gas lift, which has passed rigorous explosion-proof tests. It is completely safe to use.

Q6: What is your warranty policy?
A6: We offer 5-year warranty on the frame, 3-year on the gas lift, and 2-year on components. During the warranty period, we will replace or repair any non-man-made defects free of charge.
