Product details
Industry-Leading 6D Ergo-Motion
Take control of your comfort with our revolutionary 6D armrests. They don't just go up and down—they rotate, slide, and even tilt with the backrest. Whether you're gaming with a controller or typing at a desk, the M1 armrests provide continuous support for your elbows and shoulders in every posture.
Dynamic Spine & Pelvis Support
The Sylph features a 2-way adaptive lumbar support that adjusts to your spine's natural curve. Combined with the adjustable seat depth, it ensures a perfect fit for users of all heights, effectively distributing pressure across your thighs and lower back to eliminate numbness during long sessions.
First-Class Relaxation Mode
Transition from deep focus to pure relaxation in seconds. The Sylph supports a wide 135° tilt with multiple locking positions. Paired with the integrated retractable footrest, it transforms your workspace into a personal nap pod, allowing you to recharge with zero gravity comfort.
Military-Grade Safety & Airflow
Built on a foundation of trust. Featuring a SGS-certified Class-4 gas lift and a high-strength steel base, the Sylph is built to last. The entire chair is wrapped in high-elastic breathable mesh, ensuring optimal airflow to keep you cool and concentrated even in high-pressure environments.

FAQs
Please read our FAQs page to find out more.
How do I adjust the 6D armrests for the best support?
The Sylph's 6D armrests offer height, width, depth, and angle adjustments. A unique feature is the Linkage Tilt: when you recline, the armrests maintain their angle relative to your body, keeping your arms supported even in a resting position.
Is the seat depth adjustable? Why is it important?
Yes, the Sylph allows you to slide the seat cushion forward or backward. This is crucial for ergonomics—it ensures that users with longer or shorter legs can maintain proper circulation in their thighs while keeping their back firmly against the lumbar support.
What is the maximum weight capacity for the Sylph?
hanks to the reinforced steel base and the SGS Class-4 heavy-duty gas lift, the Sylph is designed to safely support up to 200kg with rock-solid stability.
Can the headrest be customized?
Absolutely. The 3D Headrest can be adjusted for height and angle, and it also features a rotational pivot. It is specifically designed to cradle the cervical spine, preventing neck fatigue whether you are looking up at multiple monitors or reclining for a break.
Is the mesh durable? Will it sag over time?
We use a proprietary High-Elastic Polymer Mesh that has undergone rigorous tension testing. Unlike traditional foam or low-grade mesh, our material retains its shape and supportive tension for years, while providing superior breathability compared to leather or fabric.
Is assembly difficult?
Not at all. The Sylph comes with a detailed manual and all necessary tools. Most customers complete the assembly in 15-20 minutes. The major components like the backrest and seat mechanism are pre-assembled to ensure precision and safety.
