ERGONOMIC CERTIFIED
The Pro is engineered for people who sit for long hours. Whether you're working from home, gaming, or at the office — this chair adapts to your body, not the other way around. Backed by a 5-year warranty and passed a 120,000-cycle safety test.
World's First 3-Zone Floating Wing Lumbar Support
Most chairs offer basic lumbar support. The E3 Pro goes further with a 3-zone floating wing system — the central zone supports your spine and maintains its natural curvature, while the bilateral wings rotate 40° to cradle your waist from every angle. No more "empty waist" syndrome or chronic back pain from long sitting sessions.
Research shows 60–80% of people who sit more than 2 hours daily experience waist discomfort. The E3 Pro is designed specifically to fix that.
8D Precision Lumbar Adjustment
Fine-tune your lumbar support in 8 directions — up, down, forward, backward, and everything in between. Every body is different, and the E3 Pro adapts to yours precisely.
4D Biaxial Adjustable Headrest
- Headrest Frame Rotation: 70°
- Headrest Tilt and Rotation: 70°
- Up/Down Adjustment: 1.8"
- Forward/Backward: 2.2"
Cradles the head to disperse pressure and reduce neck fatigue. High-resilience materials ensure smooth, wobble-free adjustments with long-term shape retention. All adjustable with one hand.
6D Armrests — Fine-Tuned to Any Position
Height
Adjusts 3" up/down so elbows rest naturally — no more floating arms or shoulder strain.
Forward / Backward
Moves 1.2" to keep arms supported whether typing, reading, or reclining.
Left / Right
Shifts 1.2" to accommodate different shoulder widths for relaxed alignment.
Rotation & Tilt
Rotates 70° and tilts 6° — locks at any angle for gaming, drafting, or specialized tasks.
