Are You Experiencing Lower Back Pain?

Double-back chairs are designed to alleviate discomfort. An ergonomic chair relieves back pain, eases the discomfort of prolonged sitting, and maintains a productive working posture.

German Innovation. Dual-Back Technology.

Conceived by German physicist Dr. Brunig, the dual-back ergonomic concept is regarded as a historic "chair revolution." Biomorphic dual-back design ensures a consistent healthy posture, alleviating discomfort and pain.

The backrest moves with you! It’s like having two hands supporting your back at all times, guiding you to assume a correct posture.

Ergonomic Design, Care For The Spine

The chair body incorporates an ergonomic design, ensuring a more tailored fit to the human spine and alleviating pressure on the lower back.

Saddle-Shaped Seat Cushion

Prevents thigh compression and numbness during extended sitting periods by utilizing a saddle-shaped ergonomic design.
Conforms to various body types, providing a snug fit for the hips and legs, reducing leg pressure, and ensuring long-lasting comfort.

Backrest and Seat Cushion Thickened With High-Elastic Sponge Filling

Enjoy a comfortable and soft sensation.

Highly Elastic Woven Mesh Fabric. Aesthetics Meet Comfort.

Made from high-elastic woven fabric, this material provides a velvety touch akin to the feel of skin. Through a distinctive weaving technique, it achieves a harmonious blend of elasticity, softness, and durability.

Adjustable Backrest Height

Four adjustable height positions with a 1.57" range, each level offering a 0.39" adjustment, catering to individuals of different heights and body types.

Adjustable Headrest

The headrest is height-adjustable with a 0.39" range, and its angle can be adjusted up to 35°. It aids in maintaining the correct posture and reducing neck fatigue.

3D Armrests - Multi-directional Adjustment

3D multi-angle adjustment accommodates different heights, providing comfortable arm support.

90-135° Rocking Recline

With three locking positions at 90°, 110°, and 135°, the double backrest design ensures that pressure is evenly distributed on the back, protecting the spine from stress and enhancing your comfort while reclining.

Greatest office chair!

Comfortable, supportive, with so many adjustment options for different work circumstances. And the full lie back option is perfect for mini breaks, or listening to audio. I love it and it works beautifully with my Eureka desk.
