H5 - Ergonomic Office Chair

Reduce Carbon Footprint , Protect Our Plane

This is a conversation with nature. As environmental challenges intensify, oceans risk becoming the final resting place for plastic waste. The Sunon H5 ergonomic task chair responds with innovation — crafted from ocean-friendly recycled plastic to create a truly sustainable, modern office chair. Designed as an adjustable, comfortable office chair, H5 maximizes material efficiency while supporting a low-carbon future and healthier office seating environments.

You Will Forget You Are Sitting in a Chair

The integrated chair structure externalizes the contours of the spinal column, and is designed in a structured way based on the golden curves of the neck, shoulders, waist, hips, and legs, providing a differentiated sensory experience of "fitting, supporting, and pulling" for the entire spinal column. This allows the muscles of the body to be fully relieved of pressure, and from the moment of sitting down, one can feel as if gravity has been forgotten.

Move With You

From manual adjustments to dynamic adaptation, the Sunon H5 ergonomic task chair delivers an interactive seating experience where the chair moves as one with your body. Featuring a self-weight tilting mechanism, the backrest tilts up to 16° and the seat rises up to 8°, naturally following your posture changes. As an adjustable, modern office chair, H5 becomes a seamless part of your sitting posture, closely fitting and stably supporting you throughout the workday — making it a truly comfortable office chair for every workspace.

For Easy Storage

The H5 ergonomic task chair features a foldable backrest, making it compact, portable, and perfect for outdoor travel. This adjustable, modern office chair by Sunon reduces packaging volume, increases container capacity by 1.4x, and helps lower carbon emissions — delivering a sustainable, comfortable office seating solution without compromising ergonomic support.

One Chair One Colour One Space

From headrest to base, the Sunon H5 ergonomic task chair embraces a minimalist, single-color design, creating a visually harmonious and unified spatial solution. This modern, adjustable office chair seamlessly blends into any workspace, offering a comfortable seating experience without sacrificing style.
