The World's First Matrix Structure Chair | Autonomous ErgoChair Ultra

ErgoChair Ultra Overview Specs FAQs Reviews

Inspired by endurance cyclists, we envisioned a long-haul chair. That obsession led to Ultra technology, featuring a revolutionary matrix structure with a unique 62-spring matrix that provides superior sit-bone support. Ultra lets you sit for 12 hours, with 87% of users reporting pain relief. Now you can invent cool stuff all day without a hitch!

Optimal Pressure Distribution

Matrix Structure Padding.

Our matrix structure, with 62 nodes and 186 struts, is tuned in a way impossible with foam. It supports your sit bones over a larger area, creating a hammock effect and ensuring even pressure —not straining surrounding tissues.

‌

Fully Adjustable

Adaptive Backrest.

Innovative ribs keep the backrest flexible and tensioned, eliminating hard edges. Enjoy seamless posture changes with a backrest that flexes and twists with you.

Back Fit

Invisible Lumbar Protection.

Wider and directly tensioned by an X shape at the lumbar region maintain good posture, while thinner and more elastic near the shoulders give unrestricted movement.

Back Frame Design

Posture Alignment.

Inspired by the human spine with flexible ribs. The design aligns the backrest with your spine’s curve, providing constant support whether leaning forward or reclining.

Ventilation

Air Mesh.

Stitched directly onto the webbing, air mesh enhances edge flexibility and breathability, keeping you cool and comfortable. No more sweaty back!

Earth friendly, Enduring strength, Firm, yet pliant.

Design Story

The design process for the Autonomous ErgoChair Ultra has been highly meticulous. To start, we coordinated extensive research across our teams in search of inspiration. Once the framework was set on natural structures, countless hand-drawn designs were prepared combining various natural forms to create something wholly unique. Once we reached a consensus on an overall direction for the design, our 3D Design team began modeling the proposed design in a virtual space. From this medium, the team was able to create a realistic representation of surface dimensions and better understand the potential of Autonomous premium ergonomic office chair. This work became the basis for the prototype. Through extensive testing and experimentation, elements were added and removed from the design during the prototype stage until the chair’s capacity could be fully realized. No expense was spared, and no stone left unturned. This process allowed the ideas behind the conical springs, natural spine design and unique use of TPE (thermoplastic elastomer) to be brought to life.
