‌
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.

Don't see the answer to your question?

Which version of the ErgoChair Ultra is better? TPE or mesh?
There is no right or wrong answer. It depends entirely on personal taste and work style. For the minimalist, we offer a zero mesh, ‘bare-bones’ TPE edition. And for the more colorful, we offer our breathable mesh versions in blue, black, and gray.

Is ErgoChair Ultra suitable for taller people?
The height of the ErgoChair Ultra can extend up to 44 inches and supports up to 300 lbs, but keep in mind the body shape of the user also needs to be factored. Read this article to help determine the most suitable chair for you.
Does the ErgoChair Ultra come assembled?
No. ErgoChair Ultra ships and delivers un-assembled. Assembly is easy and straightforward, takes just a few simple steps, and all tools required are included in every package.
What is TPE plastic?
Thermoplastic elastomer (TPE) is a blend of polymers (usually a plastic and a rubber) that consist of materials with both thermoplastic and elastomeric properties. While most elastomers are thermosets, thermoplastics are in contrast relatively easy to use in manufacturing, for example, injection molding. Thermoplastic elastomers show advantages typical from combining rubbery materials with plastic materials.
What are the benefits of a frameless chair?
A frameless chair doesn't box you in. Designed for lean, fast moving workplaces - this is not a chair you slump into. It encourages movement, and keeps you agile and engaged, even while sitting.
What does the warranty cover?
The warranty covers all manufacturing defects that may occur within 2 years from date of delivery. Warranties do not cover normal wear and tear or misuse of product.

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.
