The Mathias Chair honors classic mid-century style while reimagining it for today’s workspace. Premium materials and ergonomic support create a seat that is as iconic as it is comfortable.

Features

  • Honoring the Classic: Eleven-layer hot-pressed walnut plywood shell, a modern tribute to the iconic Eames silhouette.
  • FSC® Certified Wood: We use FSC® certified wood, which ensures that our pieces are made sustainably, and the world's forest resources are used responsibly.
  • Premium Napa Leather: Crafted from top-grain head-layer hides, all primary touchpoints are upholstered in genuine Napa leather. Non-contact areas, such as the underside of the armrests or hidden surfaces, are made with high-quality PVC for enhanced durability.
  • Sculpted Support That Moves With You: Thickened foam padding follows the natural curve of your back, offering ergonomic support and pressure relief throughout the workday.
  • Sleek Alloy Foundation: The aluminum base offers both visual lightness and structural strength, blending durability with design finesse.

Has Completely Transformed My Workday

As a researcher, I decided to take a chance on this chair during its month-long pre-order. The wait felt long, but my goodness, it has been revolutionary for my well-being. It’s not about flashy gimmicks; it's about flawlessly executed ergonomics. The ability to push a simple lever and have the backrest change its curve is a feature I didn't know I needed but can't live without now. It feels like every component was engineered with a deep understanding of the human body. This chair was a profound investment, and the wait was a small price to pay for this level of daily comfort.

Might Have to Buy a Second One

I bought this for my home office, but now I have to fight my wife for it. She says it's the only chair that doesn't make her hips sore. I guess that's the highest praise you can give!

Looks Absolutely Stunning in My Office

I was looking for an office chair that didn't look like a typical office chair, and this one is a work of art. My decision was based almost entirely on its aesthetics, and it did not disappoint. The craftsmanship is obvious, especially the beautiful walnut grain on the back—it has a warm, premium feel that elevates the entire room.If you're looking for a chair that makes a strong design statement, this is absolutely the one.

Finally, My Back Pain is Gone!

This chair changed everything for my 10-hour workdays. The S-shaped supports and the adjustable back curve provide perfect, customized support. Based on this experience, I would absolutely recommend any product from Eureka.

You Get What You Pay For

This chair is not only beautiful, but it's a huge upgrade. Compared to the $200-$300 chairs I've had before, the comfort and build quality are on a completely different level. The design is so distinctive, especially the view from the back—it proves that a good chair is truly a worthwhile investment.

The Difference Is in the Details

Worth Every Penny but the Wait

I waited a month for the pre-sale, but it was worth every bit of the wait. The build quality and comfort are on a whole other level.
