Trea

Designed by Todd Bracher

Timeless Design Has Never Been So Comfortable

A Chair As Dynamic As You

Healthier Daily Movement

Beauty and Performance

The Trea chair beautifully combines minimalist design with high performance to create a versatile seating solution for any space. Designed with a solid state recline mechanism, Trea provides intuitive comfort by automatically adjusting to the sitter's movements without the need for manual adjustments. The chair’s contoured shell cradles the body, offering ergonomic support, while its waterfall seat edge ensures even pressure distribution, enhancing long-term comfort.

Trea’s 12° supported recline feels as effortless as it is generous, powered by a Solid Stat Mechanism. No dials or knobs are required for instantly tailored support, adding comfortable movement to refined aesthetics.

A base for every scenario. Four star for static or dynamic task settings, cantilever for side seating, four leg for the home, and five star for high task. Take your pick, Trea has your bases covered.

Choose a Color, (Nearly) Any Color

Outfitting Trea with an upholstered seat pad adds a touch of color and customization to any space. Our textiles are carefully selected to enhance the ergonomic function and sustainability of our designs. Featuring a broad spectrum of colors, patterns, and textures, all are rigorously tested to ensure they perform as well after ten years as they do on day one.

The Design Story

Carefully considered.

Inspired by Nature, Designed by Todd Bracher.

Trea is a simple yet highly flexible light task chair, inspired by nature. Its minimalist surface behaves like a living shell, gently articulating against the body’s pivot points while moving in harmony with its user. As with all Bracher designs, Trea is function-first, and carries a clean, timeless aesthetic.
