A Fit for any Room

Created in collaboration with visionary designer Todd Bracher, Humanscale’s Trea is a multipurpose chair with a sophisticated design that embodies versatility.

Available with a variety of base, finish, and upholstery options, Trea can also be customized for use in a variety of spaces. Contact Hansen Interiors to order custom models.


Features

  • The innovative solid-state recline mechanism offers a 12° recline without requiring manual adjustments.
  • Trea’s contoured shells cradle the body’s natural curves for added lumbar support and mirror intuitive rotation from the hip.
  • A sleek waterfall seat edge reduces impact to the back of the knees and ensures an even distribution of pressure for ultimate comfort and relief.
  • The simple, restrained design allows the chair to integrate into interiors without overpowering a space.
  • Interchangeable bases and a choice of finishes enable Trea to be easily customized for different environments and uses but still maintain a uniform visual throughout

Innovation

Trea is engineered with a unique solid-state recline mechanism that offers the sitter 12 degrees of movement. The chair’s overall modular design makes upgrading and maintaining each component easy, minimizing the environmental impact.

Ergonomic Comfort

Trea’s waterfall-edge seat reduces impact to the back of the knees. A contoured backrest gently pivots to follow the natural point of hip rotation, cradling the body’s curves for lumbar support. The sitter can move freely and comfortably without adjusting any mechanisms or dials.

Beauty

Inspired by simple, natural forms, the Trea chair's sophisticated design embodies versatility. Functionally flawless and aesthetically pure, Trea offers the most comfort with the least effort, providing stylish support in any space.

Sustainability


Humanscale products are designed with a genuine focus on their environmental impact at every stage of their development. For Humanscale, the best designs in the world achieve more with less, and sustainability is the natural result of this focus. Made from highly durable parts, the Trea chair was built to last. Its unique solid-state recline mechanism does not use an erodible metal spring, ensuring the chair will perform as well on day one as it will in 10 years. Due to its robust construction will not need to be replaced frequently, thereby minimizing waste and offering a comfortable sitting experience for many years.

Humanscale treats sustainability as a core part of its identity, not simply a supporting message. The company approaches design with the idea that fewer parts, longer lasting materials, and simpler engineering can reduce waste while improving performance. This philosophy is reflected across its workplace products, which are developed to deliver long term value through durability, efficiency, and thoughtful material use.



Sustainability at Humanscale also extends into manufacturing and material selection. The company has worked to reduce waste, improve energy efficiency, and eliminate many chemicals of concern from its products and processes. Its focus on transparency and responsible sourcing helps support healthier interiors while giving designers and customers greater confidence in the environmental standards behind the brand.



In addition, Humanscale has invested in circular thinking through initiatives that support product longevity, refurbishment, and reduced environmental impact over time. By combining human centered design with measurable sustainability efforts, the company has built a reputation for creating workplace solutions that are intended to support both personal wellbeing and broader environmental responsibility.
