Modern Multipurpose Seating with Intuitive, Adjustment-Free Recline

The Humanscale Trea Chair is a modern multipurpose seating solution engineered for intuitive comfort, clean lines, and exceptional adaptability across today’s evolving workspaces.

Who Should NOT Choose the Trea Chair

Trea may not be ideal for users who need long-duration ergonomic task seating with full recline depth or advanced adjustability—those users may prefer the Humanscale Freedom or Liberty chairs.

Why Professionals Choose the Trea Chair

Professionals choose Trea for its elegant simplicity, effortless movement, and architectural design language that scales seamlessly across an entire workspace. The chair’s solid-state recline keeps users supported through natural shifts in posture, while its sculpted shell and optional seat pad deliver comfort that feels tailored without requiring adjustment.

As a unified seating family, Trea allows designers and organizations to maintain a consistent aesthetic from private offices to cafés, training rooms, lounges, and collaborative areas. Its durability, versatility, and award-winning design make it a trusted choice for commercial, hospitality, educational, and hybrid work environments.

Best for multipurpose settings, short-to-medium duration seating, and design-forward environments needing consistent styling across multiple spaces.
