Antimicrobial Lotus Textile

Engineered for the most demanding applications, this coated textile delivers exceptional durability, stain resistance, and water repellency. Its performance finish ensures effortless cleaning and long-lasting quality, making it an ideal choice for hospitality, healthcare, and other high-traffic environments where both resilience and refined aesthetics are essential.

Automatic Recline

Legendary designer Niels Diffrient’s focus on simplicity led to the patented gravity mechanism found in all Humanscale chairs. It uses physics and the sitter’s own bodyweight to provide optimized and automatic support without complex adjustments, so you can move effortlessly from position to position without operating manual knobs and levers.

Sustainable by Design

From removing Red List chemicals to building in Living Factories that are certified TRUE Zero Waste, our products are designed to benefit people and the planet.

Unmatched Durability

The durability of our chairs far exceeds industry standards. This means every part is stronger, less likely to fail, and will last for decades of heavy duty use.

Clean Gas Cylinder

Our cylinders are cleaner and more reliable than conventional cylinders. Unlike other chairs, our patented design seals grease in the lower unit to protect both user and chair.

Antimicrobial, Multi-Layer Arm Pads

Our antimicrobial Duron arm pads have a multi-layer design making them softer and five times tougher than standard arms.

Auto-adjusting Foot Rest for Stool Configurations

Designed to move in sync with the chair height.
