Humanscale Stackable Cinto Armchair

About the Design

Developed in the Humanscale Design Studio by a global team of designers and engineers, Cinto puts comfort first. As well as offering unrivaled support in a streamlined aesthetic, its lightweight recycled construction makes carrying and storing the stackable chair effortless. Thanks to an innovative ergonomic design and floating backrest technology, Cinto supports the sitter’s lower back, offering automatic lumbar support unlike any other stackable office chair.

What is a Net Positive Product?

Cinto is Living Product Certified, meeting the most rigorous sustainable manufacturing criteria. This means that Cinto is climate, water, and energy positive. Every time we make these products, the planet is better off. With a mission to create a healthier world, we are proud that over 60% of our products are certified net positive.

Stacking Convenience

Style, Comfort, and Utility

Cinto features an innovative backrest that reclines and automatically adjusts lumbar support, plus a seat pan design that uniquely distributes the sitter’s weight to reduce pressure points. Available in an array of colors, Cinto complements any residential or commercial interior.

Made from lightweight recyclable materials, Cinto’s design also helps to reduce shipping weight and create a smaller carbon footprint. Proven to be environmentally sound, Cinto is certified by GREENGUARD and level® and contributes to valuable LEED credits.

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.
