Promotes Spontaneous Movement
Niels Diffrient’s revolutionary approach to chair design fundamentally changed the relationship between the user and their seating, replacing cumbersome controls like locks, knobs, and levers with an intuitive system using principles of physics and the sitter’s own body weight. His work embodies a philosophy of simplicity, where the chair adapts automatically to the user, providing instant support across any position without requiring manual adjustments. This ethos makes World LM’s functionality “invisible to the user,” ensuring that anyone can sit comfortably without instructions. It also encourages healthy, spontaneous movement while lending the sitter ergonomic support throughout every posture.

Patented Form Sensing Mesh™
World LM’s tri-panel, low stretch mesh back ensures a personalized fi t for every user, conforming to the body’s natural contours to deliver tailored lumbar support and maximum adaptability. Unlike traditional single-panel mesh chairs, Form Sensing Mesh takes on the exact shape of the sitter’s back, as if it were made just for them. Perfect for dynamic workspaces, World LM promotes balanced movement and unmatched comfort throughout the day.

True Minimalism and Great Ergonomics Coexist Beautifully
Built with just 78 durable components, World LM is a testament to the power of simplicity. With its lightweight construction and advanced materials, the chair proves that great design can be both beautifully minimal and supremely functional, setting a new standard for ergonomic excellence.

Express Yourself
World LM redefines versatility with a curated selection of stunning textiles. Choose from an extensive range of Autumn and Corde 4 fabrics to elevate the chair’s aesthetic and seamlessly integrate it into any space—whether it’s a professional office or a stylish home setup. With its perfect balance of comfort and customization, World LM looks as good as it feels.
