Humanscale World LM is a streamlined ergonomic task chair with a tri-panel Catena mesh back, weight-sensitive recline, pivoting backrest, adjustable arms, and soft casters. Choose Black or Gray frame and four seat color/material options.

World LM is Humanscale doing what Humanscale does best: making ergonomics feel effortless (and look ridiculously clean while doing it).

This is the streamlined edition of the original World Chair—built with fewer parts, priced with purpose, and still delivering the good stuff: a tri-panel mesh back that shapes to you and a weight-sensitive recline that moves when you move. No “chair cockpit.” No instruction manual energy. Just sit down and let physics handle the rest.

KCOD’s take: this is the premium, design-forward task chair for teams who want serious comfort—without paying for features they’ll never touch.

  • Pivoting backrest that moves with you to support lumbar across postures
  • Tri-panel Form Sensing Mesh back designed to conform for personalized support
  • Adjustable arms (standard on all KCOD-configured chairs)
  • Simple, durable build designed with fewer components for long-term reliability
