World LM Task Chair

Designed by Niels Diffrient, the Humanscale World LM is a minimalist task chair that draws inspiration from clothing design — the tri-paneled Form Sensing Mesh back adapts precisely to the shape of each sitter's spine without any manual adjustment. The weight-sensitive recline mechanism reads your body weight to provide calibrated resistance, accommodating users from 5'0" to 6'4" and 100 to 400 lbs. With fewer parts than a conventional task chair, the World LM is built for long-term durability and easy maintenance.

GREENGUARD Gold certified for indoor air quality and Level 2 certified for environmental impact, the World LM pairs genuine ergonomic performance with a minimal material footprint. The chair measures 25.75"W with a seat height range of 15.6–21 inches and weighs just 28 lbs. Backed by Humanscale's 12-year warranty on parts and 5-year warranty on textiles. Available in Black and Silver frames with Aurora textile seat in Black, Ocean, and Mist, or as an all-mesh configuration. Available at Comosum.
