Nucleus is a new ergonomic task chair offering from the HON Co. The seat is crafted out of suspension material stretched over a contoured frame and topped with foam, and the back is clad in ilira-strech M4—a four-way–stretch mesh—and is available in three neutral tones. Lumbar support requires no manual adjustment. The task chair is available with or without arms, as is a coordinating guest chair (which stacks four high and can be outfitted with either casters or glides). Designed by Marcus Koepke, Nucleus is SCS-certified as Indoor Advantage Gold, and the seat can be upholstered in any of the company’s fabric options.
