Get comfortable looking good

The aesthetic is mid-century but the ergonomics are as modern as it gets. Designed to respond to your natural movements, Zeph provides complete support without needing adjustments. Just set the height with the push of a lever and let geometry do the rest. Zeph is engineered to ensure your body’s pivot points create the ideal counterbalance so that every recline is just right, leaving you feeling supported and energized throughout the day. 
Zeph is built simply, weighs just under 20 pounds, and has a capacity of 350 pounds. And it gives you more of everything that matters: comfort, colors, and style. The chair’s cushion is made from 50% post-consumer recycled content and 3D knit to exact dimensions so there’s no waste.
