Returning to Chicago for the second time, British furniture brand Isomi debuted the innovative Knit One chair by London-based designer Paul Crofts. Employing 3D knitting technology on a lightweight metal frame, the modular lounge replaces traditional foam with air, which is as zero-waste as you can get.

Arriving flat-packed, the voluminous seat is easy to assemble: Once the structure is bolted together, the knit sleeve slides right on. A modular system, Knit One by Isomi also includes a straight ottoman and an angled component.
