1:2 Chair

1:2 Chair is an innovative, adjustable furniture design that exemplifies sustainable thinking and adaptable functionality in contemporary furniture design. Created by designer Yahe Zhang, this versatile seating solution addresses the evolving needs of families while promoting environmental consciousness through its ingenious construction. The chair's distinguishing feature lies in its adaptable height adjustment system, which allows it to serve both children and adults through different life stages, effectively reducing wood consumption and material waste. Crafted from high-quality beech wood and complemented by cotton linen cushioning, the chair showcases exceptional craftsmanship through its heat-formed backrest and CNC-milled components. The design incorporates a sophisticated dismountable structure utilizing embedded nuts and precise mortise and tenon joinery, ensuring both stability and ease of assembly. With dimensions of 750mm in height, 540mm in width, and 480mm in depth, featuring a seat height of 445mm, the chair employs a flat-pack design that optimizes shipping efficiency and reduces environmental impact. The surface treatment options include wood wax oil or open paint finishes, preserving the natural wood grain aesthetics. This thoughtful design, which earned the Silver A' Design Award in the Furniture Design category, represents a significant advancement in sustainable furniture design, combining practical functionality with environmental stewardship while fostering parent-child interaction through its assembly process.
