Bokträ
A Foldable High Chair
Materials: Beech wood, steel, and cotton canvas
Team HAS Sustainability Project
Team Member: Zhiyu, Zak, and Cathy
Our study includes Manufacturing, assembly, packaging, use and end of life.
Design brief
We set to redesign IKEAS ANTILOP high chair to be more sustainable
Reduce environmental impact
Design for storage when not in use
Solve the pain points from existing product
Challenge
Fast fashion furniture
Fast furniture, which is mass-produced and relatively inexpensive, is easy to obtain and then abandon.
2030
IKEA Sustainability Strategy
"By 2030, our ambition is to become climate positive and regenerate resources while growing the IKEA business"
Introduce
ANTILOP high chair is easy to take apart and bring along so your child sits safely whether you are at home, at your friend’s place or at a restaurant. Enjoy your meal!
