What does cardboard furniture have to do with technology?

As prices rise for oil and raw materials (even sawdust), fans of furniture made from cardboard call it more earth-friendly and affordable than its wooden counterparts, which usually requires felling trees, or furniture made of pressboard, which contains toxic glues. It's also lightweight and can be packed flat for easy shipping.

Star architect Frank Gehry is known as the design pioneer in this realm. Between 1969 and 1973, his "Easy Edges" series of designs layered corrugated cardboard to create chairs and tables capped by a wooden layer for extra strength. Design schools regularly teach Gehry's forms.

Cardboard as a building block is slowly gaining in appeal around the world. The 2000 Olympics in Sydney featured cardboard furniture. In Hong Kong, cardboard is used for coffins.
