March 10, 2008 - The latest entry in the green office furniture trend: modular blocks of super-sturdy cardboard that can build chairs, desks, even walls in minutes. Chicago-based startup Bloxes is hoping its new invention will be coming to a workspace near you (maybe even yours).

The 100% recyclable corrugated cardboard forms are lightweight but strong (see photo). They can also be collapsed flat, saving on shipping costs.

"Bloxes can connect with each other on all six sides, so you can use them to build walls, benches, tables, tunnels," says the company website. "And because the varied surface and complex internal structure helps dampen sound, they're great for managing acoustics in offices, studios and other places."

A $60 pack of 20 bloxes can build a 3x4-foot wall. For more information, click here.
