With all the fancy desks that are heavy to lift and expensive to buy, why not just make your workspace out of cardboard? That seems to be what Flickr user Savio Ku did. Even the walls are papered with corrugated boxes.
As impractical as this may seem, cardboard furniture can actually be rather sturdy when structured the right way. For example, check out this DIY cardboard shelf. If you're looking to re-do your office space, don't forget that you can get creative with materials as well. It doesn't have to just be wood, plastic, or metal. What you're looking for might just be the box itself.
