Green furniture fans can give you three reasons to use cardboard as a building material:

• It’s cheap.
• It saves trees compared to traditional wood.
• It’s lightweight, so you can move it around more easily.

As a result, cardboard furniture has gained popularity around the world as a green alternative to traditional furniture.

The Terramia blog showcases a wide range of cardboard projects, from lamps to chairs to benches. And if you feel like making your own cardboard chair, artist Andrew Senior has posted an FAQ that provides step-by-step instructions. It probably won’t look as nice as a chair made by a professional designer, but it should prove an interesting challenge for amateur furniture makers looking to go green.

For eco-aware pet owners, Everyday Studio sells pet furniture made from cardboard. From cat scratching posts to napping spots, people looking to pamper their pets have some stylish options that contain lower tree content.

Cardboard furniture may raise some durability concerns compared to thicker, traditional furniture, but the innovative designs and materials may give it just enough legs to make it into the mainstream.
