It's hard enough to find a couch with a decent design these days at an affordable price, and when you throw green built into the whole equation, it becomes almost impossible. Well I think that the guys over at EcoFurniture.com have done a pretty decent job with their Savoy Collection of sofa's, loveseats, and armchairs. The sofa seems to be the best value to me, coming in just under $1000 for a custom built couch. Constructed of a solid wood frame that is kiln dried to prevent warping. Plywood used for shaping is always backed with solid wood. All wood used is from sustainably harvested sources. See their environmental policy here. Here is what they have to say about it:
The Savoy Collection uses a skilled combination of minimal lines and lush cushioning to give a modern, balanced look to your living room. These pieces feature generous, squared off, wide-set arms that offer a stylish symmetry. The smooth, semi-attached back pillows are as supportive as they are pleasing to the eye. Loose, boxed seat cushions provide a responsive comfort with clean lines that still add allure. A combination of double and single top stitching gives a well tailored charm, and extra-wide wooden legs provide compact style.
It is available with a number of different fabric choices in a sofa, loveseat, armchair, or ottoman.
