If you're looking for a couch and you're not a bzillionaire, I don't envy your plight. Finding good, affordable vintage can be hit or miss (don't even look on Nashville Craigslist if you have a sensitive gag reflex), and opting for inexpensive furniture can be just as bad, as you end up with some busted loveseat you can't fix and are loathe to toss.
Based out of Eugene, Oregon, Ugo has a small line of simple, tasteful seatery that assembles easily, has some notable eco-attributes, and carries a non-insane price point. At TreeHugger we harbor a love/hate relationship with Ikea, and it's nice to add Ugo to the list of alternatives. All of Ugo's pieces are made in the US from laminated FSC pine, and you've got the option of recycled polypropylene, organic cotton, or recycled PET (soda bottle) filling for your cushions.
Ugo's chair, loveseat, and sofa all assemble without tools or hardware (it actually does look super simple), thus they go together fast; 31 seconds is the standing record. As for prices, the chair, loveseat, and sofa, filled with recycled poly (which is actually reclaimed from existing sources like mattresses, etc.) are $375, $489, and $549, respectively. Opting for organic cotton or recycled PET stuffing brings the tag up to $499, $679, and $799.
