The battle over who can out-green whom has moved into the arena of furniture. A saleswoman at Crate and Barrel tried to sell my husband and I on a tomato-red couch (seen above in a leather version) over the weekend by telling us that it was ?green.? Promotional materials boast of its ?sustainable? hardwood frame (whatever that means) and its ?soy-or plant-based? cushions (made of exactly what if not soy? roses? thistles?). Well, that?s great. But how ?sustainable? is the couch in terms of living up to family life? Our saleswoman knew a lot less about that.
