We don’t know why it’s so hard to find sidewalk sofas in the winter, but they’re a symbol of spring because that’s when they start to appear. The corner on which we found this one–Metropolitan and Kent Avenue in Williamsburg–seems to be a magnet for sidewalk couches. We’ve photographed a several of them there since last spring. Now that Northside Piers (in the background of the photo) has risen, it provides an especially nice juxtaposition between sidewalk living and luxury living, so keep them coming.
