For San Francisco furniture company Council’s inaugural outdoor collection, Eric Pfeiffer of Oakland, Calif., design studio Pfeiffer Lab chose to go with a contemporary take on the Adirondack chair. A white, powdercoated steel frame supports the chair’s curved profile, which is made from weather-treated pine slats. Four wood finishes are offered, including natural (shown). Unlike its traditional counterpart, the Plank Lounger can come with or without arms and still pull off an air of elegance.
