Need a nap this holiday season? Next to Madison Square Park is Flatiron Sky-Line, a spatial installation featuring tubular arches with white hammocks. The installation invites the public to immerse themselves "into the constructed tranquility of the Flatiron Plaza—skyline gazing, socializing, contemplating, and experiencing the surroundings." The installation, designed by architecture and design firm LOT, opened to the public in November, and will remain on view through the holidays as part of the Flatiron/23rd Street Partnership's “23 Days of Flatiron Cheer” programming. Get comfortable before it's too late!
