At the beach, let the breeze do the work. String up a hammock, climb in, and just try to stay awake. We dare you:
Above: A Single Cotton Hammock is 179€ from Manufactum.
Above: Made of a tear-proof cotton weave, the hammock should be stored indoors during damp weather.
Above: A Wall Holder for Hammocks can be used indoors, as well, and will support up to 550 pounds of weight; it's 49€ from Manufactum.
