UFO may have an otherworldly name, but it is manufactured with the needs of the Earth—and little earthlings—in mind. German play equipment manufacturer Berliner Seilfabrik created the playground equipment to withstand the wear and tear that inevitably accompanies horseplay, to minimize the need for replacement parts in the future. Made from aluminum and steel that are 85% and 70% recycled, respectively, the modular UFO challenges users mentally and physically with ropes and nodes that are ideal for small climbers. berliner-playequipment.com
