The Double Brazilian Style Hammocks are tightly woven with 100% cotton cloth, allowing for a soft and airy, breathable fabric. You've never felt relaxation like this before. The polyester end strings are used to ensure a long-lasting hammock, as they're more durable than traditional cotton end strings. The double hammock can support two adults comfortably, with a 450lb total capacity. This hammock is easy to transport and is compatible with Vivere's 9ft Steel Hammock Stand, Vivere's Tree Straps, and Vivere's Ultra-Lite Tree Straps (sold separately).
