The Nirvana Hammocks feature a durable fabric made from all-weather and solution-dyed olefin, which is resistant to rot, mould, and mildew. The polyester rope is a solution-dyed synthetic blend that balances the softness of cotton with the durability of polyester. The spring bar is made from hardwood, which is 5 times denser than pine, cedar, and redwood, and ages naturally to a beautiful silver grey. The hanging hardware is zinc-plated for rust protection and longer outdoor life. Dimensions - Single size: 78 inches x 48 inches Overall length: 132 inches Weight Capacity: 250 pounds
