Duracord white poly rope hammock. Maximum density 8mm rope improves comfort by significantly reducing rope elongation under tension. This ensures a natural, more supportive fit. Each hammock is composed of over 1000-feet of densely woven cotton fibers. Individual ropes pull against each other to produce a lattice-like design, thus eliminating the need for knots within the rope bed itself. Features double-looped strands connecting the bed of the hammock to the hand-braided ring knots. Hardwood spreader bar features countersunk spreader bar holes that serve to reduce the severity of the friction between rope and wood. 13-foot long hammock from o-ring to o-ring with a hammock bed that is 6-feet 10 inches long and 55 inches wide. Built to accommodate up to two people at once allowing up to a 450-pound weight capacity. Two chains are included to provide 15 inches of hanging flexibility on either side of your hammock. The chains should be adjusted as the hammock naturally stretches to it's full length.
