It’s like swinging, surfing and sailing through the air, on a sturdy hard rock maple base. Adjustable handles slide up and down on the high-strength, braided rope, so swurfers weighing up to 250 lbs. can stand or sit with confidence. With 80 ft. of UV- and mildew-resistant rope, it can swing from a 20 ft. branch. Wow! Adult supervision suggested. From The Rob Company, for ages 6 yrs-adult.
