The Tri-Leg is perfect to bring along when space is limited and weight is a factor. The Tri-Leg folds up and fits compactly into a carry bag. The 2 pound stool is made of a powder coated steel frame and has a reinforcing extra center support system to hold up to 250 pounds. The fabric is made of a durable 600D Polyester. There is also a carry strap attached to the Tri-Leg in case you don't want to bring the carry bag along.
