Installed between two trees [can be up to around 10m apart]. We set up a 10mm steel cable with 2T webbing slings and zero-impact to the tree on a really long pendulum [perhaps 5-12m, depending upon trees] to give a awesome Nest Swing. With a diameter of up to 1.45m this is a luxurious space for group play and grown-up relaxation with outdoor cushions.
