I recently purchased a used tree lounge (sat in it in the backyard...WOW, is this thing comfortable!!!), and am wondering about the safety harness. The only thing it was missing was the safety cable and chest harness. I am wondering if the safety cable system Tree Lounge sells is the only type that works with this climber...or if it is by far the easiest to use with this climber as opposed to a standard full-body harness?

Reason being, I am planning on buying a full-body harness to use with my hang-on's, and would like to avoid buying both if I could.

Thanks in advance.
