Hey everyone. I had a couple questions about a dryad sleeping shelter.

How would you attach this to trees? Just run a piece of webbing through all three loops and then tie bowlines onto the carabiners and then how would you attach the carabiners to trees? That center loop doesn't seem structural so I don't know how important it is to have webbing go through it or not. The only loops with cord to hold up the cot are the end loops. You can see in photo two below that the center loop with carabiner is just dangling in the air.

Also, what the heck is this thing?!?!?!?!?! What is it used for?
