I just got my new Burrow, and it looks awesome. This is my first top quilt so forgive my ignorance. My question is about the two adjustable shock cord lengths that run from side to side, one at the thighs and one at the mid back. I assume these are to pull the sides under you, but they seem like more trouble than they may be worth in the hammock. Do other Burrow owners not use these or take them off? Thanks.
