There is an adjustment on the left side of the backrest strap, you can make more adjustments with it to help with comfort.
After getting settled in the web, you can take your shoulder straps of your shoulders and be a bit more comfortable. Always keep your weight against the tether and always put shoulder straps back on before coming down. (It will be uncomfortable when the web falls to your knees as you pull yoirself up on tether before coming down).
Warmer days, carry the web across one shoulder so the web will not get you as hot.
Sleeping, if you have the tall model, slide toward the tree placing your straddle against the tree, let the back rest and lumbar straps completely out letting the back lay almost straight away from the tree, lay down and sweet dreams.....
