The replacement bungee cord kit is for replacing old or damaged cords on Bliss Hammocks Gravity Free Recliners. These will fit our standard or wide size zero gravity chairs. If purchasing for a standard size recliner (27" wide model) then just tie additional knotting at the ends since you will have a few extra inches of cording. The kit comes with enough cording to double up each section to create the double cording the chair originally came with. Detailed instructions are included.
