How to build a deck
(the spring construction under the cushions)
This will make a better deck than the original, you can use flw (page 10) cloth if you like (it won't stretch like burlap, page10) the #25 heavy felt pad (page 12) bridges over the springs, for a more uniform deck. Then with one layer of cotton added before you put your deck cloth (denim page 12) on you will have a very solid deck that will last for years.
