This bench is designed to be built using just five 10′-long 2x4s. You can build it from sugar pine, paint it and spend less than $10. Redwood is also a great choice for outdoor projects like this (and that’s what the originals were made from) but it can then cost about $200. No matter what species you choose, select the straightest, most knot-free 2x4s you can find.
