This DIY outdoor sofa is made with common lumber that you can buy at your local home store. I used 2x6 pine and 1x6 spruce to make this. We used an outdoor finish to help protect the wood. The only special tools that I used is a Massca pocket hole jig. Other than that just a saw and a drill is all you need to build this amazing outdoor sofa. 350. 8 offers from £29.95.
