I’ve been neglecting the site for quite some time. So — here’s a post on the backyard sofa set we built this past summer (now that we’ve had our first snow it feels like a perfect time to think back to the good parts of summer despite covid).
The design is pretty straightforward — 2×4 cedar + screws + cushions and a few pocket holes for some sections that would have otherwise required really long screws.

The design is based off these Ryobi plans https://www.ryobitools.com/nation/projects/2651
We modified the plans slightly by adding additional 2x4s for back support and a notched top-piece. The overall length we modified based on the cushions we picked out. Here’s a link to the cushions we went for:
