- Pick #2 Prime boards and sight down each one. Take the straightest and grab one spare of each size.
- Treated pine comes wet. Stack the boards flat with scrap spacers between them, out of the sun, for 2–3 weeks before you cut. Dry boards don't shrink or twist after you build.
- Use screws labeled for treated lumber (most coated exterior screws are) and galvanized brackets.
- Sand the faces and edges smooth, then stain once the wood is dry. A cedar-tone stain gives it the honey look in the photos.
- Wear a dust mask when cutting and sanding treated wood, and never burn the scraps.
Estimates based on typical Home Depot prices; your store may vary. Same cuts and same steps in either wood.

Good to know
How big is it?
24-1/2 inches square and 12 inches tall to the top of the frame, about 17 inches with the cushion.
Which cushion does it use?
One standard 24 × 24 deep-seat seat cushion, bought ready-made. It sits on top, flush on all four sides.
Which tools do I need?
A drill/driver, a miter saw or circular saw, a tape measure, a speed square, two clamps and a sanding block. Every joint is wood on wood with screws: no pocket holes, no glue-ups, no brackets.
Can I build it in pine to save money?
Yes. The plan comes with a second shopping list in pressure-treated pine, with the same cuts and the same steps. Pine needs a couple of weeks to dry and a coat of cedar-tone stain, but costs about a third as much as cedar.
