I’m so excited to be sharing the build steps and printable plans for this DIY Outdoor Sofa from 2×4 Pine and Cedar lumber with you all! I built this a few months ago, but haven’t had time to put the plans together until now. I absolutely love this bench. It’s comfortable and eye-catching. Whenever someone sees it they always comment on it and want to touch it.

I can always tell that someone really likes one of my builds when they have to touch it and look at me in disbelief when I say I built it. LOL. Now, just in time for Spring, I can tell you how to build your own eye-catching bench that people won’t stop touching. πŸ˜‰

DIY Wooden Bench Design Notes

Let’s talk bench cushions!

I bought my cushions at β€˜At Home’. They sell them in a dozen colors and styles. Amazon also has some that are similar (like these). My cushions are 25” wide, 24” long, and 6” deep. I designed this bench for those cushions. If you want to use cushions with your bench, I recommend buying them before you build. Then line them up, tightly in a row, and measure the width.

My bench seat is 72” wide. The cushions are actually about 73” when pushed together. Building the frame a little tighter holds my cushions in tight and keeps the seat firm. You may need to adjust the dimensions for this bench, if you’re cushions aren’t a very similar size.

Now, let’s talk money!

I don’t always breakdown costs on my free plans. But, I thought it might be helpful on this DIY Outdoor Sofa from 2×4 build. The 10 Pine 2×4 framing studs cost less than $30 in my part of the US. I used indoor, kiln dried pine because I knew I was finishing the wood and because my bench is protected from the rain and sun on my porch.

If your bench will sit in the rain, sun, or snow, you might want to use Pressure Treated 2×4’s. Just remember, you may need to let them dry out before building with them AND your Pine will have that yellow PT tint. So, pick your stain or paint finish based on that. I’ve had great results staining PT Pine with Minwax’s Jacobean Wood Stain (on my L-Shaped Backyard Bench). Be sure to use wood conditioner before staining pine. Spar Urethane is ideal for sealing outdoor furniture, but it yellows the finish. So, only use it over stain. Pick a good water-based poly to protect over paint.

This cedar and painted pine mix is my favorite. But, you can save about $100 by using all pine. πŸ™‚

I used Red Cedar as the seat and back on my bench, mainly because I had the Live Edge Cedar already and wanted to carry that wood to the seat. 2×6 Red Cedar costs about $20 per 8’ board, that’s $100 to $120 total for 5 or 6 boards. 2×6 pine costs about $4 per 8’ board, that’s just $20 to $24 total for 5 or 6 boards. So, the total lumber costs for Pine with Cedar will be $130 to $150. And, the total lumber costs for all Pine is just $50 to $54. I just thought I’d point that out before you buy.

Now, let’s get to the DIY Outdoor Sofa from 2×4 build!

Steps to Build this 2×4 Wood Sofa

Step One – Cut and Resaw your Lumber

First, use your Miter Saw to cut the pieces for your bench sides. You’ll need 10 pieces: 4 – 28” long with 45 ends, 4 – 23” long with 45 ends, and 2 – 25” long with 90 ends.

Next, resaw both 1 ½” sides (edges) of your cut 2×4’s on your table saw.  You want to remove the rounded corners. Take about ¼” off each side. You want the final width of the boards to be 3” wide. Use a newer table saw blade with a high number of teeth to get the smoothest result when resawing. You can see me doing this step in the build video.

Step Two – Assemble the Sides

I used wood glue, strap clamps  and my brad nailer to join the outside square sides of this DIY Outdoor Sofa from 2×4. Then, I used Kreg pocket holes and wood glue to join the 25” board. That board should be 12” from the inside of the square (13 ½” up from the ground). This board will hide the ends of your seat frame and should be flush with the edge of the frame.

Once the glue dries on the sides, use wood filler on the pocket holes and joints. Let that dry then sand the sides smooth with 100, 120, and 150-grit sandpaper.

Step Three – Build the Stretcher

Cut 2 – 25” lengths and 1 – 72” length of your 2×4’s. Then resaw the 72” board to 3” wide, to square off the edges. And, just this time, resaw the 2 – 25” lengths to 2 ½” wide. Cutting these boards slimmer adds more depth and detail to the sides. It’s just a design element.

Mark the middle of the boards to make it easy to center the 72″ board on the stretcher with the side pieces.

Step Four – Join the Stretcher

Use 2 Kreg Pocket Holes on each end of the 72” board and wood glue to join it with the 2 – 25” boards. Center the 72” board on the 25” boards. Join the 3 boards, then sand them smooth with 100, 120, and 150-grit sandpaper. It’s easier to sand what you can before assembly.

Then you’ll use 2 pocket holes on the 25” board ends and wood glue to join the stretcher to the bench sides. You can HIDE ALL OF THOSE pocket holes by joining everything upside down. Turn the sides upside down and the stretcher upside down.

If any of these steps are confusing, download the printable plans to see more diagrams of the DIY Outdoor Sofa from 2×4 build. The bottom the stretcher should be 6 ½” up from the inside of the frame (8” up from the ground). MAKE SURE that the flush side of the 25” board (in blue) in the middle of each side is ON THE INSIDE of the bench.

Step Five – Build the Seat Frame

Cut 2 – 72” long boards and 4 – 21” long boards on your Miter Saw. Then resaw those to 3” wide. Join the 21” long boards to the 72” long boards with wood glue and Kreg Pocket Holes (in grey). 1 – 21” board should be flush with each end of the 72” boards. The other 21” boards are 18” in from each side. Join the 6 boards, then sand the seat frame smooth with 100, 120, and 150-grit sandpaper before attaching it to the sides.

The blue pocket holes are used to join the seat frame to the bench sides. Again, I recommend keeping all of the pocket holes on the bottom. So, attach the seat frame to the sides upside down for the nicest result.

That bench seat frame should be even with the bottom of that 25” board in the middle of each side. That way that 25” board hides the frame and the bench seat boards that will sit on top of it.

Step Six – Build the DIY Outdoor Sofa from 2×4 Bench Back

Cut 1 – 69” board, 2 – 15” boards with 45-degree ends and 2 – 72” boards with 45-degree ends. Then resaw them to 3” wide.

Step Seven – Join the Bench Back

Glue and screw the 69” board to the 15” sides first with 4 pocket holes. Doing this part first lets you keep those pocket holes on the bottom side of the bench back. Then glue, clamp, and brad nail the top and bottom boards on to the bench back. Again, sand this bench back smooth with 100, 120, and 150 grit, once the glue dries and you can unclamp it.

I attached my Kreg Jig to my bench back after building it, to drill the pocket holes.

Step Eight – Join the Bench Back to the Frame

Use glue and 2 Kreg pocket holes on each side of the bottom of the bench back to attach the bench back to the sides. It’s not shown in the drawing, but I slightly angled my bench back to make it more comfortable to sit in. All you need is a little angle to make it more comfortable. Check out this photo of my DIY Outdoor Sofa from 2×4 to see the angle on my bench back.

Step Nine – Finish this Frame

Use wood filler on all of those pocket holes and anywhere else that might need it. Let that dry, then sand everything to 180-grit with a sanding block. You should paint or stain the frame now. You can see the steps and how-to video for the Blue Distressed Paint Finish I used here. I finished and sealed every part of this frame, top and bottom. That sealer helps to protect the bench from rain, snow, humidity, and any other moisture that it might be exposed to.

After planing and sanding my cedar 2×6’s.

Step Ten – Prep your 2×6’s

If you use 2×6 Cedar, it comes pretty rough. You’ll need to sand it smooth. Or, you can save a lot of time using a planer. I used my Dewalt Hand Planer to smooth out all 4 sides. Then I cut them to size and prepped them for finish by sanding them with 120 and 180-grit.

If you are using 2×6 Kiln Dried Pine, Fir, or similar, cut your boards to size and prep them for finish by sanding them with 120 and 180-grit.

The opening between the 2 sides should be 72”, I’d cut your 4 or 5 seat boards to 71 ¾”, That’ll leave an 1/8” gap on either side. Cut the board for the bench back to the exact width of the frame (should be 72”) or 72 ½” to have a pretty ¼” overhang on either side of your DIY Outdoor Sofa from 2×4 bench back.

Step Eleven – Attach the Bench Back Board

I attached my back with 2 corner (angle) brackets. 1 on each side. You could also put one in the middle. Clamp the board in place before attaching the brackets. That’ll hold it tightly in place while you screw everything in. It’s easiest to attach the brackets to the bench frame first, then clamp the bench back in place and screw those into place. Drilling pilot holes will make the job easy.

Step Twelve – Attach the Seat Boards – With Cushions Option

If you plan to always have cushions on this bench, or if you just prefer this look, you can go for just 4 boards across the seat. I’d leave an 1/8th inch gap on each side when you cut your seat boards. So, 71 ¾” boards in the 72” opening between the sides.

Have all 4 sides and the ends sealed before attaching. Start the first board ¼” back from the front of the sides. Leave a ¾” gap between each board. Use exterior screws or glue and brad nails to attach the boards to the frame. You can fill the brad nail holes with a matching wood putty, for a cleaner look.

When you build the With Cushions option the gap on the back of the bench is bigger.

Step Twelve – Attach the Seat Boards – Without Cushions Option

If you won’t be using cushions on this bench, or if you just prefer this look, you can use 5 boards across the seat. I’d leave an 1/8th inch gap on each side when you cut your seat boards. So, 71 ¾” boards in the 72” opening between the sides.

Have all 4 sides and the ends sealed before attaching. Start the first board ¼” back from the front of the sides. Leave a ¼” gap between each board. The 5th board should be cut to just 4 ½” wide, before sanding and finishing. Use exterior screws or glue and brad nails to attach the boards to the frame. You can fill the brad nail holes with a matching wood putty, for a cleaner look.
