A DIY outdoor sofa is a great weekend project for anyone who can use a drill and saw. In fact, you don’t even need to saw if you buy the wood cut to size.
We recently made a wooden patio sofa ourselves.
After stenciling and sprucing our patio up, we wanted a place to sit and enjoy it, but if you’ve ever looked for the best outdoor furniture you will know that it can be just as expensive as furniture for indoors! Paying thousands for an outdoor sofa was not in the budget, so I did some research on building a modern-looking sofa using common lumber and separate cushions.

The great thing about building an outdoor sofa yourself is that it will be custom-made to your space, taste, and budget too! With a little research, I was soon inspired for this easy DIY project and I’d found some budget-friendly cushions to use so I measured up for my materials with those in mind.
It is much easier to adjust your furniture design than it is to make the sofa first, then try and find cushions to fit. The measurements I came up with took into account these woven outdoor cushions from Target (opens in new tab) – I chose three seat cushions, and three backrest pillows (opens in new tab) to match.
I had decided for this piece to sit on our patio which isn’t enormous, but it definitely has room for a cool design feature like this to create an outdoor living space.
DIY outdoor sofa: step-by-step

Skill level: Intermediate
Time: a weekend (to allow for stain drying, but you could be faster if you time it well)
Total cost: $407
Project cost breakdown:
2x4s: $98 2x8s: $64 1x4s $32 Brackets: $21 Sofa cushions: $102 Backrest pillows: $74 Dowel jig/pins: $16
1. Build the sofa arms
I started by first constructing the arms of the sofa. I used common 2x4s cut down to 31 inches. I lined up seven of these and joined them together using a dowel jig (opens in new tab) and dowel pins (opens in new tab).

Once I had three of these sections complete, I stacked them and used 4” screws through all three layers and glued them together using wood glue (opens in new tab).
The sofa arms are made using a total of 21 cut-to-length 2x4s and they are HEAVY!!
I let them dry overnight, and clamped them into my pipe clamps (opens in new tab). In the morning, I gave them a thorough sanding using 60-grit sandpaper (opens in new tab).

To make the arms look complete, I wrapped them in 1×4 select pine on all four sides.
I mitered the edges of each piece of pine so they would fit together cleanly. Using my brad nailer, I nailed all the pine pieces to the stacked 2×4 arms.

2. Finish the arms and add legs
I also cleaned up the arms, filling any gaps and nail holes using spackle and stainable wood filler (opens in new tab) and, you guessed it…. more sanding! I sanded the whole thing down using a higher grit (up to 320 grit) at each pass until the wood was completely smooth and there was no chance for splinters in these sofa arms.

The last thing I needed to do for the sofa arms before staining was add furniture legs for stability. Using a scrap piece of wood I created a jig by drilling with a 1” spade bit (opens in new tab) hole into the scrap and clamped the jig to the bottom of my sofa legs and drilled and screwed in the felt furniture legs (opens in new tab) that act as levelers.

3. Stain or paint the sofa legs
I stained the sofa legs using my tried-and-true staining method….1:1 ratio of stain to polycrylic. The mixture allows me to stain and seal in one application. This was the only part of the sofa that I stained because it will be the only visible wood.

4. Create the seat and backrest
Now I needed to join the arms together and create a platform (or place to sit) for the sofa cushions. I used three 2x8s cut to 67 inches for the seat and brackets to hold them in place.

The brackets were screwed to the sofa arms with 2” wood screws and then underneath the 2×8 seat. I used the same brackets, installed at a 30% angle for the back rest.

5. Add the cushions and style it up!
I used tan sofa cushions because I live in the dusty desert but also added a fun touch with accent pillows and a throw that can be washed.

This outdoor sofa is so sturdy and heavy and cost me a fraction of what a traditional outdoor sofa would cost me if purchased retail.

Customising your patio couch
This step-by-step is a great starting point for you own DIY outdoor sofa. The basic design can be adapted to suit your space – just remember to measure up for off-the-peg sofa cushions first to keep the costs down, unless you are thinking of making your own (which is easy enough if you have a sewing machine).
One idea would be to use a pair of wooden planters instead of making the arms yourself. Simply skip to step four after staining your planters if needed.
Alternatively, your could also use one planter and two arms to make a corner sofa, using the planter as the corner piece.
