Why is good looking modern outdoor furniture always so expensive?! My biggest pet peeve is paying thousands for outdoor furniture that’s basically in it’s prime for a few short months. I looked high and low for an outdoor furniture set that wasn’t going to break the bank and stay within my project budget, but that literally does not exist. So I decided to make my own DIY modern outdoor sofa!
This was the inspiration piece from World Market and this one too behind the idea of my DIY modern outdoor sofa! I love the modern lines and wanted to make something that was similar but still matched the DIY modern outdoor chairs.
How to make your own DIY Modern Outdoor Sofa
Be sure to read through the instructions thoroughly and FAQ’s on our DIY Outdoor Furniture.
Step 1: Build arm base
If you built the DIY Modern Outdoor Chairs, then these first few steps will be very similar! Cut your arm base pieces using a miter saw and the 1x3x8 select pine boards. By cutting all of these pieces at once you can also make all the pocket holes for the arm bases as well! Cut 4 pieces at 26 1/2″ and 4 pieces at 30″.
Make your pocket holes using a Kreg Jig! I use the the Kreg Jig K4 and absolutely love it. Set your drill guide to 3/4″ thickness and a screw length of 1 1/4″. The pocket holes will ONLY go into the 26 1/2″ boards.
Step 2: Attach arm base seat mount
Cut 2 more 26 1/2″ boards from the 1x3x8 for the center base mount. Measure 10″ from the bottom of the 30″ board and attach the 26 1/2″ board with pocket holes facing inward.
Attach the 26 1/2″ board to the innermost side of the arm rest frame. You may want to use some scrap pieces to brace the piece while you attach. Don’t mind some rogue pocket holes, this was a learning process and I made a few errors while building!
Step 3: Attach seat frame
Use (2) 1x3x6 @ full length for both the front and back of the sofa to form the seat frame. Make 2 pocket holes on each end and face pocket holes inward to hide when attaching. The frame will be very delicate, so use some assistance when flipping over and attaching 1x3x6’s.
Step 4: Attach 2×2 slat supports
Cut a 2x2x8 @ 72″, you may need to cut to fit. This will be a snug fit and you may need a hammer or mallet to push into place. The 2×2 should be lined up with the bottom of the 1×3. Attach the 2×2 with (10) 2″ wood screws on each side.
Step 5: Attach middle brace
Attach (2) 10″ 1×3’s to the middle of the seat frame. Only make pocket holes on one end of the 10″ pieces (don’t mind my rogue pocket holes). You must attach the (2) 10″ pieces first before the 26 1/2″ piece.
Attach the 26 1/2″ board on the underside to hide the pocket holes.
Step 6: Attach seat slats
Attach the 20 – 1×2 seat slats at 25″, again, measure to fit if needed! Use wood glue and 3/4″ brad nails for each slat. Evenly space out the slats at about 2 1/4″ apart, the back and front slats will fit snug against the 1×3 seat frame.
Step 7: Attach back slats
Attach the back slats with 1x3x6 @ full length. Each slat should have 2 pocket holes on each end attached with the pocket holes on the inside. I used scrap 1×3’s as spacers between the back slats.
Step 8: Attach back slat brace
Attach a 1×3 @ 17 11/16″ board to the middle back slats. Use wood glue and a brad nailer to secure. In the spaces behind the 17 11/16″ board attach 1×3 @ 2 1/2″ with wood glue and brad nails.
Step 9: Finished product
Now it’s time to stain the sofa! I used the same stain I used on the chairs on the sofa, a new stain Varathane came out with this year called Flagstone available at Home Depot. Before staining sand with 180G and 220G sand paper and wipe down thoroughly of any dust. For a more in-depth tutorial on staining check out this post here!
This sofa is seriously a dream and I absolutely loved how it turned out!
