The Design Confidential Free DIY Furniture Plans and How to Build a Reef Sectional Sofa Corner Chair

So in all of my genius glory it appears that I posted the armless unit for this fab reef sectional sofa, and then forgot to draft plans for the corner unit. Yahoo. Well today we rectify that crazy and we give you… wait for it… the corner unit! I bet you weren’t going to guess that, eh? What say you? Do you prefer your sectional sofas with all working parts and plans? Thought you might…

To view the other plan for this pair and to build an actual sectional sofa, you will want to visit the plan for the Reef Armless Unit and the cushion options here that will work best are the Outdoor Deep Seating Cushions which retails for $29 and two or three 18″ toss pillows for the back. Alternatively you might also use a cushion like this for the seat which retails for $19 and would help cut cost in a large quantity but it is decidedly less boxy than the other for sure, so this is a style and budgetary choice that can be made and it is yours to make my friends!

As with all of our plans, you are building at your own risk and you should have a firm understanding of building in general before you attempt many of our plans (some are easy as pie and perfect for beginners). With that, go forth, have fun, take lots of pictures and share them in a showcase or on social media with the hashtag #builtTDCtuff and we will share our faves!

Cut the pieces for two of the Back Legs, the Front Leg, and Sides. Set the Kreg jig for 1-1/2” material and drill pocket holes in each end of the Sides and in the tops of the Back Legs. For one side of the chair, assemble the Back Leg, Front Leg, and Side as shown with glue and 2-1/2” pocket hole screws. For the other side of the chair, assemble the Back Leg and Side as shown with glue and 2-1/2” pocket hole screws.

Cut the pieces for the two Tops, the Corner Back Leg, the remaining two Back Legs, and the Front Apron. With the Kreg jig set for 1-1/2” material, drill pocket holes in both ends of the Front Apron and in the top end of the Corner Back Leg. Assemble as shown with glue and 2-1/2” pocket hole screws.

With the Kreg jig still set for 1-1/2” material, drill pocket holes in the top ends of the two remaining Back Legs. Assemble the other Top to the two remaining Back Legs as shown with glue and 2-1/2” pocket hole screws.

Assemble the pieces as shown with glue and 2-1/2” pocket hole screws. Attach the second Top to the Corner Back Leg with 2-1/2” wood screws, if needed (depending on where you drilled the pocket holes on the Corner Back Leg, you may need additional reinforcement).

Cut the pieces for the Center Seat Support, the Seat Support, and the Seat Support Extension. The Center Support will be a 2×4 ripped down to 2-3/4” wide and will be located 3/4” down from the top of the Sides to allow for the Seat Slats. With the Kreg jig set for 1-1/2” material, drill pocket holes in both ends of the Center Seat Support, Seat Support, and Seat Support Extension. Assemble as shown with glue and 2 1/2” pocket hole screws.

Cut the pieces for the Seat Slats. Set the Kreg jig for 3/4” material and drill pocket holes in each end of the Seat Slats. Attach the Seat Slats to the Seat Support and Front Apron with glue and 1-1/4” pocket hole screws. Secure the Seat Slats to the Center Seat Support with glue and 1-1/4” brad nails.

Cut the pieces for the Back Slats. The angles may be a little tricky but they should be cut at approximately 25 degrees. (see drawing). Once the angles are cut, set the Kreg jig for 3/4” material and drill pocket holes in both ends of each Back Slat. Attach to the Seat Support and Top with glue and 1-1/4” pocket hole screws.

  1. Rayan,

    Love the Reef Corner and Reef Armless plans. I’ve tried different computers and cannot see the pictures associated with each step. Any chance you could look into it?

  2. Hi! Just wanted to flag a problem we had with these designs in case any one else tries the same thing. We love the plans and are building a big sectional with two of the reef sofa plans (modified to be one right-arm and one left-arm unit) and one corner unit. I stupidly assumed that, since they were all designed for the same Target cushions, they would all fit together. But we realized after building one of the sofa units and starting on the corner that they are not the same depth. The sofa is several inches deeper than the corner unit (and the armless unit, according to the plans on the site). We also found that the Target cushions are too shallow for the sofa unit. I think you would need at least a 25-inch-deep cushion, probably a little deeper. But I can’t find any that would fit and it would be really expensive to make our own, so we’re just going to live with the gap and adjust the measurements for the corner unit. If we had noticed from the outset, I would have wanted to modify the sofa plans to fit the 24-inch Target cushion, but it’s too late for us. Hope this helps someone else avoid the same mistake!

    1. eek! i think you may have accidentally built from some of the ‘modified’ plans and some that are standard to the original inspiration dimensions. i originally designed the pieces to be similar in size to the inspiration pieces. once it became one of our most popular plans, i redesigned the pieces and posted a second grouping of them specifically to work with the target cushions (i think they are 24×22 or something along those lines). i am so sorry this happened and i am thinking i need to make all the plans and their coordinating pieces MUCH more clear and obvious. so sorry for the inconvenience this has caused you guys. i know it is costly and irritating.

  3. Hi,
    i was so happy to find your plans. My Wife has seen them and wanted 2 corner pieces and one single chair. Since I live in Austria, I have to use other (metric) dimensions, cause we do not have the 1×4 or 2×4 in Stock. Futhermore our cushions are a diffent size (got mine from Ikea with 65x65x15 cm) and my wood is now 40x80mm and 19x80mm. I will just start at the first front Leg and will work my way to the back. hopefully it will end up well :-))) I might send you a picture and if anyone needs the metric dimensions, just leave a post. I will measure it after I’m finished :-))

  4. Done!! With a few modifications. What a wonderful Idea from you.
    1) I let the Back Leg away, since i just screwed the joining top with 120mm long wood screws together.
    2) Since my wood was 19×80 mm for the seat and back slats, I used 5 instead of only three
    3) I used the cushions from Ikea
    4) I inseted two smaler slats right in the corner (from left to right) so that the cushions won’t slip through.
    If it is ok with you, I would post a few pics on pinterest and would set your Url into the reference Links list..
    Thx again for the graet Idea!
