A sofa that you can build with a fold out seat perfect for storing extra pillows and blankets. Based off a sleeping pad foam cushion, so seating surface doubles as a guest bed.

If you would have asked me even a few months ago about building your own sofa, I would have said, it's not worth it.  Considering the high cost of foam (upwards of $50 a yard) and the cost of fabric (at least $10 a yard for an upholstery weight) I just couldn't see the economics of building your own sofa.

But then I walked past a pile of foam camping pads at a store we have in Alaska called Fred Meyer (owned by Kroger and is kind of a superstore) that were 30" wide, 72" long, and 3 1/2" deep.  And the foam came in soft, medium and firm weights . . . for just $20!  Instantly, the wheels were turning in my head.

Then when my sister Esther mentioned that she didn't have a sofa, and she couldn't find one that was inexpensive, square, and with storage, I was drawing up plans within minutes.  My sister Lydia (we've reupholstered quite a few sofa's together, but never actually built one from scratch) was visiting, and she was just as excited as me.  So we got to work.

And you all know how much I love using paint drop cloths for fabric.  So with some 2x4s, 2x6s, some 2x10s, some 1/4" plywood and alot of worn out pillows and stuffed animals, my sister Lydia and I built a couch in less than 24 hours for about $120.

And by the time we were done, both Lydia and I were making plans to build our own sofas.  Also pictured reclaimed wood carts.

And I just might . . .

Nice clean square design that is so popular right now.  Notice the 2x4 feet.  Please don't notice my messy garage, I was afraid to bring this one inside . . . my sister might not every get her sofa back!  Also, the deep cushions are perfect for sleeping on.

It is after all made from a standard camping pad.  And did anyone notice the little hinges on the front seams?

Big enough to sleep on and with built in storage for the bedding too!  This is my favorite part of this sofa.  You could build it for your office and use it as a reading sofa, then when guests are over, flip open the seat and get your bedding out.  Not shown here, but I did add straps to keep the seat from hinging all the way open and also straps that tuck in the seam behind the seat for easily pulling the seat up.  Just used an old dog leash.

Ready to build your own?  You can do this.

Dimensions
I did a little tweaking on the design to decrease the cost to build (my sister wanted double cushions for the look) and also to increase the storage compartment. The legs above are shown as 2x2s, which you could do but a center fifth leg is recommended. You could also use store bought sofa feet. This sofa is designed around a camping pad measuring 72″ long, 30″ wide and 3 1/2″ deep. You can easily adjust measurements to use a different sized foam cushion, advisably 24″ wide and 72″ long and 3″ or 4″ deep.

Instructions

Step 1

Back

Screw the back together with 3″ screws or 2″ pocket hole screws as shown above. Use glue and adjust for square.

Step 2

Back

Now attach the 1/4″ plywood to the back with 1 1/4″ screws and glue as shown above.

Step 3

Back Batting

Now wrap the back that is not covered in plywood with the burlap and staple in place on the bottom edge. The burlap should be tight. Then use spray adhesive to glue the batting to the back as shown above. Read the direction on the can of the spray adhesive for the best adhesion.

Step 4

Side Batting

Now glue pieces to the ends with the spray adhesive and then trim to fit as shown above. Set the back aside.

Step 5

Step 6

Slipcover

Use the spray adhesive to attach the foam pad to the remaining piece of plywood. Then use the spray adhesive to attach batting to the foam on the top, front and sides. Cut a piece of fabric 73″ long x 31″ wide. Cut two pieces 31″ long x 6″ wide, and two at 73″ long and 6″ wide. Sew together to create a box cushion (see this post for details on sewing). Place the cushion slipcover over top of the foam and staple the slip cover raw edges to the underside of the plywood, hiding edges. This is shown below.

Step 7

That one should be easy. Now cut strips of fabric as shown in the diagram above (step 6) and sew together and staple in place around the sides and front of the sofa. Should be easy to do. Turn edges under to hide raw seams.

Now the back was the most difficult part – certainly not impossible, but I thought was the most difficult part of sewing. To make this part easier, you could simply not put a taper in the back side of the sofa, and all your cuts are square. Anyway, cut out the side and back pieces and stitch together, and fit over the back. Turn under and staple to the underside of the legs. Reference the diagram in step 6 for exact measurements.

Step 8

Base

Build the base as shown above. Don’t worry about the 2x2s not being strong enough – their is no support required here (it’s all in the 2x10s). The 2×2 aprons are to keep the fabric tucked under and to give you something to screw your feet too. Paint or stain your base. If you choose to use 2x4s for the legs, remember, this does change the dimensions of the legs, and adjust the 2×2 cuts accordingly.

Step 9

Assembly

Assembly will be easy. Start by screwing the storage box to the back, through the 2×10 back boards into the supports in the back of the sofa. Use the 3″ screws. Then flip over and screw the base to the sofa underside with 3″ screws. Flip it back over and attach the cushion with hinges. Support the hinges with a strap to keep the cushion from collapsing all the way forward.

Step 10

Pillows

The pillows I sewed for this sofa are square box cushions measuring 36″ wide x 4″ deep x 18″ tall. Cut four pieces of fabric 37″ wide x 19″, four pieces 19″ x 5″ and four pieces 37″ x 5″. Stitch with right sides together, creating a box, but leaving an opening to insert foam. Stuff with loose stuffing. Hand stitch open seam closed.

Wonderful!

Though I'm jealous of those camping pads you found, I've been going through camping sections of stores for quite a while and have never seen such thick or cheap pads as you found, nor would any of the ones I've seen hold up to being in a couch (they were all very thin, squishy, and expensive).

Wonderful!

A suggestion...my store-bought couch has batting wraped around the foam in the cushions. That might tighten up the seat pad and make it even more professional.

Love it! When my daughter gets a bigger bedroom, this will be on a build list for sure! It would be perfect as she hits the teen years! I could also see this transitioning to a college dorm room with ease.

I HEART this ANA!! I agree we need the corner piece to make a sectional! Even if the build cost for the sectional is $350 or even $400 with lumber and fabric it's still WAAAAAAAY cheaper than sectionals that start at $900 without storage! Love it love it! Thanks for all you do, you're such an inspiration!

Thanks for the plans, I plan to build these for our basement!!! I also have 2 suggestions for readers building their own...

- Ebay is a great place to find the foam, but shop around and know what you are buying - prices can vary greatly - we made our own temprapedic mattress from 2 types of foam bought on ebay - queen size less than $200 - as opposed to almost $2000 for name brand.

- New bed pillows work great for the back pillows. Depending upon the length of the couch (I didn't look that closely), either queen sized or king sized pillows would probably work, or even make 3 instead of 2 and use standard size. A standard sized pillow at W-mart or other discount stores are under $4. The other nice thing about using regular pillows is that you can take them out and wash the pillow cover, and could even was the pillow itself separately (following mfg directions) if needed. Unstuffing a fiber filled pillow is a pain, and buying fiberfill can be expensive. You could even go all out and get down/feather pillows!

Oh! you've been teasing me with this couch for days! it looks great and is def. on my list. I had a similar idea to the above poster about the upholstered toddler bed. I"d like to make this L shaped and with arms. I bet the plans for the back could be fitted to make some arms, with enough cushions they could be straight and still be comfortable.

Love these plans though I'm not in a couch needing mode. My college age kids might love it though. We don't have a Fred Meyer where we live but I know our local JoAnn's often has foam 50% which is when I buy it to redo ottoman's that I refurbish from the thrift store. Also our local thrift store sells new mattresses for $80 for a twin. Just an idea for those who need to build a coach. Just love your site Ana. Thanks for all the ingenious ideas.
