How To Make Your Own Cube Cushions

So what are cube cushions? I’m not talking about big square cushions that you use a foot rest. I’m talking sofa cushions to sit on. Made with lots of individual cubes.

So Why Cubes?

Well, recently I decided to build my own furniture, a corner piece to be more precise. I am still in the process of completing this project. Winter came and went, then Summer came and work got in the way and so far I have still only reached the point of it being square storage boxes, with legs. I have still got a long way to go.

Anyway, having a couple of old cushions and lots of old duvets scattered over to make it more comfortable, to be honest, was starting to frustrate me. All the bits and pieces to tidy and rearrange on a daily basis.

So I decided it was time to start making some cushions. But I did not want to pay for foam at around £200. I put on my thinking cap. Fiber stuffed cushions should work out cheaper, but they have this horrible habit of sinking in the middle, so I didn’t like that option. 

Then ping…..How about….

Cube Cushions

If I make lots of cubes and stitch them together, there will be less chance of them sagging. Also, I could leave a way to add extra stuffing in if I needed to. I knew that I had lost of scrap material and lots of cushion stuffing from the old cushions so away I went. This is how they turned out.

Sofa Cube Cushions Tutorial

You will need:

  • Random Fabric – lots, nothing stretchy, thickish cotton works best.
  • Cotton Thread – lots
  • Scissors – nice and sharp
  • Sewing Machine – preferably
  • Tape Measure
  • Stuffing

Sizing Your Cube Cushions

To begin you need to decide the size of the cushions you want. Mine were 27″ x 27″ x 6″ deep.

Decide how many sections you intend to make, I decided to go 4×4. 
So I ended up with needing 16 cubes, each measuring 6.75″ x 6.75″ x 6″ deep for each sofa cushion.

Cutting The Fabric Pieces

Before you begin merrily cutting out your squares, remember that you will be stitching these together so add a half inch all round.

If you are following me exactly, you will be making 16 cubes per cushion.

You will on my measurements need 32 squares at 7.75″ x 7.75″. That’s 16 tops and 16 bases.

Then you will need 4 sides for each cube. So 64 side panels at 7.75″ x 7″.

Mark Mark Up Your Stitch Lines

This of course if optional, but it does make the job whole lot easier.

Draw a line half inch in from the edge on the inside of the fabric.

Let’s Get Stitching

Take the 16 bottoms and stitch a giant buttonhole from one side to the other. (See image). This will be used for filling teh chushions.

Next, take a top and stitch it to the long edge of one of the sides.

Tip – stop at the corners where the mark lines cross, DO NOT go all the way to the end.

This will enable you to snip the pointy bit off, which will give you nice sharp corners.

Continue stitching on the sides till all four are joined.

Next, stitch down the sides. So that it looks like an open box. Then stitch on the bottom. You should now have a cube with the seems outside.

Cut a line through the middle of the zip stitching on the bottom and turn right way out. There you have it, your first cube.

Repeat until you have 16 cubes.

Join It All Up

If you’ve managed to get this far well done, but there is still a way to go.

Now, all you have to do is stitch all the cubes together. This you will have to do by hand. Using over stitch. You will need to first join all the top edges, then the bottoms and then the side around the edges.

Stuff Your Cushion

Once all the cubes are stitched together you can fill you cube will any filling you wish, hollow fiber is probably the best as it will give you a smoother finish. Place a flat piece of cloth inside the hole to hold the filling in.

Here is how you cushion should now look.

So there you have it, Cube Cushion.

I have now had this cushion for about four months and have found that it has held up really well. As you may be able to see in the photo, I could do with going back and restitching a little on the joins. But it has coped excellently with my two dogs.

As a project to make, I would definitely say it is not a quick fix, it does take a lot of time and effort to make, but for me it was worth it.

The great thing is, you can adjust and re-adjust the filling to how hard or soft you want it. You can also take it apart and wash it all and re-stuff whenever you wish.

I hope you have enjoyed this tutorial, please feel free to send me photos of yours if you try it out.
