Tutorial (Easy to Make Window Seat Cushion for IKEA Trofast Storage)

Here comes the promised step-by-step tutorial for how to make a window seat style cushion for the top of IKEA's trofast storage!
(You could do this for any flat bench though!)

(The fabric cover for the cushion is removable and involves no zipper)

Here's what we did:

1. I wanted a 2 inch thick cushion, but it was way cheaper to buy a big piece of 1 inch foam and double up (once you have the two pieces on top of each other, they don't slide around)

2. I bought fabric (I guessed on the amount- get enough to wrap around your foam like you're wrapping a gift)

3. When you get home, cut the foam to the size of the top of your bench (you can cut 1 inch foam with a pair of scissors)

4. Lay the foam on top of the fabric and wrap the fabric around the foam (like wrapping a gift) and make sure you have an overlap on top of the foam. (I made the fabric cover kind of like a pillow sham, so that you can take the cushion in & out, to wash the fabric. The overlap will not be sewn- it will be the opening for the foam)

5. Cut any extra fabric off (use the above picture as a guide to see how much fabric you need on the ends, taking into account that you'll be folding the edge over and pressing it as shown below)

6. Fold the ends (as shown above) and press. When I did mine, I worked it out so that the part that goes lengthwise across the cushion is the selvage, so it didn't need to be folded & pressed to finish it.

Time to Pin

7. Now we'll fold & pin the corners. Fold your first corner up (as shown in the photo below)

8A. Pin into place as shown. (you can pin right into the foam if that helps)
8B. Un-pin the part shown in 8B (you don't have to pin & then un-pin it, I just did that to show you closely how to pin it so that you can do the next fold)
8C. Bring the fabric up as shown, so that you have a straight line across the top edge & side edge.
8D. Pin into place & repeat for the other corners.

9. Pin the edges up as shown:

Okay, now you're done pinning- yay!
Time to SEW!

Sewing Steps

You're going to sew by hand, and you're going to sew the foam right into the cover (don't worry- you can get it out later- I've already had to wash my cover once!)

1. Start at the top corner of one end. Tie a knot at the end of your thread and start (I tried to show you in the photo below)

2. Do a blind stitch (as shown below) to close up the side and top edges of the ends of the cushion.

3. Now you're done sewing!
Here's what your little overlapping pillow-sham-like opening will look like:

And here's the finished project!
A cute little seat for my girls to read on... or put their dolls to sleep on :)

I hope this tutorial was easy to follow- let me know if I need to clarify anything!

  7. I've been scouring websites trying to find ideas with Ikea products on how to make a window seat for my daughter and this is perfect! Do you know what the weight limit would be? Thanks so much for sharing!

  8. Sorry Kym, I'm not sure about a weight limit. I'm glad you found the tutorial helpful!

  9. Kym, we have one of these Ikea benches, and my 200+ lb husband sits on it. We have the wood version (pine). They also have a white particleboard version that isn't nearly as sturdy.

  11. Great tutorial! Found you via sugar and dots, hope you have a lovely day!

    1. Super cute, and easy! Thanks! My husband and I just finished building a 14 foot window seat in our girls' bedroom, and I've been looking for a simple method for covering a cushion. I think I just found a winner. =)

    3. Michelle, I'm glad you think it will be helpful! :)

  12. Awesome! I can't wait to make one for the play room!

  13. Where did you find the foam that you used ?

    1. I found the foam at a fabric/craft store called Lens Mill

  14. You are a genius! That is the neatest and easiest way to make a cover I've ever seen! - Jaime (thriftaesthetic.wordpress.com)

  15. I know this is an old post but I just wanted to say a big THANKS! I've been searching for a tutorial just like this but everything involved zips, piping or staples. I knew what I wanted to do but couldn't figure out how to do it, thanks to your tutorial I can now get on with it :o)

  16. i dont understand how its a slip on cover when its sewn into the actual foam? if you wanted to wash it you would have to undo everything ?

    1. Hi Charlotte,

      The case opens like a pillow sham opens (you can see a photo of it at the bottom of the tutorial- the second to last photo in the post). No un-sewing required :) The foam is flexible enough that you can get it out through that opening and get it back in again after washing.

  17. What a cute little seat!! Love the extra storage!! We so need one of these in our girls room.

  18. great look and well done

  19. Hey this is great! I've been hanging on to some couch cushions to repurpose! I didn't have it in me to toss them when the rest of the couch went (it was in rough shape, but not the cushions) and I also have a great window that would be the perfect spot for a cushioned seat for reading with my girl! Just need some nice fabric to use and I'm set!

    Thanks for the inspiration!!!! and the tutorial :)

  20. This is so pretty! I noticed you didn't use a board under the foam and I was wondering if that was necessary at all but now I see you don't need it. Thanks, Im always looking for ways to cut corners and time lol. I'm master craft cheater!


Thanks for taking the time to leave a comment- I love reading them! :)
