How to stuff sofa cushions & give new life to a saggy couch!

Since being pregnant, I have really increased the amount of time that I spend laying on my couch.

We have had this couch for only about 3 years, but it hasn’t held up.

As my friend told me, “buy cheap and weep”. The sofa has just really not held up well and is saggy and you can feel the metal springs in your butt when you sit down.

I desperately wanted to buy a new sofa, but Sean shot that down completely.

He describes the couch as “totally fine” and while I can usually convince him to change his mind, he was not going to allow me to buy a new couch without it becoming a big fight.

In the interest of our marriage, I decided to pursue options for reshaping and fluffing our existing sofa to make it more comfortable for my tired third trimester and a maternity leave of nursing a baby.

I did a little research and decided to order some new foam and stuffing to try to replenish the saggy pillows.

I spent about $100 on replacement foams for this project.

In the above photo, you can see the original cushions on the left and the re-stuffed cushions on the right.

This process will definitely make couch cushions look tighter and more full! It’s a great way to make your couch cushions firmer.

What to use for couch stuffing

To re-stuff seat cushions, you should use high-density foam.

Of course, you can use any sheet of foam, but you don’t have much space inside the cushion cover, and regular foam doesn’t give much cushion per-inch. High-density foam is more expensive, but you will really feel it!

To re-stuff pillows, you will want to use polyfil. This is like traditional pillow fill and is easy to add by the hand full. This is also the best filling for sofa back cushions.

Where can you buy foam for seat cushions?

You can get high-density foam at most craft and fabric stores. I prefer to order on Amazon since it’s convenient and they have easy free returns!

What you need to stuff sofa cushions


How to re-stuff sofa cushions

STEP 1: REMOVE & CLEAN

First, remove your cushions and clean the couch. I vacuumed under each cushion (there was a lot of dirt + sand in there).

I also lint-rollered all of the pillows and cushions.

This is a great time to tighten the legs of your chair or throw any pillow covers into the washing machine for a really fresh start.How to stuff sofa cushions remove sofa cushions from their covers

STEP 2: REMOVE A SEAT CUSHION

Start with a seat cushion. Unzip the cover and pull out the insert.

STEP 3: MEASURE

Measure the length and width of the cushion. Cut that size of foam.

STEP 4: CUT THE FOAM

Cut a piece of foam to the size of the top of your cushion. You can use sharp scissors or an electric knife if you have one.

STEP 5: ADHERE THE FOAM TO THE CUSHION

Use spray adhesive to attach the foam to the top of the cushion.

Follow the instructions on your can of spray adhesive and give it time to dry – you’ll be glad that you did!

STEP 6: REPLACE THE CUSHION IN THE CASE

Insert the cushion back into the cover. This might now be a really tight fit.

Go slowly so you don’t damage the cover and it can help to have a second set of hands! Zip up the cover and you are done.

STEP 7: REMOVE THE BACK PILLOW

Now address the seat back cushions. Unzip each cover.

STEP 8: ADD POLYFIL

Add polyfil to the side of the cushion that will face your back.

I used about 2/3 of a 20oz bag on each seat back. Be sure to shove it into the corners and edges and then zip the cover back.

STEP 8: REPLACE THE PILLOW

Replace all of your cushions and repeat until you are done! Your couch should now look a lot tighter and less saggy and feel a lot more comfortable to sit on.
