How can I make my couch cushions firmer?

Wondering how to make your couch cushions firmer? Your best bet is to re-stuff the sofa by adding new stuffing. This is the best way to make your sofa more comfortable on a budget!

We shared a full tutorial and video that will show you how to re-stuff your couch.

What is the best foam to use for sofa cushions?

You will want to use a high density upholstery foam. You don’t want anything too thick or it won’t fit inside your existing cushion cover.

That’s why the high-density part is important. It is pretty expensive (I think) but is worth it.

Thin, low-density foam won’t make the seat any softer.

This is the foam that I used.

How to make sofa cushions higher

Adding new high density foam to the top of your sofa cushions will raise them 1-2 inches up (depending on the thickness of the foam that you select).

How to fix a sagging couch with attached cushions

If the cushions are attached, you will need to try to figure out how to open them up.

Look underneath to see if there are staples holding them in place.

Pry them up with a flat head screw driver, stuff the cushions, and then re-staple them in place.

How Can I Make Couch Cushions Firmer?

Adding foam is the quickest and easiest way to add firmness back to squished, sagging sofas. Beware: foam can be pricey. Assess the prices before deciding if your couch is worth saving!

How can I re-stuff sofa pillows?

It is easy to re-fluff couch cushions. For sofa pillows, you will want to use Poly Fil. Poly Fil is cheap and easy to work with.

I warn you – you will need WAY more than you think to fill a pillow. Fill it really full and tight or it will look saggy and sad.

How do I keep my couch cushions from sliding off?

If you have sofa cushions that are slipping and sliding around, I suggest adding adhesive velcro to hold them in place.

We added velcro to the cushion on our chaise section of our couch because it was always sliding from side to side and looked horrible.

It worked fantastically!

This would not work if your pillows were reversible or you flipped them often.

If you are wondering what to do when your sofa cushions go flat, I hope that this tutorial helps!
