Fix Sagging Sofa Cushions

When the hubs and I got married and bought our first house, a million years ago, we were excited when the time came to buy new furniture (oh how things have changed). We needed new everything to furnish our home and that included a sofa. Neither one of us had ever purchased furniture before, and we were young and broke, so we went for cheap and as close to good looking as we could get for the money. We eventually learned that when you buy a cheap sofa it doesn’t last long, so, when it was time to buy the next sofa, we did a little research first and spent a little more. Long story short, we gradually worked our way up to a well-made sofa that would last many years.

How we fixed our sagging sofa cushions (in 75 seconds)…


Flash forward to the present day and our Pottery Barn sofa. We’ve had it for 13 years now and it’s moved with us, from Florida to Illinois and now to North Carolina, and has held up very well. Recently though, I’d noticed that my back was hurting when I sat on it.

It’s gotten a lot of use from our family and the result was sagging sofa cushions, 13 years of butts plopping down on it will do that. Once I figured out it was the cushions I knew it was time to get them replaced. Of course, being the cheapskate DIYer that I am, I wanted to try to figure out a way to do it myself and I’m glad I did because it turned out to be an easy fix.

 Use this genius idea to quickly and easily fix sagging sofa cushions with new foam.

This project was actually done a few months ago when we lived in Illinois but, because of the move, I wasn’t able to put the post together until recently. Little did I know when I did this that we would move into a house with a living room that was too small to accommodate my beloved sofa, so my loss will be someone else’s gain.

A genius idea to quickly and easily fix sagging sofa cushions with new foam.

Anyway…the old foam was wrapped in a down cover but I decided to go with batting wrapped foam. Upholstery foam is expensive but new down covers were outrageously expensive, and I was tired of pulling feathers from the old ones, so I went with a high quality batting wrapped foam.

Shopping for the foam took some time. I researched and looked at a lot of websites and once I settled on a shop that I liked, I made exact measurements from the sofa cushion covers and had the foam cut to size and wrapped in batting. They were delivered to me all ready to go. Like I said, it was expensive, at $173 for two cushions, but I got a really good quality foam that should last years.

How to quickly and easily fix sagging sofa cushions with new foam. Genius! chatfieldcourt.comSo, how did I get that big, cushy piece of foam in the cover, you ask? Painter’s plastic and a vacuum. Yup, that’s it. 20 seconds and the foam was in the cover. I figured that a video would show the process better than photos so, with the help of my trusty assistant, we made one.

If you’d rather have a blow by blow, here is how we did it.

Step by Step Instructions:

  1. Take the painter’s plastic and spread it out.
  2. Place the foam on on half of the plastic and pull the other half over to cover the cushion completely.
  3. With your hand, push all of the air out and tuck the plastic around the cushion.
  4. Next, take your vacuum and put the nozzle under the plastic against the cushion. The cushion will quickly compress.
  5. Remove the vacuum nozzle and quickly place your compressed cushion in the sofa cover.
  6. As the cushion inflates to its original size, work with the cushion to get it in the cover so there are no lumps or bumps.
  7. Pull the plastic out, it will rip and tear but it will all come out, and zip it up.

Voila…a new cushion that looks like it was professionally done.



Can you believe how quick that was? And super easy, too. The cushions look like new again and will last for years. Now it’s ready to go to a new home (sniff, sniff). Anyone in the market for a sofa with brand new cushions? ๐Ÿ˜‰

Genius! How to quickly and easily fix sagging sofa cushions with new foam.

    Genius! Love the video too! Question? Where did you buy the foam? Did you have to cut it on your own?

      Thanks Vel. I shopped around and ended up ordering my foam from DIY Upholstery Supply. I made exact measurements from the sofa cushion covers and had it cut to size and wrapped in batting. Hope that helps.

    Thank you so much for this post! I have a 5 year old sofa that I paid a lot for and it is stuffed with down. However, it is always loosing feathers and the cushions always look so messy. I love the sofa and do not want to get a new one, so I’m going to try this. Thanks so much for the great tutorial! I hope that you have a blessed day and a wonderful week!!!

      Thanks Shannon! I thought I would love the down but, you’re so right, it looked messy and there were always feathers popping out. I don’t miss them one bit. ๐Ÿ˜‰

      Thanks for stopping in.

    What a great idea–and your helper was super efficient. LOL
    Did you sell the couch yet?

      Yes, my helper is very efficient. I haven’t sold my sofa yet. I’m just getting ready to list it on Craigslist. Do you want to buy it? ๐Ÿ˜‰

    I tried this with my old Bassett sofa. The cushions were just awful, and when I chose new foam cushions I overcompensated for the sagginess and they ended up as hard as a rock. I’m sorry you have to get rid of your sofa, it’s beautiful!

      Thanks, Anne. I’m sad to see it go but it’s just too big.

      So sorry that yours didn’t turn out the way you had hoped. I was nervous about that very thing but I think it’s good. They are definitely firm compared to what they were, but I think it’s comfortable.

      I appreciate your visit.

    Where did you find the foam inserts? I have no idea what to look for when purchasing cushions.

      Hi Lou Ann. I had no idea when I started looking. I just kept researching and looking at different kinds of foam. I knew that I wanted something that would last so that’s what I concentrated on. At first I looked into down cushions/inserts, but once I saw the prices, I changed course. I would suggest you just read up on the different types of upholstery foam and zero in on the firmness that you want and a price range. I ended up buying mine at DIY Upholstery Supply. Hope this helps.

    I never would have thought of compressing with a vacuum! I have a large chair that has down cushions and it also sags. I will try your method. Thanks!

    Hi Kristi,
    Thanks for the video! How did you get the plastic to seal around the edges so you could use the vacuum? I’m intrigued! It worked brilliantly though!
    Thank you, Cheers, Liz.

    • Kristi
      Tuesday,July 26, 2016 / 12:52 am

      Hi Liz. We didn’t do anything to seal it, just pressed the air out and made sure that the plastic was snug against the cushion. The video is pretty accurate on exactly what we did. It’s amazing to see it work like that, and that it was so simple. Hope this answered your question.

    I wish I knew this when I had my camper. New cushion were very expensive. How did you seal the painters plastic around the cushion?

    • Kristi
      Tuesday,July 26, 2016 / 12:57 am

      No seal around the cushion. We just made sure the air was out and pushed the plastic against the cushion. The vacuum formed, well…a vacuum in the plastic and compressed the cushion. Amazing and it worked like a charm.

  9. Monday,July 25, 2016 / 10:48 pm

    That is a great idea. We just got new cushions for our sofa. I am saving this for when I have to get new ones again. Instead of wasting money I can do this. Thank you.

        I agree. have cushions on a couch, love seat, chair set in my sunporch that every year need to be washed (dogs). I have to time it to when my brother visits, because he’s the only one that can fold the foam in place and hold it with one hand while slipping on the cover with the other. Next time, I’m trying this. Hope it works with old foam — don’t see why it wouldn’t. Thanks so much! Norma (I piggy backed on this post — hope no one minds!)

          No problem with piggy backing a comment, Norma. I appreciate your visit and comment. I think that you could definitely do this on your own. It was really easy to do and only took a few minutes. Let me know how it works out for you.
