When the hubs and I got married and bought our first house, we were excited when the time came to buy new furniture. Like most newlyweds, we needed 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. We eventually learned that when you buy a cheap couch, it doesn’t last long. beige sectional sofa with blue pillows So, when it came time to buy our next sofa, we did a little research first and spent a little more. picture of outside of house and windows OUR EMAILS ROCK! Subscribe to get the latest in DIY Projects and exclusive subscriber access to our Resource Library! Long story short, we gradually worked our way up to a well-made sofa that would last many years. Fast-forward to the present day and our Pottery Barn sofa (similar one, here). 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. Our couch has gotten a lot of use from our family and the result was sagging couch cushions. The back cushions were in good shape but the seat cushions…not so much. I guess it’s only natural when there’s 13 years of butts plopping down on it. Once I figured out it was actually the seat cushions, I knew it was time to look into getting replacement.

Can I replace the foam in my couch cushions?

Absolutely!!! Of course, being the cheapskate DIYer that I am, I wanted to try to figure out a way to do it myself. I’m so glad I did because it turned out to be a really easy fix. sagging couch cushion with blue pillows One thing I did discover was that the original couch cushion foam was wrapped in a down cover. I am always pulling feathers out of the cushion so I decided to go with a batting wrapped foam couch cushion. If you’ve ever bough new upholstery foam then you know it can be expensive but new down replacement inserts were outrageously expensive. 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.

How much does it cost to get new foam for couch cushions?

Buying new foam actually turned out to be a bit more expensive than I had thought. I ended up spending $173 for two cushions, but I got a really good quality foam that should last years. Plus, it was a lot cheaper than replacing the whole sofa, or having a professional fix the saggy cushions. new couch cushion foam on top of sagging cushion
