How to restuff my non-removable sofa cushions?

I found this on Hunker.com Step by step how to for you. Hope it helps, sounds like a lot of work but if you have the time would save you from buying a new sofa.

Step 1

Spread open the crack behind the couch cushions. Cut along the crack as deeply as possible in a location where it is the least noticeable. Spread the fabric apart and look inside the couch. Sever the couch cushions from their interior attachments if necessary.

Step 2

Slide a plywood board the same size as the seat of the couch in through the hole in the fabric and underneath the cushions. Arrange the plywood so that it is evenly situated and cannot be felt by someone sitting on the couch. Cut the plywood smaller if necessary so it does not protrude beyond the cushions.

Step 3

Close the cut in the fabric by securing it with safety pins along the length of the cut then shove the cut deeply into the crack behind the cushions and pin it down to make it less noticeable.

Replacing the Couch Fabric

Step 4

Flip the couch upside down and pull all of the staples out of the base, ripping any seams if necessary or cutting the fabric with scissors to remove it. Continue to remove the fabric from the entire couch by pulling staples, ripping seams and cutting fabric. Pull up the cushions, cutting them from their attachments if necessary and slide a plywood board the same size as the cushion area underneath the cushions.

Step 5

Spread out the fabric and measure it. Cut a new piece of fabric for the couch that is at least one full yard larger than the old fabric. Lower it over the couch and loosely position it so that it covers the entire couch. Attach it in the cracks around the cushions with staples while stretching the fabric tightly.

Step 6

Continue to stretch the fabric taut over the sides, front and back of the couch, stapling whenever possible in inconspicuous areas. Flip over the couch and staple the fabric to the base of the couch about 2 inches in from the edge all the way around, stapling every 4 inches. Cut out any extra fabric with the scissors.

My cushions have a zipper at the bottom. I unzip and push the stuffing up. Then add more to the bottom. It gets messy because of static cling, but they get stuffed. My dog likes to sit on the top of the couch so I punch them from the bottom up to fluff.

Search for the last place in the construction process. You will probably have to put the sofa on its back. Hopefully the cushions are just stapled shut. Carefully remove the staples put in the new stuffing and restaple with a heavy duty stapler.

Your only hope is to see if you can rip out the seams and hope there's a seam allowance, so you can re-stuff then sew shut. In addition to stiffer foam, wrap his cushion with batting to make it stiffer.

If you could match the fabric, you could make a new cushion and install a zipper to facilitate future repairs.

This is my life due to boys and now babies. Well,its already sagging so get brave you can go from underneath r perhaps the side. I have used old pillows or foam from Walmart, basically anywhere. My couch now has a piece of plywood that happened to fit under cushion and-old flattish pillows! Its a little more stuffed in the center as this is where people tend to sit. I have done this with my leather sofa and many others. BTW, the one I have now had "curb appeal" as in, it came from someone's curb!

Under cushions, place a piece of plywood just a little smaller by an inch all around. Also there are commercial braces that can be purchased. I, in the past have also put a layer of poly-fill sheeting (purchase at fabric store). It comes in different thickness and firmness. Wrap the cushion interior with it and sew all edges closed stitching by hand. Stuff it back into the cushion cover and voila no more sag.

The sides seem to be less noticeable if you are going to cut open and resew after re-stuffing.

I agree with Ken - find a hidden seem in the back, cut the stitches and fill it that way. Then use upholstery strength thread to sew it back up.

It has to have a hidden seam or else it would not have been stuffed to begin with. Go to the back and carefully cut open the seam, it maybe hard to get to, have patience. Only open a small enough are to add stuffing to your desired thickness, it will pack down again over time. Resew the opened stiches with upholstery thread. You can also buy curved needles to make this project easier.

If you don't have a zipper, if you have any sewing skills, you could open the seam and add a cut to size mattress topper but then you would have to hand sew it back. I use them in my upholstery projects as well. I used a mattress foam topper in this project that I was re-upholstering because the existing cushions lost their oomph.

If you don't care about cost though and you want it to be easier than having to cut foam to size, I did find a product right off amazon but you would have to do the same thing as I described. Open the seam and insert this. Sew back up.

Do you want the cushion insert changed or just add filling? Pick an area you can hide a seam or reopen a seam. Use upholstery type stuffing or foam rubber for the best result. Depending on which you decide on, will determine the size of your opening. For fiberfill stuffing,

, you can shove it in by the handful, pushing it firmly in the area furthest from you, working towards the opening. In dollmaking, I use forceps, a chip stick, a pencil eraser, or a skewer to stuff it in firmly and so can you. A dowel works, too. Gold luck!

Hi Pat. If there is no seam on the seat cushion, you might have to go in from the back. The backs of most sofas are stapled down. You can remove these upholstery staples with a screw driver. This should give you access to the cushion from the back. A few years ago I had a new sofa that needed repairs. I watched how he pulled out part of the back. Did the repair and stapled the back into place.
