Over time, your prized sofa can get lumpy. The seats, once fluffy and soft, can just be hard and uncomfortable. Rather than call an upholsterer or other furniture expert, you can revive your sofa cushions easily and extend its lifespan by restuffing them or replacing their batting. For the most part, depending on your couch, you may not even need sewing experience to finish this project.
Unzip your cushion or use the seam ripper to open your sofa cushion.
Measure your sofa cushions using the tape measure. You will want to measure all the way around lengthwise and widthways.
Measure out the thick flattened batting using the measurement in Step 2. Add a 5/8 inch seam allowance to both ends.
Pull your sofa cushion pillow out from its cover and lay it on the batting.
Cover the pillow as if wrapping a gift. Sew the batting down where the 5/8 inch seam allowances meet.
Fold the batting over the side of the pillow, and sew it down using the needle and thread.
Put the newly covered sofa cushion pillow back into its cover and pin the open edge together.
Use the needle and thread to sew the open section back together using a slip stitch or zip it closed, if the cover has a zipper.
Stuff the batting into the sofa cushion between the pillow and its cover if using loose batting.
