How to Replace Stuffing Inside Sagging Couch Pillow

Look at the enclosure on the pillow. If it has a zipper or flap enclosure, simply open the pillow and pull out the old stuffing. If it has a seam, choose a corner and gently rip out a few stitches with the seam ripper -- the hooked end acts as a knife to cut the thread holding the two pillow sides together. Make certain you are not damaging the material, and continue to remove stitches until you have a big enough hole to remove the old stuffing easily.

Wash the pillow material. While some fabrics lend themselves to machine washing (look for cleaning instructions on the pillow or the couch, if the fabric matches), you may wish to handwash the fabric in a mild soap and warm water. If necessary, pretreat any stains with a stain remover first. After soaking and rinsing, wring the water out gently and either hand-dry the material, or dry it on a low-heat cycle in the dryer.

Iron the pillow cover if it is wrinkled or puckered after drying. Use a low setting on the iron to ensure that you do not scorch the fabric. Mist with water to attain a smooth surface.

Place the stuffing in the pillow, making sure to push it into the corners for square or rectangular shapes. Separate any clumps of stuffing to avoid lumps on the exterior. Fill the pillow until the desired plumpness is reached; make sure no stuffing is leaking out of the pillow.

Close the opening of the pillow. This can be done either by closing the premade attachment, such as a zipper; gluing the two sides of the pillow fabric together with craft glue; or sewing it shut with a slip stitch. Thread the needle, and put a knot in one end. On the inside of the pillow fabric, make a tiny stitch that goes through both sides of the fabric. Pull tight, and repeat to close the pillow. Clip the remaining thread with scissors. Fluff the pillow and place it back on the couch.
