Examine the sofa pillows closely to make sure the material has no frayed ends and that the covers are sewn on securely.
Place the pillows into the dryer and set it to low heat. Allow them to remain there for approximately 10 minutes. You can also add a dryer sheet, if desired, to freshen the fabric. A few clean tennis balls can help fluff feather pillows.
Remove the pillows from the dryer and fluff them liberally with your hands.
Fluff the sofa pillows with your hands once every one to three days to maintain their appearance.
Toss them into the dryer about once each month to keep them from developing a crushed appearance.
