If you're unable to reach up into the corners, a tool or something like a ruler wrapped with a soft towel will help to send the fill up to round out any sunken edges. I used a cordless telephone. True story. Add filling until you can't add anymore, and then add more. Continue to add fill as you back your hand out of the cushion, making sure there is a decent amount down by the zipper -you don´t want what you stuffed up in the top of your cushion to all settle to the bottom.
Your final product will end up looking really puffy and overstuffed, but the fill will start to settle after a few weeks, so you want to pack it as full as you can. Next, move on to the seat cushions. Remove the cover and set to the side, and vacuum the cushions to get rid of any deteriorating foam.
If your sofa is looking saggy there’s a good chance you can make it look better by stuffing the cushions. Now don’t just shove a bunch of cotton batting in there because it will result in a lumpy cushion. Instead, take off the cover (most sofas these days have removable covers) and wrap the cushion in a layer or two of quilt batting or foam wrap. If you find it shifts around a bit secure it using a spray adhesive. And if you find there are still a few saggy spots, now is the time to fill them with extra pieces of cotton batting. Easy peasy.
