Wrap the foam with multiple layers of batting. A small amount of spray adhesive applied to the foam can help the batting stick to it so it stays in place once you put the covers back on. If possible, have someone help you put the covers back on the cushions. All those layers of batting make it a tight fit- but that is what you're looking for, so ask someone to lend a hand to make your job less painful.
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 you’ve got a plain Jane sofa and you want it to look more formal a surefire way to do it is to add some nailhead trim. Simply determine the lines of the sofa you want to accent and then nail in the tacks (try to place them at even intervals of roughly ½ inch). Just be sure to choose a solid part of the frame so you’ve got a solid foundation to nail the trim into. And it should go without saying that you cannot do this on a slipcovered piece – only on one that’s upholstered.
