Before you start, remove your jewelry, especially rings. I almost lost mine in the process! To give yourself room to work on the seat backs, remove all the seat cushions and set them in a clean workspace. Grab a large amount of Poly-fil and begin to shove it up inside the cushion, making sure to position it behind any foam or pillow that may already be in the cushion.
For a modern, clean look, try placing pillows in contrasting shapes right beside each other on one side of the sofa. The consistency in color ensures continuity. Try clustering trios of geometrically-patterned pillows together. Space them out between each sofa cushion for a look that’s anchored, yet casually rustic at the same time.
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.
