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.
This is what it looked like when I arrived. As you can see, it actually had frown lines and wrinkles. What kind of witchy sorcery did I use to create this magical transformation, you ask? A super top-secret, rare fiber found only in every craft store ever. I used Poly-fil, an easy-to-find, cheap (a 10lb box will run you about $30) blend of polyester that has a high tolerance for wear and tear.
There were many "oohs" and "aahs" from my parents, along with accounts of how much more comfy it felt and how happy they were that they wouldn´t have to think about getting rid of it anytime soon. There was much rejoicing. The two things you need to determine before rushing out to purchase your poly-fil are: a) whether or not the foam in your seat cushions is able to be removed; and b) if there is an access point to the inside of your seat back cushions.
