The easiest and likely least expensive option is to get some new throw pillows. Throw pillows have the power to transform the ambiance in almost unlimited ways. You can play with pattern, shape, size and material. If you currently have something neutral or dark go for bright and bold; if you’ve got a floral pattern try something geometric; and if you have a material that’s rough opt instead for something soft. Throw pillows come in every imaginable style so there’s no limit to what you can do.
My mom was pretty positive there were no zippers to access the seat backs on her sofa, but after a little spelunking she was very surprised to find that, indeed, there were hidden zippers along the bottom back sides. If you can only get to the seat cushion, skip the Poly-fil and just pick up batting. For seat back access only: just Poly-fil.
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.
