The provided context from the search results was not relevant to the question of how to fix flattened sofa cushions. Therefore, this answer is based on general knowledge of furniture and upholstery care.
Restoring flattened sofa cushions can significantly improve the comfort and appearance of your furniture. The appropriate method depends on the type of cushion filling and the degree of flattening.
For a simple and immediate improvement, start by fluffing the cushions. If your cushions are removable and filled with a loose material like feathers or fiberfill, you can often revive them by unzipping the cover and manually breaking up any clumps in the filling. Vigorously shaking and patting the cushions can also help redistribute the filling and restore some loft. Regularly flipping and rotating your cushions is a crucial preventative measure to ensure they wear evenly and stay plump longer.
If fluffing is not enough, you may need to add more filling. For cushions with a solid foam core, you can enhance their fullness by wrapping the existing foam with a layer or two of polyester quilt batting. This adds a soft, crowned top and fills out the cover more effectively. Simply remove the foam core, wrap it snugly with the batting, secure it with a light spray adhesive if necessary, and reinsert it into the cushion cover. For cushions with loose filling, you can purchase additional fiberfill, down, or foam clusters to mix in with the existing material until the desired firmness is achieved.
For cushions that are severely compressed and beyond the help of extra batting, the most effective solution is to replace the foam insert entirely. You will need to measure the length, width, and thickness of your existing cushion cover to purchase a new foam core of the correct size. Opting for high-density foam will provide firm support and greater longevity. After acquiring the new foam, you can cut it to size if needed, wrap it in batting for a professional finish, and carefully insert it back into the cushion cover. This method essentially gives you a brand new cushion.
