Don't let saggy, deflated cushions convince you it's time for a new sofa! Based on helpful community discussions, there's a fantastic and accessible DIY method to restore them to their former glory. While one of the provided sources was not specific, the other points to a highly effective and popular solution that can completely transform your furniture.
The most popular and effective trick is to re-plump your existing cushion inserts with polyester quilt batting, which you can find at any craft or fabric store. Simply unzip your cushion cover and remove the foam block inside. Then, wrap the foam with one or two layers of high-loft batting, trimming it to size. A light spray adhesive can help keep the batting smoothly in place. This adds a wonderful layer of loft and firmness right where it's needed, reviving that supportive feel you've been missing.
The final step is to carefully work the newly thickened insert back into its cover. It will be a snug fit, but that tension is what gives the cushion a full, like-new appearance. For cushions that are truly beyond saving, you can also replace the entire foam insert or add fresh poly-fil stuffing. This simple project can completely rejuvenate the look and feel of your sofa, making it comfortable and inviting once again without the major expense of a new one.
