How to Attach Batting to a Foam Cushion

Adding a layer of polyester batting to a foam cushion creates a soft, plump cushion. It also helps to round the edges for a great-looking cushion and masks any imperfections, dips or jagged cuts in your foam. Batting also helps fill in any gaps between the foam and cushion cover, creating a tight cover with no puddling or sagging. Watch our short and handy video to see how easy it is to add batting to a foam piece for a cushy and super comfortable seating cushion.

Once you cut your foam to size, use the foam as a template to cut the batting. Cut the batting with a 1" overlap on all sides. The overlap will help round the edges of the cushion for a nice, smooth appearance once the cushion cover is on. Make sure you only wrap the batting around the top, bottom and one side of the foam. Keep the other side clear for the zipper. You don’t want the batting to get caught in the zipper teeth when opening and closing the cushion cover.

To glue the polyester batting to the foam, you need a good spray adhesive. At Sailrite®, we sell several spray adhesives that are perfect for this type of application. In our video, we use 3M™ Super 77™ Spray Adhesive (#636100). This aerosol adhesive bonds materials quickly with a very strong hold. It’s great for a variety of applications and bonding uses. Another recommendation is the newer CushionRite® Foam & Fabric Spray Adhesive (#125476). This product offers quick tack, is repositionable if needed, and is designed specifically for bonding foam, fabric and batting. CushionRite spray adhesive is recommended by Sailrite for gluing sheets of CushionRite foam.

Make sure you've allowed your spray adhesive to fully cure so the batting is glued permanently to the foam. It's also a good idea to put cardboard, or something sacrificial, down before spraying to protect your workstation. We also recommend working in a well-ventilated area.

Once the batting is glued in place, simply insert the cushion assembly into the cushion cover — and that’s it! That’s all there is to creating a soft, comfortable cushion seat with a nice-looking rounded edge with batting. Watch our video below to see a demo of this process.
