The foundation of every cushion project is foam, so it’s important to choose one that suits your needs. The longevity of your project depends on it! When we talk about foam, the term "density" is often thrown around. If you don’t plan on sitting on your box corner cushion frequently, you can use a medium-density foam (sometimes called an occasional-use foam).
However, if you’re looking for a foam that will withstand high-traffic use and last for many years, choose CushionRite® Premium, a high-density polyurethane foam. Luckily, we have an extensive selection of top-quality foam products at Sailrite. Want to learn more about making a cushion? Refer to our informative blog, “Foam Series: Comparing Types of Cushion Foam” (#300053XHT), to more clearly decipher which type of foam is right for you.
Once you’ve chosen your foam, you’ll want to use the handy Sailrite® Fabric Calculator to make your 30-minute box corner cushion. This clever tool will give you the exact amount of fabric needed to cover your cushion foam. Depending on the size of your cushion, you can play with the orientation of your fabric on the calculator so that you’re only using one panel. Having only one panel of fabric to contend with will make the cushion assembly process quicker and easier. Our in-depth video will walk you through the entire process so you’re left with an exquisite-looking box corner cushion!
