You wouldn't buy a mattress without knowing what's inside, right? Same goes for cushions. At Cushion Source, your fill options aren't just "fluffy" or "firm" - they're tailored for how and where you sit. Whether it's your porch swing, window seat, or favorite spot to collapse after a long day, what's inside your cushion really does matter.
Seat cushions need to be firmer than back cushions. Your back needs light support, but your backside needs real structure. The heavier load demands a firmer fill.
Thicker cushions feel firmer, and thinner cushions feel softer or squishier - even with the same foam. More fill means more resistance to compression, so always consider thickness when choosing fill firmness.
Batting is a thin polyester wrap added to foam to:
Note: Not recommended for outdoor cushions (especially with Reticulated Foam or CumuPlush) as it can retain water.
Foam is a popular choice for seat cushions because of its structure and long-term comfort - but when it comes to outdoor use, there's something you need to know.
Foam loves to hold onto water. If your cushions get caught in a heavy downpour, that foam can soak it up like a sponge - and unless it's able to fully drain and dry, that moisture can lead to mold or mildew over time.
So what's the fix?
If you're using foam outdoors, especially in uncovered areas or rainy climates, we strongly recommend adding a protective liner. It's a breathable fabric layer that helps block moisture from soaking into the foam. It won't make your cushions waterproof, but it will give the foam a better shot at drying quickly and lasting longer.
Of course, if your space is covered, you live in a drier area, or you bring your cushions in when storms roll through, foam without a liner can still be a solid choice. It's all about how you use your space - and how much effort you want to put into babying your cushions.
