What are the best pillow insert sizes for 18x18 and 20x20 covers?

For a full, plush look, choose an insert 1–2 inches larger than the cover. For an 18×18 cover, use a 20×20 insert. For a 20×20 cover, use a 22×22 insert. If you prefer a softer, looser look, you can match insert to cover size.

How do down and down-alternative pillow inserts compare?

Down offers a soft, luxurious feel but can flatten more easily and may not be ideal for allergy-sensitive households. Down-alternative (like Foamily’s hypoallergenic polyester) mimics down’s softness while holding shape better, is easier to maintain, and is more budget-friendly.

Where can I buy affordable pillow inserts near me?

Shop directly at Foamily.com for affordable, made-in-USA pillow inserts and multipack sets. Foamily products are also available on major online marketplaces. For in-person shopping, check your local home goods or craft stores for basic polyester inserts.

How do I choose firmness for throw pillow inserts?

Choose firmness based on purpose and fill. For structured decorative pillows, use firmer fills like polyester or foam and size up 1–2 inches. For softer pillows or lounging, opt for down or softer fills and match insert to cover size for a relaxed look.

What are the care instructions for polyester and down inserts?

Polyester (down-alternative): Machine wash cold on gentle cycle and tumble dry low. Add dryer balls to help fluff; do not bleach or iron. Down/feather: Spot clean or wash per care label; dry completely to prevent clumping; fluff regularly. Store inserts in a cool, dry place.

I recently upgraded all my throw pillows with this American-made pillow insert, and it completely transformed the look and feel of my home. It’s truly the best pillow insert made in the USA — soft, supportive, and beautifully crafted.

From the first touch, you can feel the difference in quality. The hypoallergenic filling gives the perfect balance of comfort and structure, so the pillow stays plump and supportive without flattening over time. The 100% USA manufacturing also means it’s made with higher-quality materials and craftsmanship you can trust.

The stitching is durable, the insert holds its shape perfectly, and it fits snugly inside both decorative and everyday pillow covers. I also appreciate that it’s easy to replace and refresh, which makes it ideal for seasonal décor changes.

If you’re looking for a premium, long-lasting insert for your couch, bed, or decorative pillows, this one checks every box. It’s the kind of product that reminds you why Made in the USA still stands for quality and care.

✅ Key highlights:

Proudly Made in the USA

Keeps shape and fullness over time

Whether you’re an interior designer, a homeowner, or just someone who loves a cozy, high-quality pillow, this is easily the best pillow insert made in the USA — and it’s worth every penny.

Comfortable

Lightweight. Comfortable. Easy to clean.

Great support pillows

I was surprised when I first received the pillow because it was shrink wrapped and folded, but after making a slit in the pastic I watched as the pillow expanded and turned into a solid, supportive pillow.

Well constructed

Softness, well constructed

Don't Let The Package Fool You

When this first arrive I was for sure it was the wrong size, it was going to be too thin, and it was not going to be comfortable. I am so happy to be wrong, trust the process, let it air out, and it is perfect, phew! I have tried many other throw pillows that just are not comfortable. When I think of throw pillows I think of a pillow you can grab randomly and lay down on and be able to take a nap. If you do not have that kind of throw pillow, your throw game is off and wrong.

Sure throw pillows add the decorative touch of a home, but serious I am looking for pillows that I can nap on, these are some great throw/nap pillows! Would highly recommend, again, trust the process, let it expand and fluff and it will be great.
