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.
