Best Pillow Inserts 2026: Decorative & Throw Pillow Fillings Reviewed

What Are Pillow Inserts

Pillow inserts are the inner fillings used inside decorative pillow covers, shams, and throw pillowcases. Unlike sleeping pillows, which are designed for head and neck support, pillow inserts are primarily for aesthetics, back support while sitting, and adding texture and dimension to a room. They come in standard sizes from 12x12 inches up to 28x28 inches, with square, rectangular, and round shapes available. Learn more in our comprehensive guide to Pillow Fill Guide 2026: Memory Foam, Latex, Down, Buckwheat & More.

The right insert should be slightly larger than the cover for a full, plush look. A common rule is to use an insert 1-2 inches larger than the sham. For example, an 18x18 inch cover looks best with a 20x20 inch insert. Materials include polyester fiberfill, down, down alternative, foam, and memory foam.

Best Pillow Insert Overall: Foamily Premium Hypoallergenic

The Foamily Premium Hypoallergenic Pillow Insert uses a virgin polyester fiberfill that resists clumping and maintains loft. The cover is a poly-cotton blend that is durable and holds its shape. It is available in 10 sizes from 12x12 to 28x28 inches. The fill is dense enough to create a full look in decorative covers but soft enough for lumbar support. It is machine washable and budget-friendly.

Best Down Pillow Insert: EuroSquare White Goose Down

The EuroSquare White Goose Down Insert is filled with 650 fill power white goose down. It offers the plush, compressible luxury of down in a decorative format. The 100% cotton cover is down-proof.

Best Memory Foam Pillow Insert: Milliard Memory Foam Pillow

The Milliard Memory Foam Pillow Insert uses shredded memory foam that conforms to the back when used as a lumbar support pillow. It is firmer than fiberfill inserts and holds its shape longer. The bamboo-derived cover is breathable. It is ideal for window seats, reading nooks, and bed backrests where structural support matters more than pure decoration.

Best Budget Pillow Insert: Fixwal Throw Pillow Inserts

The Fixwal Throw Pillow Inserts are a two-pack of polyester-filled inserts at a low price point. The fill is less dense than premium options but adequate for seasonal or temporary decor.

What to Consider Before Buying Pillow Inserts

• Size: Choose an insert 1-2 inches larger than the cover for a full, tailored look.
• Fill type: Polyester is affordable and easy to wash. Down is plush and luxurious. Memory foam offers structural support.
• Firmness: Overstuffed inserts create a crisp, full appearance. Softer inserts look more relaxed and casual.
• Shape retention: Down and memory foam hold shape better than low-density polyester, which can flatten over time.
• Care: Machine-washable inserts are practical for high-use areas. Down inserts usually require dry cleaning.
• Allergies: Choose hypoallergenic polyester or down alternative if you have sensitivities.

When to Upgrade From Inserts to a Real Pillow

Decorative inserts serve a purpose, but if you find yourself using throw pillows for actual sleep support or lumbar comfort every night, it may be time to invest in a purpose-built sleeping pillow. Premium sleeping pillows use engineered fills and ergonomic shapes designed specifically for spinal alignment and pressure relief.

FAQs

What size insert should I buy?

Buy an insert 1-2 inches larger than your cover. An 18x18 cover needs a 20x20 insert for a full look.

Can I wash pillow inserts?

Polyester and down alternative inserts are usually machine washable. Down inserts should be dry cleaned or professionally laundered.

Are pillow inserts the same as throw pillows?

No. The insert is the filling. The throw pillow is the complete item with a decorative cover over the insert.

Why does my pillow cover look flat?

The insert is probably too small or has lost its loft. Try a larger insert or replace a flattened one.

What is the best fill for pillow inserts?

Down for luxury, polyester for practicality, memory foam for support. Down alternative balances luxury and easy care.
