Pillowflex Synthetic Down Pillow Insert 19x19 in (for 18x18 sham) — Karate-Chop, Hypoallergenic Loft

Pillowflex's 19x19 in synthetic down pillow insert (recommended for 18x18 shams) is a plush, hypoallergenic filler that gives accent pillows a full, high-end look without animal down.

This Karate Chop pillow insert from Pillowflex is a resilient, American-made synthetic down alternative designed to create the rounded, full silhouette shoppers expect from designer throw pillows. Filled with sustainably sourced polyester fibers and wrapped in a soft poly-cotton shell, the insert balances loft with support so covers sit smoothly and keep shape through everyday use.

How should I size this 19x19 insert for my pillow shams?

For a tailored, overfilled appearance measure your pillow sham corner-to-corner and choose an insert slightly larger than the cover size. This 19x19 insert is intended for an 18x18 sham to achieve that plump, karate-chop finish.

• Measure corner-to-corner of your sham, pulling fabric taut.
• Choose an insert 1–2 inches larger than the sham for a full look.
• Use the 19x19 insert with 18x18 shams for optimal fullness.
• Return to a same-size insert if you prefer a softer, less filled look.

What makes the Pillowflex synthetic down filling different?

The Pillowflex fill imitates the fluffy, lightweight feel of natural down while avoiding animal-derived materials. Its fine polyester fibers trap air for loft and compress back to shape, delivering a down-like drape without feathers or allergens.

• Cruelty-free, odorless polyester fiberfill for consistent loft.
• Lint- and dust-resistant construction for cleaner pillows.
• Designed to compress and recover, preserving the pillow's silhouette.
• Manufactured without flame-retardant chemicals.

How do I care for and maintain this pillow insert?

This insert is designed for easy upkeep; spot clean or machine wash on a gentle cycle and tumble dry low to restore loft. Fluffing after washing and occasional air-drying keep the fill evenly distributed and the pillow looking fresh.

• Machine wash gentle, cold water; tumble dry low with tennis balls.
• Spot clean stains promptly to prevent set-in marks.
• Fluff regularly to maintain the karate-chop silhouette.
• Avoid bleach and high heat to protect the shell and fill.
