Pillowflex Synthetic Down Pillow Insert 16x24 Karate Chop — Ultra‑Soft Hypoallergenic Poly‑Cotton

The Pillowflex Synthetic Down 16x24 "Karate Chop" pillow insert is a durable, ultra-soft, allergy-friendly insert designed to give shams and decorative pillows a full, plush appearance.

This 16x24-inch insert is made in the USA with a poly-cotton shell and sustainably sourced polyester fiberfill that mimics the loft and hand of natural down while remaining cruelty-free and free of flame-retardants. It’s designed to pair with a variety of sham sizes for decorative support and everyday comfort, balancing fluffy volume with shape retention for sofas, beds, and accent uses.

How should I size this insert for my pillow shams?

Measure the sham from corner to corner and choose an insert slightly larger than the sham’s nominal size to achieve a full, tailored look. Pillowflex recommends corner-to-corner measurement and selecting an insert that will fill the sham tightly for a plump finish.

• Measure shams across the diagonal for accurate sizing.
• Use this 16x24 insert with 16x22, 15x23, or 16x24 shams for a full appearance.
• Choose an insert 1–2 inches larger than the sham when possible for extra loft.

What is the feel and construction of the Pillowflex Synthetic Down insert?

The insert uses a soft polyester fiberfill engineered to emulate down’s lightweight loft while providing a consistent, supportive hand. The shell is a durable poly-cotton blend that keeps the fill contained and gives a smooth surface for pillow covers.

• Heavyweight, fluffy polyester fiber offers down-like soft loft.
