Pillowflex Synthetic Down Pillow Insert 20x20 in — Karate Chop Firm Loft, Hypoallergenic

The Pillowflex 20x20 Synthetic Down Pillow Insert (Karate Chop Pillow) is a firm, feather-free decorative and sleeping insert that replicates classic down loft while remaining hypoallergenic and made in the USA.

Designed for people who want the look and loft of real down without feathers or allergens, this 20 x 20 inch insert uses premium polyester fiber to deliver cushiony support and a smooth silhouette for shams, throw pillows, and bedroom styling. The crisp white poly-cotton shell resists odors and is sewn to create an even, full shape that holds up to everyday use.

How do I pick the right size for my pillow sham?

Measure the sham from corner to corner — not along the seam — and choose an insert slightly larger than that measurement so the cover looks plump and tailored. Pulling the outer seams tight when measuring helps ensure the insert fills the edges for a neat finish.

• Measure across the diagonal corners for accuracy.
• Pick an insert a bit larger than the sham for a full appearance.
• Use the provided size chart image to match dimensions.

What makes this a good option for allergy sufferers?

The Pillowflex insert uses non-allergenic polyester fibers instead of feathers, reducing exposure to common triggers associated with natural down. The materials are free of flame-retardant components and designed to minimize dust and unwanted odors.

• Feather-free polyester fill to limit allergens.
• No added flame retardants that can trap dust or smells.
• Poly-cotton cover for a cleaner sleep surface.

How firm and lofty is the ‘Karate Chop’ construction?

Marketed as a firmer alternative to standard down, the Karate Chop Pillow keeps a strong profile and resists flattening, making it suitable for both decorative use and side sleepers who want consistent support. The dense polyester fiber offers a springy feel that recovers quickly after compression.

• Firm, resilient fill that holds shape.
• Quick loft rebound for maintained appearance.
• Suitable for shams, toss pillows, and supportive use.

Where is this pillow insert made and how is it constructed?

• Made in the USA — Palmetto, GA production.
• High thread-count poly-cotton shell for softness and durability.
• Evenly distributed polyester fiber for consistent loft.
