18x18 Throw Pillow Inserts 4-Pack - Hypoallergenic Soft Polyester

In this review of the 18x18 throw pillow inserts 4-pack, the bottom line is simple: these are a reliable, budget-friendly choice for anyone who wants consistent loft and a comfortable feel in standard square covers. Crafted in Toronto, the inserts combine a plush but supportive fill with a durable non-woven cover, making them a good match for living rooms and bedrooms where easy care and hypoallergenic materials matter. They deliver on fit for 18x18 covers and expand quickly out of the packaging, so the primary reason to buy is dependable sizing and soft, machine-washable comfort.

Key Features

• Made in Canada: Manufactured in a Toronto facility with inspection at each stage to ensure consistent quality and build standards.
• Correct sizing guidance: A sizing chart and clear guidance help shoppers pick the right insert size, suggesting 1 in larger for covers under 17 in and 1-2 in larger for covers 18 in and above.
• Hypoallergenic fill: Filled with 100 percent brand new high loft polyester fibers that resist allergens and aim to stay fluffy after unpacking.
• Durable outer covering: A non-woven polypropylene outer layer adds strength and holds the filling in place for long-lasting use.
• Machine washable: Designed for easy care on a gentle cycle and safe in the dryer on low heat with tennis balls to restore loft.

Who It's For

These inserts are well suited to homeowners and renters who need a consistent, affordable solution for 18x18 pillow covers on couches, sofas, and beds. They are particularly good for people who want a hypoallergenic option that expands quickly and keeps a plush but supportive shape in shams and decorative pillows.
