ACCENTHOME 18 x 18 Outdoor Pillow Inserts Pack of 4 — White Water-Resistant Hypoallergenic Square Throw Pillow Fillers

These ACCENTHOME 18 x 18 outdoor pillow inserts (pack of 4) are water-resistant, hypoallergenic polyester fillers designed to keep decorative pillows plump and usable indoors or on your patio.

Lightweight but resilient, these 18 x 18 inch square inserts come compressed for shipping and quickly regain their loft after a gentle fluffing. Made with a water-resistant liner and 7D polyester fiberfill, they aim to resist light splashes and maintain shape for cushions used on chairs, benches, or sofas. The neutral white color works with most covers and the pack of four makes them convenient for updating multiple cushions at once.

How well do these inserts stand up to outdoor conditions?

They are built with an outer fabric and an internal water-resistant liner that helps block light moisture and splashes, making them suitable for covered porches or occasional outdoor use. They are not intended for continuous submersion or heavy rain exposure.

• Water-resistant liner reduces absorption from brief splashes
• Polyester outer resists quick drying and damp odors better than some fills
• Recommended with waterproof covers for extended outdoor durability

Will these pillow inserts keep their shape over time?

The inserts use upgraded 7D polyester fiberfill with tight stitching to provide durable loft and support. The denser fiber helps the pillows stay full and reduces hollowing, but some occasional fluffing will keep them looking their best.

• Tight stitching prevents shift and clumping of the fill
• 7D fiberfill delivers firmer, longer-lasting loft than standard polyester
• Compressed for shipping — tap or knead to restore full shape after unpacking

How should I care for and prepare the inserts after delivery?

These inserts arrive vacuum-sealed to save space during shipping. Allow them time to fully expand and gently pat or shake each pillow to redistribute the fill; spot clean or follow the manufacturer label for washing guidance.

• Remove from vacuum bag and shake to accelerate loft recovery
• Spot clean with mild detergent; air dry thoroughly before using outdoors
• Pair with removable covers to minimize direct exposure and simplify cleaning

What sizes and quantities come in this listing?

This listing includes four 18 x 18 inch square pillow inserts, a common size for decorative throw pillows. Other sizes may be available separately if you need rectangular or larger square options for different covers.

• Pack of 4 identical 18 x 18 inch square inserts
• White neutral color suits a variety of covers and décor styles
• Additional sizes often sold by the brand for mixed arrangements

Who is this for: These ACCENTHOME pack-of-four inserts are a practical choice for homeowners, renters, or short-term outdoor decorators who want ready-to-use, shape-holding pillow fillers for patio seating, porch benches, dining chairs, or indoor decorative pillows. They fit well for anyone seeking hypoallergenic polyester fill, quick loft recovery after shipping, and a versatile white base to pair with seasonal or year-round covers. For heavy rain exposure or continuous outdoor placement, add waterproof covers to extend the life of the inserts.
