MCWPHLS 18x18 Waterproof Throw Pillow Inserts Set of 4 — White, Medium Square, Quick-Dry Plush Support

MCWPHLS 18x18 waterproof pillow inserts are a set of four medium-sized, white square cushions designed to resist splashes while keeping sofa and patio seating comfortable and supportive.

These inserts combine a water-resistant outer fabric with plush 7D polyester microfiber fill to deliver outdoor-ready durability without sacrificing indoor softness. Sold in a convenient pack of four, each 18"×18" insert fits most standard decorative covers and works equally well on couches, beds, patio chairs, or bench seating. The construction emphasizes reinforced edges, breathable polyester, and easy-care maintenance so you can swap covers seasonally and clean spills quickly.

How do these inserts protect against rain and splashes?

The outer layer uses a dense 110g brushed fabric that, together with the interior filling and reinforced stitching, forms a barrier to light moisture and splashes. They are designed to hold up to everyday outdoor use—think brief showers and accidental spills—while keeping the interior fill from becoming saturated.

• 110g thick brushed outer fabric for surface water resistance
• Reinforced edge stitching to prevent seam breakdown
• Quick-dry polyester fiber fill that resists absorbing moisture

Will these inserts feel comfortable on indoor furniture?

Yes—although built for outdoor durability, the inserts remain soft and skin-friendly thanks to hypoallergenic polyester microfiber. They deliver a plush, supportive feel suitable for sofas, beds, and accent chairs while avoiding scratchy or clinical textures.

• 100% 7D polyester microfiber for a soft hand
• Breathable fabric that reduces heat-trapping
• Hypoallergenic materials suitable for sensitive skin

How should I care for and refresh these cushions after use?

The covers are machine washable when removed from pillowcases, and the inserts are designed for easy spot cleaning. Because the set ships vacuum-compressed, allow time for the fill to regain loft—pat, fluff, and leave for 24 hours to restore full shape.

• Spot clean inserts or use gentle machine washing for covers
• Pat and fluff after unpacking from vacuum compression
• Leave inserts 24+ hours to fully recover loft for best support
