Sunbrella Square Throw Pillows Set of 4 - Weather-Resistant 20 in

Our review finds these Sunbrella square throw pillows best suited for anyone who wants durable, colorfast outdoor cushions without fuss. The set of four arrives as zipper-closed 20 in by 20 in covers with hotel-grade, hypoallergenic down-alternative inserts already inside, so the biggest reason to buy is the combination of true-to-color Sunbrella performance fabric and ready-to-use inserts that resist sun and stains. For patios, porches, and poolside seating the fabric's UV resistance and five-year warranty make these a practical, long-lasting choice.

Key Features

• Premium fabric: Sunbrella 100% solution-dyed acrylic is built to be stain-resistant, colorfast and UV-resistant for outdoor use.
• Ready-to-use size: Each pillow measures 20 in by 20 in seam-to-seam with a finished hotel-grade insert, so they are ready to place on seating immediately.
• Hidden zipper: The discreet zipper along one edge allows easy removal of the insert while preserving a clean, tailored look.
• Hypoallergenic insert: The down-alternative fiberfill holds its shape and offers a plush, consistent feel without allergens found in down.
• Easy maintenance: Covers are machine washable on a delicate cycle after removing the inserts, which simplifies outdoor care.
• Hand-crafted: Made at RSH Decor's Upstate South Carolina facility from sourced premium materials for consistent quality.

Who It's For

These pillows are ideal for homeowners and renters who want durable, attractive cushions for outdoor spaces such as patios, porches, and pool areas, and for those who prefer low-maintenance fabrics that retain color in sun-exposed settings. The set-of-four format suits arranging coordinated seating groups or swapping seasonal color accents quickly.

Shoppers who need specialty sizes, custom prints, or firm decorative bolsters should look elsewhere; these are standard 20 in square pillows with medium loft inserts focused on versatility and weather resistance rather than designer-only detailing.

Pros & Cons

Pros

• Durable Sunbrella fabric that resists fading, stains and UV damage for long outdoor life.
• Included hotel-grade down-alternative inserts deliver consistent loft and comfort out of the box.
• Hidden zipper and tailored construction keep a polished look on lounge and dining seating.

Cons

• The set is limited to the standard 20 in square size, so those needing larger or lumbar shapes will need a different product.
• While covers are machine washable, inserts must be removed and air drying is required, which takes more time than fully quick-dry cushions.
