Add a hint of beachiness to your porch swing or living room sofa with this set of 2 square throw pillows. These matching pillows are made in the USA and feature a solid-hued cover complemented by piped edges in a different color. They have weather- and stain-resistant Sunbrella covers that are sewn closed around recycled polyester filling. Plus, these pillows are reversible, so they look great no matter which way you turn them. We love how this set looks on a patio bench or poolside conversation set.

These are lovely little pillows that add a pop of color to our gray patio seating. They are a beautiful powder gray blue that could complement many different color pallets. My only concern is that the covers are sewn on and cannot be removed for cleaning. Otherwise a perfect outdoor pillow.. Tracey. Greensboro, GA. Fri Jul 31 2026

20"H x 20"W, Brannon Redwood Sunbrella®

Bring all-day comfort to your patio, porch, or sunroom with this square throw pillow made with durable Sunbrella performance fabric. The bold striped cover is woven from Sunbrella performance fabric, a solution-dyed acrylic that resists fading, water, mildew, and UV rays so the pattern stays crisp through full-sun summers, surprise rain showers, and salty coastal air. This throw pillow is built to fit a wide range of indoor/outdoor furniture, making it a smart pick on Adirondack chairs, patio sofas, porch swings, and sunroom benches for a quick refresh that holds up through summer storms. Inside, a generously filled polyester core keeps the cushion plush and prevents the flat-pancake look that comes from cheap fills. The cushion is reversible, so you can flip it weekly to even out wear and extend its life across multiple seasons. Spot clean with mild soap and water and let air-dry — the fabric is designed to handle rinse-and-dry care without losing its finish. The insert is included, so it arrives ready to use right out of the box. Designed and constructed for outdoor use, so the comfort you set out in spring is still there at the end of the season — ready for next year's patio season too.

The piped edges offer a sophisticated touch, making it the perfect addition to any seating area. Plus, it's UV, moisture, and mildew resistant, so it stays vibrant and inviting year after year.

The good *This pillow has a Sunbrella brand label sewn on it. This means it will hold up fantastic in harsh Florida weather. * It is indeed blue (a dark smoky blue). And it is 22” as advertised. The not-so-good *While it is a nice tonal (blue on blue) fabric with a slightly raised texture, it is certainly not boucle. Boucle as most people know (since it has become extra trendy) is a looped fluffy material.. Sarah. Wellington, FL. Fri Aug 25 2023
