Arden Outdoor Adirondack or Rocking Chair Cushion 20 x 17 - Rain-Proof

In this review the Arden Outdoor Adirondack or Rocking Chair Cushion is evaluated as a practical, weather-ready upgrade for outdoor seating. The bottom line: this cushion is for anyone who wants a clean, colorful, and low-maintenance pad that fits most standard Adirondack or rocking chairs and holds up to sun and rain. The single biggest reason to buy is the combination of rain-proof, fade-resistant polyester fabric and an eco-friendly PFAS-free treatment that keeps the cushion usable and looking fresh through a season of outdoor use.

Key Features

• All-weather fabric: 100% polyester outdoor fabric is treated with enhanced UV protection to resist fading and maintain color outdoors.
• Eco-friendly treatment: The PFAS-Free C0 treatment provides water resistance without long-lived PFAS chemicals.
• Comfortable fill: Partially recycled polyester fiber fill helps the cushion retain shape and stay comfortable over time.
• Secure fit: An elastic strap on the back keeps the cushion firmly in place on most Adirondack or rocking chairs.
• Easy care: The surface cleans with soap and water, making seasonal maintenance simple.
• Warranty coverage: A 1-Year limited fabric warranty and a 1-Year limited warranty for manufacturing defects offer buyer protection.

Who It's For

The cushion is best for homeowners or renters who want a bright, durable cushion for an Adirondack or rocking chair on a porch, patio, or deck; its fade-resistant fabric and water-shedding finish suit sunny, humid, or occasionally wet climates. It also works well for buyers who prefer lower-maintenance outdoor textiles and want an eco-friendlier water treatment.

Those seeking thick, plush padding or an integrated headrest should look elsewhere, since several users report the cushion is on the thinner side and the top can flop; this product prioritizes weather performance and fit over deep cushioning.
