20 x 17 Adirondack Chair Cushion - Alana Tile Rain-Proof Comfort

Our review of the 20 x 17 Adirondack chair cushion in Alana Tile finds it best suited for anyone who wants a colorful, lightweight upgrade for standard Adirondack or rocking chairs. The single biggest reason to buy is the combination of a fade-resistant outdoor fabric and an eco-friendly PFAS-Free C0 treatment that keeps the cushion looking fresh through sun and summer use. It is presented as a practical, easy-care option with a thin profile that fits most chairs and offers immediate visual impact and moderate comfort without adding bulk.

Key Features

• Correct fit: The two-piece design delivers a seat that measures 20 in by 17 in and a back that is 21.5 in by 28.5 in, so it fits most standard Adirondack and rocking chairs without modification.
• Weather-aware fabric: The 100% polyester outdoor fabric is treated with enhanced UV protection to resist fading and preserve the Alana Tile pattern over time.
• Sustainable finish: An eco-friendly PFAS-Free C0 treatment reduces harmful coatings while still providing a rain-proof surface for light wet conditions.
• Low maintenance: The cushion cleans easily with soap and water, making seasonal upkeep straightforward.
• Shape retention: Partially recycled polyester fiber fill helps the cushion retain shape so it does not collapse immediately after a few uses.
• Secure fit: An elastic strap on the back keeps the cushion positioned on the chair during normal use.

Who It's For

This cushion is ideal for homeowners who value color and UV resistance in outdoor textiles and who use Adirondack or rocking chairs primarily for casual seating on a porch, patio, or deck. It is especially suitable for buyers who want an eco-friendlier surface treatment and easy cleaning rather than heavy-duty marine-grade protection.

People who need thick, highly supportive cushions for long sessions, or who expect substantial structural reinforcement for elderly users, may want to consider a thicker, more robust pad. Also, if you require heavy-duty waterproofing for exposure to prolonged rain, a fully waterproof, thicker alternative would be better.

Pros & Cons

Pros

• Attractive Alana Tile print with strong color retention thanks to UV protection.
• Eco-friendly PFAS-Free C0 treatment offers rain resistance without PFAS coatings.
• Fits most standard Adirondack and rocking chairs and stays in place with an elastic strap.
• Easy to clean and filled with partially recycled fiber that helps maintain shape.

Cons
