Adirondack or Rocking Chair Cushion 20 x 17 - Rain-Proof Sapphire

In this review the Arden Outdoor Adirondack or Rocking Chair Cushion is evaluated for everyday patio use and for anyone who wants a simple, colorful upgrade to a standard Adirondack or rocking chair. The cushion stands out most for its weather-ready fabric and cleanable design, making it an attractive choice for households that leave cushions outdoors intermittently; the review finds it especially useful for older users who need noticeable yet not excessive padding and for patios that require fade resistance over a single season.

Key Features

• Dimensions: The two-piece design separates seat and back so it fits most standard Adirondack or rocking chairs and provides a tailored fit for common chair sizes.
• Rain-proof treatment: The PFAS-free C0 treatment gives water resistance without heavy chemical coating, helping the cushion shed light moisture and dry quicker than untreated fabric.
• Fade resistance: The 100% polyester outdoor fabric includes enhanced UV protection so the Sapphire Aurora Blue stripe retains bright color through a summer season.
• Comfort fill: Filled with partially recycled polyester fiber fill, the cushion keeps a soft loft that helps it maintain shape over time while offering comfortable support.
• Secure fit: An elastic strap on the back keeps the cushion firmly in place on the chair, reducing shifting when sitting or rocking.
• Easy care: The cover cleans easily with soap and water, and Arden Selections backs the fabric with a 1-year limited fabric warranty.

Who It's For

This cushion is ideal for homeowners with standard Adirondack or rocking chairs who want an affordable, weather-aware upgrade that looks bright and cleans up quickly; it works well on covered porches, patios, and casual outdoor settings. It is also a good pick for elderly users who benefit from a soft but supportive seat since several customers noted improved comfort.

Shoppers who need thick, heavy-duty outdoor padding year-round or who expect mattress-like thickness should look elsewhere, as some users report the top segment can feel thin or forward-leaning for heavier, long-term use. For full-exposure, long-term outdoor storage without cover, a heavier waterproof cushion would be more suitable.

Pros & Cons

Pros

• Comfort: Many find the cushion comfortable with adequate padding for casual sitting and seniors.
• Color and look: The Sapphire Aurora Blue stripe maintains a fresh appearance after summer use thanks to its UV protection.
• Easy maintenance: Spot-clean with soap and water and rely on the 1-year fabric warranty for defects.
• Eco-conscious treatment: The PFAS-free C0 treatment reduces harmful chemicals compared with older finishes.

Cons

• Thickness and sturdiness: Some users report the top section feels thin and can fall forward, so it may not satisfy those wanting very firm support.
• Not for continuous full exposure: Intended for occasional outdoor use rather than permanent uncovered outdoor placement.
