Sunbrella High Back Chair Cushion 44 x 21 in - Cast Shale

In this review the Sunbrella Outdoor High Back Chair Cushion in Cast Shale is assessed for anyone who wants to refresh outdoor wicker or Adirondack seating with a durable, comfortable pad. The bottom line: this cushion is best for homeowners who prioritize long-lasting, fade-resistant fabric and a thick, supportive fill that fits most high-back patio chairs. The reversible design and Sunbrella fabric make it an easy upgrade for porches and patios where color retention and low maintenance matter.

Key Features

• Sunbrella fabric: Provides fade-resistant, water-repellent performance so the cushion keeps its color and resists wear outdoors.
• Generous thickness: At approximately 3.5 in thick the pad delivers noticeable comfort and support for extended sitting.
• Universal fit: Sized at 21 in W x 44 in H to fit most high-back wicker, Adirondack, and rocking chairs without complex adjustments.
• Reversible design: Can be flipped for even wear and longer life, extending the time between replacements.
• Low maintenance: Spot clean with soap and water for simple care and to keep outdoor spaces guest-ready.
• Service agreements: Includes a 1-year limited service agreement for manufacturing defects plus a 5-year limited agreement on Sunbrella fabrics against color loss and strength issues.

Who It's For

This cushion suits homeowners who want a near-instant style and comfort upgrade for patio wicker, rocking chairs, or Adirondack seating and who value durable, fade-resistant fabric. It is ideal for covered porches, patios, and outdoor rooms where occasional wet exposure or strong sun can fade weaker materials.

Those who need ultra-soft foam for indoor lounge furniture or a custom-size cushion should look elsewhere; this product is built for standard high-back outdoor seats and emphasizes durability and easy care over plush indoor upholstery softness.
