24 x 24 Deep Seating Cushion Set - Sunbrella Canvas Spa

In this review the RSH DECOR 24 x 24 deep seating cushion set is evaluated for patio owners who want a durable, comfortable replacement cushion with a pillow back. The bottom line: this set is best for outdoor chairs that need a resilient, colorfast fabric and a firm, supportive seat. The biggest reason to buy is the Sunbrella performance fabric, which resists stains and UV fading while offering a near-custom fit for standard 24 x 24 in deep seating. It reads like a practical upgrade rather than a decorative splurge.

Key Features

• Premium fabric: Sunbrella's 100% solution-dyed acrylic construction offers long-lasting colorfastness and stain resistance for outdoor use.
• Clear size spec: The seat cushion measures 24 x 24 in and the pillow back is 24 x 20 in, making it straightforward to check fit before purchase.
• Comfortable fill: A 4 in poly foam seat provides firm support while the pillow back uses hypoallergenic hospitality-grade fiberfill for softer back support.
• Practical closure: The seat cushion has a zipper closure for easy removal, while the pillow back is sewn for a clean, tailored appearance.
• Low maintenance: Spot cleaning with mild soap and water is sufficient to keep fabric looking fresh, and the Sunbrella surface is simple to care for.
• Warranty and build: Sunbrella fabric includes a five-year limited warranty and the cushions are manufactured locally in Upstate South Carolina.

Who It's For

This cushion set is ideal for homeowners with standard deep seating patio chairs who prioritize durability and color retention over trend-driven patterns. It suits anyone looking for a firm, supportive seat with a plush pillow back and who wants the reassurance of Sunbrella's performance fabric and warranty.

It may not be the right choice for owners of curved seating where a square 24 x 24 in foam insert can fit poorly, or for buyers seeking ultra-plush, down-like fillings or highly decorative trim. Also, customers who require an exact color match should double-check samples, since color accuracy received mixed feedback.

Pros & Cons

Cons
