Sunbrella Deep Seating Cushion Set 23 x 24 Seat - Buttercup Yellow

In this review the Sunbrella deep seating cushion set in Canvas Buttercup Yellow is evaluated for outdoor chairs that need a balance of durability and comfort. The bottom line: this pair - a 24 x 23 in 4 in thick foam seat and a 24 x 20 in pillow back - is best for homeowners who want long-lasting, colorfast performance fabric and a firmer, supportive sit. The review focuses on fit, fabric performance, and everyday maintenance so readers can decide if this set suits their patio or covered porch seating.

Key Features

• Performance fabric: Sunbrella 100% solution-dyed acrylic offers stain resistance and UV protection so cushions stay colorfast outdoors.
• Clear size specs: The seat cushion measures 24 x 23 in and the pillow back is 24 x 20 in, making it straightforward to check fit before purchase.
• Comfortable fill: The seat uses a 4 in poly foam insert for a supportive, moderately firm feel while the pillow back is filled with hypoallergenic hospitality-grade fiberfill for softer support.
• Practical construction: A zipper-closed bottom cushion allows easier replacement of the foam insert, while the sewn-seam back keeps fiberfill secure.
• Low maintenance: Spot clean with mild soap and water and air dry to keep fabric integrity, with the recommendation to store or cover during bad weather.
• Local manufacture: RSH Decor produces these cushions in Upstate South Carolina, reflecting small-family business craftsmanship.

Who It's For

These cushions are ideal for homeowners with deep-seated outdoor chairs or replacement cushions who prioritize durable, fade-resistant fabric and a neat, tailored look. The set suits covered patios, porches, and areas where occasional wetting and sun exposure occur but not constant submersion.

People to avoid these cushions include those with curved seating where a rectangular 24 x 23 in foam block may not fit well, and buyers who want an ultra-soft, plush seat, since the 4 in poly foam has a firmer, structured feel. Also consider alternate sizes if your chair dimensions fall outside the stated measurements.

Pros & Cons

Pros

• High-quality Sunbrella fabric resists stains and fading, which preserves appearance over seasons.
• Clear measurements and zipper access make fit and future maintenance straightforward.
• Firm 4 in foam provides stable, supportive seating that many customers found comfortable and durable.
• Locally manufactured by a family-owned company, offering a sense of provenance.

Cons

• Color accuracy receives mixed feedback, so the Buttercup Yellow may not match every existing scheme exactly.
• The foam seat may not conform to curved seating, limiting compatibility with some chair styles.
