Summsun Outdoor Bench Cushion Pad 59x18x3 in Black — Waterproof 28D High-Density Foam

Summsun Outdoor Bench Cushion Pad is a 59 x 18 x 3-inch waterproof, high-density foam seat pad designed to add durable comfort to garden benches, porch swings, and other outdoor seating.

Built for outdoor life, this bench cushion pairs a 250gsm weather-resistant polyester cover with 28D high-density foam to give a firm, supportive sit that rebounds after use. The cover resists fading and moisture, and the zip-off design makes machine washing simple. It ships compressed and recovers its shape within a few days, so it’s ready to refresh patio furniture without fuss.

How comfortable and supportive is this cushion for long sitting sessions?

The Summsun bench cushion uses 28D high-density sponge that balances firmness and comfort, reducing pressure points while maintaining shape. High rebound properties mean it won’t quickly flatten, delivering consistent support over time.

• 3-inch thickness for noticeable padding without bulk
• 28D high-density foam provides stable support and resilience
• Designed to ease hip and lower-back pressure for longer sits

Will the black fabric stand up to rain and sun on a covered patio?

The outer material is a 250gsm polyester treated for water resistance and anti-fading performance, so it holds up to light rain and prolonged sun exposure better than untreated fabric. For heavy storms or extended wet weather, storing the cushion indoors will extend its life.

• 250gsm polyester resists moisture and dries quickly
• Colorfast treatment reduces fading from sunlight
• Quick-dry construction limits mildew risk when kept ventilated

How easy is it to clean and maintain this outdoor bench pad?

The cover unzips for machine washing, making spot stains and seasonal cleaning straightforward. Because the cushion ships compressed, allow 1–3 days for it to fully expand before first use to reach intended comfort and loft.

• Removable, machine-washable cover for simple cleaning
• Compressed packaging—recovers shape within 1–3 days
• Routine airing prevents moisture buildup and keeps freshness

What benches and outdoor pieces does this cushion fit best?

The 59 x 18-inch footprint and 3-inch depth suit many common bench types including garden benches, porch swings, wooden and metal benches, and some outdoor loveseats. Always measure your seating before purchase to confirm fit.

• Fits standard garden benches and porch swings (measure first)
• Works with metal, wood, and composite outdoor seating
• Available in multiple neutral colors to match outdoor decor

Who is this for? The Summsun Outdoor Bench Cushion Pad is made for homeowners and renters who want a tidy, durable upgrade to outdoor seating without custom upholstery. It’s ideal for people who need weather-resistant materials, straightforward cleaning, and firm yet comfortable support on benches, swings, or patio furniture. Choose this cushion if you want a practical black bench pad that recovers from compression, resists fading, and keeps outdoor seating inviting season after season.
