Summsun Outdoor Bench Cushion 48 x 18 x 3 in Black — Waterproof 28D High-Density Foam, Removable Washable Cover

Summsun Outdoor Bench Cushion Pad is a 48 x 18 x 3-inch waterproof, colorfast seat cushion designed to add durable comfort to garden benches, porch swings, and outdoor seating.

This Summsun bench cushion combines a weather-resistant 250gsm polyester cover with high-density 28D foam to give outdoor seats a supportive, resilient layer that resists fading and sheds rain. It ships compressed for compact delivery, and the removable, machine-washable cover makes upkeep effortless. Available in several neutral and bold colors, the 3-inch thickness balances softness with firm support for everyday outdoor use.

How does this cushion stand up to sun, rain, and regular outdoor use?

The cushion cover is made from 250gsm polyester treated to be waterproof and colorfast, so it sheds light rain and resists UV fading. The construction is intended for outdoor exposure while retaining color and texture longer than untreated fabrics.

• 250gsm polyester fabric with weatherproof treatment
• Anti-fading technology for extended UV resistance
• Waterproof surface that helps keep the inner foam dry

Will the padding provide enough support for long sitting periods?

Summsun uses 28D high-density sponge that offers a balance of firmness and cushioning to reduce pressure on hips and lower back during longer sits. The foam's rebound properties help the cushion retain shape and support through repeated use.

• 3-inch thickness for visible comfort without bottoming out
• 28D high-density foam for stable, long-lasting support
• Designed to minimize sagging and restore shape after use

Is the cushion easy to fit, clean, and store?

The pad measures 48 x 18 inches and is suitable for most benches and small loveseats; always measure your furniture before ordering to ensure proper fit. It arrives compressed and should recover its full thickness in 1–3 days; the cover zips off for machine washing to simplify maintenance.

• One-piece cushion sized 48 x 18 x 3 inches for common bench dimensions
• Compressed shipping—allow 1–3 days to fully expand
• Removable, machine-washable cover for easy care
