Summsun Outdoor Bench Cushion Pad 42x18x3 in Dark Grey — Weatherproof, High-Density Foam

The Summsun Outdoor Bench Cushion Pad is a 42 x 18 x 3 inch weatherproof, high-density foam seat pad designed to add durable comfort and fade-resistant style to garden benches, porch swings and patio seating.

Built from 250gsm polyester with anti-fade treatment and a 28D high-density sponge core, this Summsun cushion combines weather resistance, supportive comfort and easy maintenance. The dark grey finish offers a neutral, modern look that pairs with metal, wood or wicker outdoor furniture. It ships compressed and includes a removable machine-washable cover for simple care.

How does this cushion handle rain and sun exposure?

The outer fabric is a waterproof, 250gsm polyester treated for colorfastness so it resists water penetration and fading from sunlight. While designed for outdoor use, prolonged submersion or continuous exposure to heavy storms should be avoided to prolong life.

• Waterproof polyester face repels light rain and splashes.
• Anti-fade treatment keeps dark grey tone from bleaching in sun.
• Quick-dry foam and removable cover speed up drying after wetting.

Will the cushion provide real support for long seating periods?

The interior uses 28D high-density sponge that offers firm, resilient support and returns quickly to shape after use. It reduces pressure on hips and lower back better than thin or low-density pads, making it suitable for extended outdoor relaxation.

• 3-inch thickness balances cushioning with posture support.
• High rebound foam maintains shape through repeated sitting.
• Firm density helps prevent bottoming out on narrow benches.

What sizes and furniture types does this pad fit?

This single-piece cushion measures 42 x 18 inches and fits most standard garden benches, porch swings, outdoor loveseats, wooden and metal benches, and some picnic seating. Measure your bench to confirm a snug fit before ordering.

• Standard bench-friendly dimensions: 42" long by 18" deep, 3" thick.
• Suits metal, wood, wicker benches and porch swings with flat seats.
• Available colors include dark grey plus navy, beige, red, sage, teal, and black for matching décor.

How easy is it to clean and store this outdoor cushion?

The cover unzips and is machine washable, making routine cleaning straightforward. Cushions are shipped compressed; allow 1–3 days for full expansion and return to original thickness after unpacking.

• Removable zippered cover machine washable for simple care.
• Compressed packaging reduces shipping bulk; allow recovery time.
• Store in dry shade or a breathable storage bag for off-season protection.
