Summsun Outdoor Bench Cushion Pad 42 x 18 x 3 in Navy Blue — Weather‑Resistant, High‑Density Support

Summsun 42 x 18 x 3-inch navy outdoor bench cushion pad is a weather-resistant, high-density foam seat pad designed to add durable comfort and colorfast style to garden benches, porch swings, and picnic seating.

This 3-inch-thick cushion pairs a 250gsm polyester cover with 28D high-density sponge to deliver supportive seating that holds shape and resists fading. It ships compressed for convenience and quickly recovers its profile once unpacked. Available in neutral tones including navy blue, the pad fits many common bench and swing dimensions and includes a removable, machine-washable cover for straightforward upkeep.

Will this bench cushion fit my outdoor bench or porch swing?

The Summsun pad measures 42 inches long, 18 inches wide, and 3 inches thick, a size that matches most standard benches and many porch swings. We recommend measuring your seating surface to confirm compatibility before purchase, especially for benches with armrests or curved seats.

• Dimensions: 42 x 18 x 3 inches — standard rectangular bench cushion size.
• Fits: garden benches, front porch swings, picnic benches, metal and wooden seating.
• Tip: measure seat depth and length for snug fit on non-standard frames.

How does the cushion hold up to outdoor weather and sun exposure?

The outer shell is made from 250gsm polyester treated for water resistance and colorfastness, helping the cushion shrug off light rain and resist fading from sunlight. While weatherproof, the pad is not intended to be continuously exposed to heavy downpours—storing it under cover or indoors prolongs life.

• Material: 250gsm polyester fabric with anti-fade treatment for UV resistance.
• Water behavior: water-resistant exterior; best to keep sheltered in severe weather.
• Maintenance: removable cover cleans easily to maintain appearance.

What kind of comfort and support does the cushion provide?

Inside the cover is 28D high-density foam engineered for firm support and good rebound. The thickness and density work together to reduce pressure points, making long outdoor sitting more comfortable while retaining shape over repeated use.

• Filling: 28D high-density sponge for supportive, long-lasting seating.
• Thickness: 3-inch profile balances softness with structural support.
• Durability: high rebound foam that resists sagging with normal outdoor use.

How do I care for the cushion and what should I expect on delivery?

The cushion is compressed for shipping to reduce package size; allow 1–3 days after unpacking for the foam to fully expand and regain shape. The cover zips off for machine washing, making routine cleaning simple and efficient.

• Delivery: arrives compressed—fully expands within 1–3 days after unpacking.
• Cleaning: removable, machine-washable cover for easy maintenance.
• Storage: recommend sheltered storage during heavy rain or winter months.

Who this cushion is for: homeowners and renters who want a practical, comfortable upgrade for outdoor seating—ideal for people who host on patios, decorate porches, or use garden benches and swings regularly. It’s well suited for buyers who prioritize supportive foam, easy care, and weather-resistant fabric in a navy-blue option that blends with many outdoor palettes. If you need a larger, smaller, or waterproof-rated marine cushion, consider measuring your seat and checking product specifications for alternative models.
