Summsun's 48 x 18 x 3-inch outdoor bench cushion pad in navy blue is a weatherproof, high-density foam seat cushion designed to add durable comfort and color-fast style to benches, swings, and patio seating.

Whether you're refreshing a garden bench or upgrading porch seating, this Summsun cushion combines a thick 3-inch high-rebound foam core with a rugged 250gsm polyester cover to resist moisture and fading. It ships compressed for safe delivery and includes a removable, machine-washable cover for hassle-free cleaning. The 48 x 18 inch size fits many standard benches and outdoor furniture pieces, and the navy finish pairs easily with neutral and bright outdoor palettes.

How does this cushion hold up to weather and sun exposure?

The cover is woven from 250gsm polyester treated for water resistance and colorfastness, so brief exposure to rain and regular sunlight won't quickly degrade the fabric or hue. The materials are selected to shed moisture and slow fading, extending usable life compared with untreated indoor fabrics.

• 250gsm polyester shell engineered for water resistance
• Anti-fade treatment to retain navy color under sunlight
• Quick-dry foam core that resists moisture buildup

Will the cushion be comfortable for long sitting and different body types?

Inside the cover is 28D high-density sponge foam that provides firm support with responsive rebound, distributing weight to reduce pressure during longer sits. The 3-inch thickness offers a balance of plushness and structural support suitable for everyday outdoor seating needs.

• 28D high-density foam for even support and durability
• 3-inch thickness for comfortable yet supportive seating
• High-rebound properties to maintain shape over time

What furniture does this 48 x 18 cushion fit and how do I install it?

The 48 x 18 inch dimensions suit many garden benches, porch swings, picnic benches, and patio seats—measure your furniture first to confirm fit. Installation is straightforward: unbox the compressed cushion, allow it to expand for 1–3 days, then place it on the seat; the removable cover makes positioning and cleaning easy.

• Ideal for benches, porch swings, wooden and metal seating
• Ships compressed; allow 1–3 days to fully expand
• Removable, machine-washable cover for maintenance

How do I care for the cushion to keep it looking fresh?

Regular spot-cleaning and periodic machine washing of the removable cover will keep the cushion looking new; always follow care instructions on the label. Storing the cushion under cover or indoors during extended wet seasons will further protect fabric and foam.

• Removable cover is machine washable for easy cleaning
• Spot-clean as needed and air-dry thoroughly before reuse
• Store indoors or under shelter during long wet or winter months
