IPYNBAP Outdoor Bench Cushion 48x18x5 in Dark Green — Waterproof, Memory+High-Density Foam

IPYNBAP Outdoor Bench Cushion is a 48" x 18" x 5" dark green seat pad built for outdoor and indoor benches, offering waterproof protection, resilient foam support, and a tailored tufted finish.

This bench cushion combines weather-ready materials with comfort-focused construction to refresh porch benches, window seats, swings, and dining benches. Its 300 GSM polyester cover includes a TPU inner layer for double-sided water resistance and fade control, while a mixed memory/high-density foam core preserves shape and cushioning through regular use. The dark green color adds a classic, low-maintenance look that complements outdoor settings and indoor nooks alike.

How does this cushion stand up to rain and sun exposure?

The cover is crafted from a high-density polyester treated for fade resistance, and there is an inner TPU waterproof layer that prevents moisture from saturating the foam. Because the fabric is double-layer waterproof (front and back), brief exposure to wet weather is less likely to damage the cushion or stain the furniture beneath.

• 300 GSM polyester outer fabric resists fading from sunlight.
• TPU waterproof membrane inside the cover for spill protection.
• Double-layer waterproof design reduces moisture transfer to furniture.
• Stain-resistant finish eases outdoor maintenance.

Will this seat pad stay comfortable and keep its shape over time?

The cushion core blends memory foam with high-density foam, giving a balance of contouring comfort and structural support. That combination reduces quick flattening and helps the cushion recover its profile after frequent sitting.

• Memory foam provides pressure-relieving comfort for longer sits.
• High-density foam maintains overall thickness and edge support.
• Tufted construction helps distribute filling and limit shifting.

What sizes and furniture types is this cushion suited for?

This listing includes one bench cushion sized 48" wide by 18" deep and 5" thick — measure your seating surface before ordering to ensure the best fit. Its dimensions and style make it appropriate for porch benches, patio swings, window seats, indoor benches, and some dining benches.

• Single cushion: 48" W x 18" D x 5" T.
• Fits outdoor benches, window seats, swings, and narrow sofas.
• Ideal for adding padding to hard wooden or metal seating.

How should I care for and unpack the cushion?

The cushion ships vacuum-sealed to save space; allow up to 24 hours for the filling to fully expand after opening. The water-resistant and stain-resistant cover requires minimal upkeep — spot clean as needed and avoid prolonged saturation or machine washing to protect the TPU layer.

• Arrives compressed in vacuum packaging—let it decompress for 24 hours.
• Spot clean stains with mild detergent and a damp cloth.
• Avoid machine washing or tumble drying to preserve waterproof lining.
