Outdoor Bench Cushion 60 x 18 x 3.5 in Green - Waterproof Seat Pad

Our review of this 60 x 18 x 3.5 in green bench cushion finds it best suited to homeowners who need a durable, comfortable replacement seat for a porch swing or outdoor bench. The single biggest reason to buy is the combination of a full 3.5 in of high resilience foam and a waterproof double-layer polyester cover that holds up outdoors while offering noticeable comfort and support for long seating sessions.

Key Features

• Waterproof double-layer fabric: The coated 300GSM polyester keeps rain out so the foam stays dry and the cushion remains usable after light storms.
• 3.5 in high resilience foam: The 32D foam provides firm yet comfortable support that reduces pressure points during extended sitting.
• Fade resistant color: High-temperature dyeing helps preserve the green color under sun exposure and keeps the cushion looking newer longer.
• Non-slip and tie straps: Two adjustable straps on each side plus a non-slip bottom help the cushion stay put on benches and swings.
• Removable cover with YKK zipper: The zipper allows for easy removal and cleaning, though some users reported variable zipper durability.

Who It's For

This cushion is a good match for people who want a purpose-built outdoor seat pad for backyard benches, porch swings, or loveseats and who prioritize weather resistance and firm support. It is especially useful for those who sit for long periods and want a thicker, higher-density foam than standard thin pads.

Shoppers who need a custom fit should measure their furniture carefully before ordering, and those who expect a perfectly flat cushion immediately should be aware it may arrive vacuum-compressed and need up to 72 hours to fully expand. If zipper longevity is critical, consider inspecting returns policies since a few customers noted zipper issues.
