19.5 x 20 x 5 in Rounded Back Seat Cushion - Deep Sunbrella Comfort

Our review of the 19.5 x 20 x 5 in Rounded Back Seat Cushion finds it best for homeowners who want a durable, weather-ready cushion that looks custom and feels substantial. The single biggest reason to buy is the combination of a 5 in CumuPlus fill with fade-resistant Sunbrella fabric, which delivers noticeable deep seating comfort and long-lasting outdoor performance without the plasticky feel of cheap cushions.

Key Features

• Sunbrella performance fabric: Maintains vibrant color and resists fading so the cushion stays looking fresh on patios and porches.
• 5 in CumuPlus fill: Provides plush, deep seating support that recovers well after use and suits lounge chairs and rockers.
• Rounded back design: Curved back and box edge styling give a tailored fit for chairs about 19 in to 21 in wide and 20 in to 22 in deep.
• Hidden zipper: A discreet closure preserves the clean look while allowing the cover to be removed for care or replacement.
• Indoor and outdoor use: Built for versatility so it works equally well in sunrooms, porches, and outdoor furniture setups.
• Proudly made in the USA: Manufactured with consistent craftsmanship since 2004 for reliable build quality.

Who It's For

This cushion is ideal for anyone furnishing a patio, porch, or sunroom who wants a tailored look and deep seating comfort from a single cushion. Its Sunbrella fabric and sturdy fill make it a practical choice for frequent outdoor use and for households that need a cushion which resists fading, stains, and general weather exposure.

Those who prefer a very soft, plush sink-in feel may want a softer fill; a few customers find the firmness toward the firmer side. Also check dimensions carefully for shallow seats, since the 5 in thickness is made for deep chairs roughly 20 in across.

Pros & Cons
