outdoor seat back cushion

Reported fill materials include 100% foam (listed generically as “100% Foam” and specifically 100% polyurethane foam), polyester fiber, high-density 28D foam, high-resilience cotton (described as overstuffed soft cotton), and sponge or premium sponge fillings.

Listings commonly note water-resistant or waterproof coatings, fade resistance/sun protection, and stain resistance to help cushions withstand sun exposure and moisture.

Many outdoor cushions have removable zippered covers for easy cleaning; some items use sewn seams instead and do not have removable covers.

Care varies by product: most list spot-cleaning or wiping clean, some recommend hand washing, and at least a few items are described as machine washable. To protect cushions, avoid leaving them in rain and store them until fully dry if they get wet.

Common attachment methods include rope belts and multiple string ties, adjustable straps, and click-close (buckle) straps to secure cushions and reduce slipping.

Seat cushions typically range from about 3" to 6" thick. Back cushions are often similar in thickness or slightly thicker, with reported back thicknesses up to about 7".

Available types include deep seat sets (seat plus back pillow), hinged chaise lounge cushions for loungers, high‑back chair cushions, and multi‑part or extended cushions designed for chaise-style or lounge chairs.

Many cushions are vacuum-compressed for shipping; once unpacked they typically need about 2 hours or more to regain shape. Gently warming with a hair dryer on low can help speed recovery.
