outdoor high back cushion

Common sizes range about 21–31.5 inches wide and 3–7 inches thick. Example dimensions from listings include 24" x 21" x 6", 21" x 28" x 3", 31.5" x 25.5" x 7", and 22" x 24" x 5".

Cover fabrics include olefin, polyester blends, cotton, suede and polyester. Fill materials include high-density foam, polyurethane foam, other general foams, polyester fiber, and overstuffed cotton/sponge in some listings.

High-back outdoor cushions often include water-resistant or waterproof coatings, UV/fade resistance, stain resistance, mildew resistance, or are described as all‑weather designs.

Most care notes recommend spot or wipe cleaning; removable covers can be cleaned with soap and water. To prolong life, store cushions indoors or cover them when not in use.

Examples include seat pieces sized about 21" x 44" x 3" with corresponding back pieces around 21" x 28" x 3"; one listing also shows a long cushion option at 72" x 21" x 3".

Common securing methods are ties or string ties, rope belts, and strap systems (including adjustable or click‑close straps) that hold cushions in place.

Common cover fabrics include 100% olefin, polyester blends (for example 93% polyester/7% cotton), 100% cotton, 100% suede and 100% polyester.
