outdoor patio cushion covers

Common materials include polyester blends (examples: 80% polyester and 98% polyester), knit blends with spandex (e.g., 98% polyester/2% spandex), 100% microfiber, and heavier coated fabrics such as 600 Denier solution-dyed polyester or 420D Oxford with a double-layer coating.

Available sizes cover small to large cushions: stretch seat widths commonly fit about 16"–20", standard square cushions around 18x18" up to 21x21", deep-seat covers list sizes like 22x24" up to 25x25" (some state a maximum width near 26"), and some larger chair covers list maximum seat widths around 35" or specific dimensions such as 28" square or 38 x 35 x 29".

Common retention methods include under-seat elastic bands or elastic hem cords with adjustable toggles, sewn seams or easy-close fasteners, and zippers to secure the cover.

Listings cite UV- or fade-resistance for sun protection, water resistance or water-resistant coatings to guard against rain and spills, and heavier coated fabrics (for example, PU coating or double-layer coatings) for increased weather durability.

Care varies by material: many stretch-knit covers are machine washable; others recommend spot cleaning or wiping and then line drying or laying flat to dry; some advise hand washing. A few listings do not provide washing instructions.

Heavier-duty options called out by listings include 600 Denier solution-dyed polyester with a PU coating and 420D Oxford fabric with a double-layer coating; these are described as durable, water-resistant, and UV-proof for tougher outdoor conditions.

Many listings emphasize easy installation and removal: stretch-knit covers slip on quickly with an elastic fit and are machine-washable for convenience, while other covers use resilient zippers or easy-close fasteners for effortless on/off.

Standard stretch seat covers are sized for typical square or dining cushions (examples: around 18x18" to 21x21" or stretch widths like 16"–20"). Deep-seat stretch covers are sized larger (examples: around 22x24" up to 25x25" or maximum widths near 26") and some deep-seat packs also include pillow covers.
