patio furniture cushion slipcovers

Most patio cushion slipcovers are polyester-based. Common materials listed include polyester blends (for example 95% polyester), stretch blends that combine polyester with spandex, and heavier outdoor fabrics like solution-dyed polyester (often used for UV- and fade-resistant covers).

Attachment methods vary by design. Many stretch slipcovers rely on elastic pockets or bands that tuck under the cushion, while other styles use sewn seams to hold shape or zippers for a more secure, tailored fit.

Stretch slipcovers are sized for common square cushions—listings show dimensions around 18×18 up to 21×21 inches. Product specs also give stretch seat width ranges, for example about 16–20 inches, to indicate how much the cover can expand.

Common closure types include elastic closures or sewn seams on stretch covers and zippers on some outdoor or fitted cushion covers.

Covers labeled for outdoor use and UV/fade resistance typically specify solution-dyed polyester and may note a PU coating or other water- and UV-resistant finishes to help resist sun damage and fading.

Listings show a range of pack sizes, including single covers, 2‑packs, 4‑packs, 12‑packs, and larger 30‑packs.

Weather-resistant features called out include solution-dyed polyester, PU coatings, fabrics described as water- or UV-resistant, and construction advertised as fade-resistant.

Dimensions mentioned across listings include stretch widths of about 16–20 inches, deep-seat examples around 22×24 to 25×25 inches, a stated maximum width of 26 inches, and a specific cushion size of 19×19×5 inches (thickness).

Stretch slipcovers are generally quick to install because elastic pockets or bands stretch over the cushion; some models also include zippers to make removal and replacement easier.
