Listings use a range of fabrics, including polyester blends (e.g., 98% polyester/2% spandex), 100% polyester, 100% acrylic, 100% microfiber, 420D Oxford, and canvas.
Typical deep-seat widths and depths are about 22–25 inches (examples: ~22x24, 24x24, 25x25). Common seat thickness is around 5 inches. Some covers list maximum widths of about 26 inches or offer larger "universal" dimensions (for example 38 x 35 x 29 in).
Common options include sewn seams, zippers, elastic bands under the seat, ties to secure cushions, and adjustable cords or straps to achieve a snug fit.
Typical protective features include fade resistance, water resistance, stain resistance, and mildew or mold resistance. Some fabrics are also described as UV-resistant or spill-resistant.
Care instructions vary by listing: many recommend spot-cleaning or wiping and then line-drying or laying flat to dry, while some covers or slipcovers are labeled machine washable for easier cleaning.
Many two-piece cushion sets include one seat cushion plus one back cushion (filled). Other listings sold as 2‑pack sets may include two cushion covers or a pair of cover and matching pillow covers. Check the product description to confirm whether fillings are included.
Common constructions include dacron-wrapped foam seat cores and plush polyfiber back fills (often made from post-consumer recycled plastic bottles). Fill blends may also appear, for example a 50% polyester fiber / 50% foam blend.
Many deep seat cushions shown are about 5 inches thick. Verify the specific product listing to confirm exact thickness and compatibility before purchasing.
