Sizes vary widely. Common lengths are about 78–80 inches, widths generally range from roughly 19.7 to 26.4 inches, and thicknesses span about 1.2 inches up to 6 inches depending on style and fill. Always compare a product’s listed length × width × thickness to your chaise before buying.
Outdoor black chaise lounge cushions often include water-repellent or water-resistant fabrics and UV or UPF sun resistance to reduce fading. These treatments help protect against light moisture and sun exposure, but check the product description for specific performance claims.
Some cushions have sewn-in (fixed) covers, while others use zippers for removable covers. Removable covers make cleaning easier—check product details to confirm zipper placement and whether the cover is washable.
Compressed foam or sponge cushions typically need time to recover—most listings note about 24–48 hours for the foam or sponge to fully expand after unpacking.
Measure the seat length, seat width, and desired thickness (seat depth). Then compare those measurements to the product’s listed length × width × thickness to ensure a proper fit.
