Common sizes are square formats such as 18×18 inches and 20×20 inches. Some listings also offer oversized or specialty shapes—for example, a 20×24-inch heart pillow.
Closures include standard zippers, hidden zippers for a seamless look, and sewn-closed seams (common on reversible or permanently sewn styles).
Some listings are covers sold without fill. Finished velvet pillows typically use synthetic fills—down‑alternative or polyester inserts. Product details in listings may list fills with terms such as “80% Down Alternative,” “80% Polyester,” “100% Polyester,” “100% polyester alternative down,” or simply “soft polyester insert.”
Common decorative details are printed designs (marine or seasonal motifs), embroidered accents (often for holiday pillows), ruffles, and reversible constructions such as velvet on one side and faux shearling on the other.
Most listings show square shapes (for example, 18×18 or 20×20). Some items use specialty shapes as well, such as heart-shaped pillows.
