Common zipper features called out in listings include extra-long zippers for easier removal, heavy-gauge rust‑proof nylon zippers for durability, and hidden zippers for a seamless appearance.
Listings say covers fully encase the pillow to shield it from dirt, dust, and daily wear—helping maintain freshness and extend the pillow’s usable life.
Typical dimensions listed are lengths of about 54–61 inches, widths of about 28–38 inches, and some listings also show an approximate 8‑inch depth.
Closures include envelope‑style back closures and zipper closures; some listings highlight hidden zippers or extra‑long zippers for easier use and a cleaner look.
Some listings explicitly label covers as “Hypoallergenic,” and several show certifications such as OEKO‑TEX STANDARD 100; one listing also mentions the Responsible Down Standard.
Many listings state the cover is sold unfilled. Look for phrases like “Pillow insert not included,” “Pillow covers only,” or “filling NOT included” to confirm the insert is not provided.
