Speak with our Sleep ConciergeWhat does 15 denier mean?
Denier refers to the thickness of the individual fibers used in the filling. The 15 denier polyester used in this insert is designed to provide a soft, lightweight feel while helping create the fullness you want from a decorative pillow insert.
What is knife-edge construction?
Knife-edge construction means the pillow has a clean, defined edge rather than a rounded or piped border. It gives the insert a simple, polished shape and makes it easy to pair with a wide variety of decorative pillow covers.
Will it make my pillow cover look full?
That's exactly what a good pillow insert is there to help with! The polyester down alternative filling provides loft and softness, helping your decorative cover take on a fuller, more finished appearance instead of looking flat or empty.
Is it easy to put inside a pillow cover?
Yes! The insert is designed to be used inside a decorative pillow cover. Depending on the size and fit of your cover, you can gently work the insert into the corners and adjust the filling until the pillow has the shape and fullness you like.
Is this a good option if I don't want natural down?
Yes! Since the filling is polyester down alternative, this insert is a great choice for customers who prefer a synthetic filling instead of natural down or feathers. You still get a soft, plush decorative pillow without a down-filled interior.
Why should I choose the Polyester Pillow Insert Case?
If you're looking for a soft, versatile insert that can help your decorative pillow covers look full and inviting, this is a great option. With a 100% cotton cover, polyester down alternative filling, 15 denier fibers, and clean knife-edge construction, it combines comfort and a polished appearance in a simple design. And because it's processed and filled in the USA, it's an easy, dependable addition to your home décor collection.
