They are highly compressible, allowing for a soft and fluffy appearance, which makes them ideal for decorative purposes, but may require frequent fluffing to maintain shape.

They provide a similar plush look and feel but often come with less maintenance and are generally more affordable, making them a popular choice for those with allergies.

They maintain their shape well and provide a more structured look in king shams, although they may not have the same plush appearance as down or down alternative options.
