What is a Pillow Insert, and What is Inside the Pillow Insert?

If you wonder what a pillow insert precisely is, we will try to explain it in a few sentences so that it will become understandable to you.

A pillow insert is actually a fabric bag fulfilled with different kinds of materials that keep its fluffiness. In most cases, the pillow insert is filled with feathers, foam, down feathers, cotton, etc. The pillow insert is stuffed in a light fabric “bag” with a different shape and size, which goes into a pillowcase.

Pillow insert is the already sewed pillow you often buy from a home store. It is the sewed fabric filled with different kinds of stuffing materials. You can even make pillow inserts at home, depending on the purpose and size you need. 

Many pillow inserts are filled with down or feathers. Down and feathers are two different things that play a role in the pillow’s softness, volume, and weight. Also, in the past years, you might see a lot of pillow inserts filled with memory foam.


Down-stuffed pillows are pricier because dawn is a pretty pricy material. Down has higher quality than feathers because it offers more softness, making you feel like you lay on a cloud.

Then, the down-stuffed pillow has greater durability because the down gets back into the primary position much faster. And the third advantage of the down is its insulation. The down is the world’s most popular natural insulator.


Feathers are also commonly used stuffing for pillow inserts. The feathers are taken from different parts of the duck or goose’s body. The feathers contain quills, which might sometimes poke you if they turn in a different position.

The feather-stuffed pillows should be filled with a larger amount of feathers because they might collapse and make the pillow flatter. So, if you opt for a feather-stuffed pillow insert, ensure it has a good filling.

Feather-stuffed pillow inserts are much more affordable to buy and have better flexibility so that you can easily fold the pillow and adjust it around the neck.

Memory foam

Memory foam-stuffed pillow inserts might be a good option if you seek a sleeping pillow. These pillows might be filled with a single slab memory foam, layered memory foam, contoured memory foam, or shredded memory foam.

Memory foam has a lot of advantages, which is why many pillows are filled with memory foam nowadays.

The advantageous side of memory foam-filled pillow inserts offers better sleep with less neck and shoulder pain, might reduce snoring, might relieve pressure points, have better breathability, have better texture and contour that provide spine alignment, etc.
