Avoid the guesswork

These pillow inserts avoid the guess work of which size to buy. Work beautifully.

Comfortable and they keep their shape

My favorite pillow inserts. They are true to size and keep their shape. Not too hard, not too soft.

I received some beautiful Pentik pillow covers as a gift from Finland. These pillow inserts are perfect to put inside them.

Love that it is made in the USA !

This is a nice , firm insert. I love that it is made in the USA ! Sometimes inserts have an odor to them , but this one did not have any smell at all. :) I bought it to fill the Pentik Luumu pillow cover. It was quite difficult to make it fit and to fill the pillow out , but once I did , it looks great. It is very firm inside that particular pillow cover.

Not cozy

I don't really like this pillow - it's a little too hard to be cozy. But it is a good price.

pillow insert

Quality of this pillow insert is very low. Feels like something you would get for free on an airplane. I purchased and returned 4 and because of the size of the box, the return shipping was $40!

A perfect fit!
September 3, 2019
Yes. It fits the pillow cover for which it was purchased. More than that, I'm not allergic to it and the density - neither too soft or too hard - is perfect. Can't imagine what else one would want in a pillow insert. Nice to purchase at the same time to insure of a perfect fit.

Marimekko pillow
April 15, 2019
I purchased this pillow insert with the Marimekko Varvunraita pillow cover. The cover is lovely in shades of green and is of a nice heavy fabric. It looks amazing on my easy chair and is very comfortable. Shipping was also super fast. Thank you!

Perfect fit!

The pillow insert perfectly fit the Pentik pillows I purchased on the FinnStyle website.
They easily slipped into the pillow covers and have a nice amount of filling.

I'd debated ordering them on-line, thinking I'd buy them elsewhere, but am happy I ordered them with the pillows. They all came together in one (well-stuffed) box, but the inserts didn't stay compressed, and completely filled the pillows.

Excellent service and delivery (as usual) by Finn Style.
  • High quality pillow insert/fits perfectly.
  • I liked it much better when inserts were sold/part of pillow purchase.
