These inserts are just ok. They are the correct size but they are pretty flat, if you want a nice plump looking pillow, you will need to size up or find a different insert that is fuller and has more fill to it. For visual comparison...the floral pillow has this insert in it, while the solid colored orange pillow has the down insert in it that I am trying to replace.

The inserts are well-designed and generously sized, providing ample coverage without being overly stuffed. They are comfortable and suitable for use on couches or beds. The ease of insertion and the fact that they come in sets of two make them an ideal choice for my needs. I have included a photograph to illustrate their appearance on my bed with two covers.

This is a nice set of pillow insets only. I ordered the 18" set. They are well made but not overly stuffed. I was a little disappointed at the thickness. I was hoping for more filler as pillows get packed down over time with use.

These 18 inch square Olefin pillow inserts with polyester filling by Creative Co-Op are very nice and well made. They are shipped flat wrapped but once open they expand. Not a heavy weight but this makes for a great filling for my decorative throw pillow sleeves.

These are nice large pillow inserts but are much flatter than expected. I was able to fluff them up a little but not as much as I would like. I got the 20 inch and they were easy to put into my pillow covers.
