It’s 100 polyester which I did want. The description never mentioned polyester. Disappointed in not listing polyester in the description of the product. It said cotton

Very nice quality insert. The fabric on the outside is so soft and could almost be used by itself

These feel like down and are really high quality. Only complaint is that the listing said "(set of 2)" so I ordered 2 sets (for a total of 4) but it didn't show up that way on the order confirmation so I was only sent two pillows, not 2 sets of 2. When I reached out to Wayfair they made it right and sent me 2 more because I was able to show them what the item page says, but it was a little annoying to have to do it, and to wonder whether or not I'd be able to prove I paid for 2 sets of 2.

Thank you, I wasn’t expecting anything. These will come in handy storing extra pillows instead of just throwing them in the closet!

Perfect down alternative pillow inserts
