The covers have a sheen that looks a little like taffeta but--who are we kidding--it's polyester! I bought them to soften up (both visually and physically) a very stiff sofa bench in a homeschool but unfortunately they're not really soft and squishy so when you lean back on them, especially if you're a 40 lb kid, they don't have much give. They prop up nicely so they look good at the end of the day, and probably won't stain or disintegrate for 100 years! I though the price was a good value so overall I'm fairly happy.

Very nice pillows and the kids really like them.

My kids LOVE these pillows. My job and I just created a reading corner and these pillows were the perfect touch. They look forward to them everyday!
