This are custom pillow forms or inserts made in the USA.
Poly Silk is a down alternative that is fluffy with a long life. It doesn't pack down like a standard cheap poly pillow will. I have poly silk bed pillows that I have used for over 3 years that still will not crush down.
I haven't tried to wash poly silk, like I do feather pillows. Not sure what washing will do to the fiber.
Because of the way they are filled, you do not need to order up 1 size to fill out your corners.
Cover is very nice, high thread count cotton.
This company will make custom sizes for you. Timing is around 1 week plus shipping time.
Shipping: I have figured out how to suck all the air out of the pillow so that I can ship them in flat Priority Rate boxes. Saves your large quantities on shipping!
