I'm Jacob Katz, founder of Circadian. We make natural pillows and duvets by hand in a New Jersey workshop, with six adjustable fills so you can match the pillow to how you sleep and dial in the loft through the side zipper. The organic cotton and organic wool pillows carry full Global Organic Textile Standard (GOTS) certification on the fill and the cover, license GOTS-10229, searchable in the public GOTS database. Every order comes with a 60-night trial and free shipping both ways. See the pillows at circadianrest.com.
