What fabric is the breast feeding pillow made of?

Hi Elizabeth, The breastfeeding pillow is made of a 100% Polyurethane recyclable foam and covered by a removable, machine-washable cover. Only the organic cover for the Original and Deluxe and the Designer Super Deluxe cover for the Super Deluxe model are 100% cotton. All the rest of the covers for all models are now 100% baby-soft polyester. The material content of the inflatable pillow is 100% PVC tape, latex-free. Hope that helps
