Mamma-pillo is committed to environmental sustainability. Following exhaustive research in early 2017 we have re-designed the Mamma-pillo to create the Mamma-pillo “ECO Multipurpose Support Pillow”. The new and enhanced Mamma-pillo now contains recycled PET Fibre Fill and the Organic range contains Corn Fibre Fill sourced from within Australia https://www.innergreen.com.au/eco/ . Either 100% Cotton or 100% GOTS Certified Organic Cotton (Organic range) is now used for the inner pillow cases and twin pillow casing. The outer covers are made of 100% Cotton, 100% GOTS Certified Organic Cotton or OEKO-TEX Standard 100 Certified Cotton (Organic Range). All seams are now sewn using cotton thread or GOTS Certified cotton thread (Organic Range).
