When crafting our GOTS certified organic 100% cotton fitted sheets, we have considered everything: from our cotton's field of origin to your tiny one's unique nursery. Our fitted cot sheets have extra deep corners allowing for a snug fit and their strong double-sided premium jersey is soft and thick so that it's kind on your baby's skin. They are machine washable for easy care and last beautifully wash after wash. Our Tiny Difference - We use responsibly sourced certified organic cotton yarn that is knitted and dyed in England before being specially crafted into our velvety soft fitted sheets.
