To create this extra soft crib sheet, we worked with Cotton Sateen —a weave that has a softer, silkier feel compared to cotton sheets. Lofty, breathable and keeps the baby comfortable through the night. It's also OEKO-TEX certified, which means it’s woven from only the purest materials and free of harmful toxins. Pairs with Bows & Butterfly Collection. Crafted in Portugal with European quality and craftsmanship. Uses the superior softness of sateen-weave cotton. 430 TC. Packaged in its very own tote bag—because practicality means everything. [SPECS] DIMENSIONS Dimensions: 27.5" W x 52" L x 10"D. Can fit a Toddler Mattress.
