The essential first layer — 100% cotton on top, waterproof underneath, elasticated all the way around so it stays put no matter what.

• Protects the mattress completely — the built-in waterproof layer sits beneath the cotton surface; if the sheet becomes wet the mattress underneath stays dry; machine-washable at 30°C for a quick turnaround
• 100% cotton top surface — natural, breathable, and gentle against skin; the surface in contact with the baby is always cotton, never plastic or synthetic waterproof material
• Elasticated all the way around — stays firmly in position on the mattress even when the baby rolls, kicks, and moves during sleep; does not ride up at the corners
• Goes directly on the mattress as layer one — the YappyLux satin fitted sheet goes on top as the sleeping surface; you need at least two YappyShield sheets in rotation from day one
