Cosatto Springi Supa 140 Cotbed Mattress Springi Supa is a supportive snoozystar with pocket-sprung power. His individually wrapped springs are individuals but all with one aim, to support little limbs. They’re an army of magic moulders moving separately to accommodate baby’s shape. This premium mattress makes life easy with easy-peel covers washable at 60°C, a removable adjustable waterproof liner, and breathable water-resistant fabric (just in case). Springi Supa’s got it covered. For added protection against over-exuberant boing, Springi Supa has a polypropylene liner to prevent poke-throughs – that’s Cosatto mattress magic. Springi Supa is one supremely sprung mattress for your little snoozy sprite.
