The Coir & 100% Wool Crib mattress features a smart dual-core, breathable design made from high-quality natural materials, including 100% sheeps wool and coconut coir. The wool is carefully chosen for its thermoregulating properties, helping to keep your baby comfortable throughout the seasons, particularly as newborns cannot regulate their body temperature effectively until around 3 to 4 months of age. Two layers of soft sheeps wool provide gentle cushioning, while the core of premium coconut coir delivers firm, supportive comfort. Made from shredded coconut fibres, the coir creates a dense yet springy structure, offering a safe, firm sleep surface recommended for infants. Naturally hypoallergenic and resistant to dust mites without the use of chemicals, this mattress promotes a clean and healthy sleep. The removable cover can be unzipped for easy machine washing and line drying, making it practical for everyday use. Designed to fit snugly within the Maxi Cosi Iora Air crib, it offers a secure and supportive fit. We recommend measuring your original mattress before ordering, as dimensions may vary slightly.
