When selecting a cot bed mattress, consider firmness and support. A firm and flat surface is recommended to reduce the risk of Sudden Infant Death Syndrome (SIDS). Materials such as foam, sprung, and natural fibres are commonly used. Foam mattresses are lightweight and affordable, while sprung options offer excellent support and durability. Natural fibre mattresses, made from materials like coconut coir and wool, are breathable and hypoallergenic.

Safety is paramount, so ensure the mattress meets British safety standards, such as BS EN 16890. The mattress should fit snugly in the cot bed, with no gaps around the edges to prevent entrapment.

Look for features like removable, washable covers to maintain hygiene, as babies are prone to spills and accidents. Waterproof layers can also be beneficial.

Overall, choosing the right cot bed mattress ensures a safe, comfortable sleep environment, supporting your child’s health and well-being from infancy through toddlerhood.
