This Outlast® Deluxe Pocket Sprung Cot Bed Mattress offers a high level of support for your baby due to the supportive pocket springs, as well as being a luxuriously comfortable place for your baby to sleep. It is tested to BS1877 pt. 10, meeting all UK regulations & UK fire safety standards, for a safer sleep. Pocket sprung mattresses are perfect for offering a supreme level of support due to the independent support that each spring offers. Supporting your baby's weight & movements, pocket springs will ensure your baby is sleeping in the correct position, keeping their spine aligned for a healthy sleep. Outlast® fabric is designed to balance your baby's body temperature & prevent overheating during the night. It works by drawing out & storing heat energy, & then releasing it when the body begins to cool. Your baby will be much less likely to wake from overheating when using an Outlast® cover. Manufactured in the UK with quality raw materials & detailed finishing, you can purchase your baby's cot bed mattress from one of the UK's leading mattress retailers with the confidence of a 2 year manufacturer's warranty.
