caring for your baby's mattress

Regularly cleaning your baby's mattress is vital to ensure that they enjoy a clean and hygienic sleep, it also means that the mattress will last longer.

Keeping your cot's mattress clean is easy:


  • if it has a fabric cover simply wash it with a non-biological mild detergent
  • if the mattress has a PVC cover, clean it regularly with a mild solution of warm water and disinfectant or sterilising solution, or use an antibacterial spray
  • mattresses with non-removable covers should be vacuumed or sponge cleaned
  • depending on mattress type, turn regularly to maintain shape and/or rotate it head to foot so both ends are used equally
  • remember that you should never put your baby on a mattress that hasn't fully dried, and don't dry-clean the mattress as this can leave chemicals that could be harmful to your infant
