Each range has its own sheet and protector, so choose the ones made for your cot's mattress. Register your mattress with your cot within 3 months of purchase on the Gaia Baby warranty registration page and keep your proof of purchase.

Safe sleep

Use only one mattress in the cot. Always place your baby on their back to sleep on a firm, flat surface. Do not put objects or accessories in your baby's sleep space, and never place the cot near a blind, cord, strap or similar item that could wrap around a baby's neck.
