*KeyFeatures *Dual-Sided Comfort: Our crib mattress offers double-sided comfort. One side provides stable support for infants (0-9 months), preventing the child's face from sinking into the mattress and reducing the risk of suffocation. The other side offers coolness and airflow for comfortable sleep for children over 9 months. *More Solid Support: Crafted with a high-density foam sponge, our toddler mattress maintains a firm yet comfortable surface to support proper sleeping posture and spine development. In addition, the high-density foam also provides good support for the child's spine, avoiding excessive spinal curvature or pressure during sleep. *Enhanced Breathability: Featuring gel memory foam, breathable materials, and other multi-layer structures, our baby crib mattress promotes air circulation, and prevents water drops buildup. Provide a drier, more comfortable sleeping environment. *Certified Safety: With OEKO-TEX, Certipur, and CPC certifications, 0 formaldehyde 0 glue, etc., this mini crib mattress meets stringent quality, durability, and safety standards, ensuring a healthy sleep environment for your child's growth. *Waterproof & Easy to Clean: The soft waterproof outer cover is made of 100% polyester without fiberglass and chemical smell. The TPU waterproof layer keeps the breathable crib mattress dry even if your child wets the bed. Just wipe the surface of the mattress with a damp cloth or paper towel to avoid frequent cleaning, saving time and effort. ******************************************************************************************************* *Specifications Item Model Number: F2301148 Thickness: 3 inches, double layer Material: Gel Memory Foam + Regular Foam Product Weight: 5.1 lbs / 2.3 kg 3 % Product Size: 24x38x3.1 inch/610x965x80 mm ******************************************************************************************************* *Pakcage Content 1 x Crib Mattress 1 x Instruction Manual 2 x Bed Covers
