Premium Soft Cotton Terry with TPU Back Coating: The Trance Home Linen Crib Bed Protector features a top surface made of premium Soft Cotton Terry with a TPU (Thermoplastic Polyurethane) back coating. This combination not only extends the life of your baby mattress but also ensures that the protector is waterproof. The use of Soft Cotton Terry maintains the natural feel of the mattress, offering comfort to your baby, while the TPU back coating effectively repels liquids. | TPU Certification for Product Quality: The product is TPU certified, assuring customers of its high quality. This certification guarantees that the crib protectors are free from harmful substances such as PVC, vinyl, phthalates, fire retardants, and other toxic chemicals. This commitment to safety ensures a healthy sleep environment for both you and your baby. The relevant certification documentation has been uploaded to provide authoritative proof of the product's quality and safety standards. | Airflow Technology for Breathability: The crib protectors employ advanced airflow technology, creating a 100% waterproof barrier that still allows air to circulate through the protector. This feature not only keeps your baby comfortable but also protects the mattress from allergens, dust mites, bacteria, perspiration, urine, and other fluids. The breathable design is especially beneficial when putting infants to bed, offering a hygienic and comfortable sleeping environment. | Versatile Fit and Easy Maintenance: The package includes two crib protectors designed to fit mattresses of size 24x48 inches, with a thickness of up to 4 inches. This versatile sizing ensures a snug fit for most standard crib and baby mattresses. Additionally, the crib protectors are easy to maintain, being machine washable. For best results, use a mild detergent and opt for a cold wash. During drying, keeping the terry side up helps maintain the quality and functionality of the protector. | Hypoallergenic and Family-Friendly: The Trance Home Linen Crib Bed Protectors are hypoallergenic, making them an ideal choice for families concerned about allergies. The absence of harmful chemicals coupled with the breathable design contributes to a healthier sleep environment. These protectors are especially useful for parents dealing with bed wetting during infancy.
