A 3mm spacer promotes air circulation and breathability. The underside is a water-resistant quilted fabric.An anti-microbial treatment reduces the likelihood of allergic reactions to allergens caused by dust mites and pet hair. The breathable mesh topper is heat regulating, promoting airflow and dispersing heat while perspiration control allows moisture to dissipate through the fabric, ensuring babys sleep space is cool and dry.The zip-off mattress topper is machine washable and the waterproof layer protects from night-time nappy leaks.
