Types of cot mattressesFoam mattressesFoam mattresses tend to be the least expensive. The simplest versions are made from a single layer of supportive foam completely covered with a wipe-clean, waterproof PVC cover. Some foam mattresses have ventilation holes, but these aren't necessary. Generally easy to keep clean. Good value for money. Can provide good support and resistance to denting. Some parents may not like the idea of the basic PVC-covered mattress because of concerns about clamminess. Mattresses with ventilation holes (designed to help keep your baby cool) can be more effort to keep clean if your baby is a dribbler or is often sick, because residue can gather in the holes and mesh.
