A perforated fitted sheet is essential because it allows the air to circulate freely and the breathable 3D structure to work properly. We tested this function extensively in both dry and humid conditions. A conventional cotton sheet significantly reduces breathability. And when cotton fabric gets wet, the fibres hold in the moisture and prevent any air at all from passing through.
Not only is the AeroSleep fitted sheet perforated, it is also made of polyester, a fabric that doesn't retain moisture. Instead, it allows moisture to pass straight through into the mattress protector's absorbent layer so that your child can always breathe safely and stay dry.
Machine-washable at 60° for optimum hygiene, the fitted sheet dries quickly and is super easy to put on the mattress. It's a must-have!
