numu air® Water-Repellent Crib Base Protector
Ultimate Protection, Zero Mess
Crafted to sit beneath the numu air® sleep surface, this protector collects spills, diaper leaks, and other fluids—shielding your crib base and floor while preserving a hygienic space.
Raised Edges for Maximum Coverage
Designed with elevated borders to contain liquids, keeping messes contained and simplifying cleanup—even during overnight leaks or spit-ups.
Easy to Clean & Maintain
Wipe clean or hand-wash with mild soap and water. Dries quickly and is ready for reuse almost immediately.
Reliable Detection
Since the net is very thin, with this adapter, a breathing or motion monitor can detect motion easier than with a regular thick mattress.

Preventing Spillage & Stains
The protector stops urine, vomit, and other potential contaminants from contacting the crib or the floor.

Hard Raised Edges
The edges stop the collected liquids from overflowing from the protector and make it easier to pick up.

Easy-Peezy Solution
When the ‘peezy’ happens, hold the crib base protector by the corners and take it to the bathroom for a cleanup. Easy!
Crib Base Protector Dimensions
The dimensions are 40" x 27.5". The size is smaller than the breathable mattress intentionally. This is important to allow free air circulation, while maintaining a proper level of protection against spillage and stains.
Cleanups Are Easy
In most cases, giving the protector a rinse in the shower will make it sufficiently clean and ready to be used again. If required, wash the oilcloth with mild soap. Machine washing is not recommended, as it might reduce the water-repelling capabilities of the fabric.
