We highly recommend the numu® water-repellent crib base protector because the numu® air™ mattress, with its superior fluid permeability, allows liquids and spit-ups to pass through down to the crib’s base or, in tiered beds, potentially onto the floor, creating messes and stains.

To address this, we designed the numu® base protector, which is placed underneath the mattress, efficiently and simply collecting any fluids. Unlike common protectors in the market, our base protector is made from a dense fabric with a specially thick barrier that prevents any liquid from leaking out. Cleaning the protector is a breeze; just gather its edges and take it to the bathroom for a wash, ensuring nothing spills out.
