Cleaning Instructions

Cleaning the numu® air™ is straightforward, ensuring you can spend more time with your little one and less time on upkeep. Follow these simple steps for a fresh, clean sleeping environment:

Frame and Net Washing:

You can shower the entire mattress, including the frame, without disassembly. If you use soap, choose a mild one to protect the materials and your baby’s skin. The frame and net are made with rust-proof materials, so there’s no worry about water damage.


The unique net design allows for rapid air drying. For faster drying, gently wipe the frame with a clean, dry towel. Placing the mattress in a well-ventilated area or outdoors (in suitable weather) will expedite the drying process. The net will be ready for your baby again in no time.

Machine Washing:

The Comfort Layer and the bedsheets can be washed on a gentle cycle, at up to 104°F (40° C), and with mild detergent. Avoid bleach to preserve the fabric’s softness and color.

Maintenance Checks

To ensure your numu® air™ continues to provide the best support and safety for your baby, we recommend:

Monthly Inspections:

Regularly inspect the mattress for any signs of wear or sagging. As babies grow, adjustments might be necessary to maintain the perfect tension.


If you notice the sleep surface becoming looser or sagging, refer to the user manual (page 18) for instructions on adjusting the middle bar. This will help keep the surface taut and comfortable.


If you’re encountering any issues, check our user manual (page 22) that offers comprehensive solutions for common problems. For anything not covered, contact our dedicated Customer Support. It will assist with any queries or concerns you might have.
