6. Operating Instructions
6.1. Mattress Height Adjustment
The crib features a 3-position mattress height adjustment. This allows you to lower the mattress as your baby grows and becomes more mobile, ensuring their safety.
- Highest Position: For newborns and infants who cannot push up on their hands and knees.
- Middle Position: For babies who can push up on their hands and knees.
- Lowest Position: For babies who can sit up or stand.
To adjust the mattress height, carefully remove the mattress and mattress support. Reattach the mattress support to the desired height using the appropriate hardware and attachment points on the crib end panels. Ensure all fasteners are securely tightened before placing the mattress back into the crib.
7. Maintenance and Care
- Cleaning: Clean the crib with a soft, damp cloth and mild soap. Avoid abrasive cleaners or strong chemicals that could damage the finish.
- Inspections: Periodically check all screws, bolts, and fasteners to ensure they are tight. Tighten any loose hardware immediately.
- Storage: If storing the crib, do so in a cool, dry place. Avoid extreme temperatures or humidity.
- Finish: The crib is made from durable wood. Minor scratches can often be touched up with a non-toxic furniture repair pen matching the grey finish.
8. Troubleshooting
- Crib feels wobbly: Ensure all bolts and screws are fully tightened. Re-check assembly steps to confirm all parts are correctly aligned.
- Parts missing or damaged: Do not attempt to use the crib. Contact Delta Children customer support for replacement parts.
