Setup and Installation

Usage Guidelines
This mattress is engineered with two distinct sides to cater to the developmental needs of your child:
- Infant Side: For newborns and infants, use the firmer side of the mattress. This firm support is crucial for proper spinal development and to reduce the risk of SIDS.
- Toddler Side: As your child grows into a toddler, you can flip the mattress to the softer side. This side features an additional layer of soy foam for enhanced comfort, providing a more plush sleeping surface while still offering adequate support.
Always ensure the correct side is facing up based on your child's age and developmental stage. Regularly check the mattress for proper fit within the crib to ensure safety.

Maintenance and Care
Proper care will extend the life of your Simmons Kids SlumberTime Naturally mattress:
- Cleaning: The mattress cover is waterproof and designed for easy cleaning. For spills or accidents, spot clean the cover using a mild soap and water solution. The manufacturer specifies "Hand Wash Only" for the cover. Do not machine wash or tumble dry.
- Drying: Allow the mattress cover to air dry completely before placing bedding back on.
- Rotation: Periodically rotate the mattress (end-to-end) to promote even wear and extend its lifespan.
- Protection: While the cover is waterproof, using an additional fitted waterproof crib sheet can provide an extra layer of protection and convenience for daily cleaning.

Troubleshooting
Most issues with a crib mattress relate to fit or cleanliness. If you encounter any concerns, consider the following:
- Improper Fit: Ensure the mattress fits snugly within the crib. There should be no more than two fingers' width between the mattress and the crib frame. If gaps exist, re-check the crib assembly or consult your crib's manual.
- Odor: Upon initial unboxing, a slight odor may be present due to packaging. This is normal and will dissipate quickly in a well-ventilated area.
- Stains/Spills: Refer to the "Maintenance and Care" section for cleaning instructions. Promptly addressing spills will prevent permanent staining.
- Comfort Concerns: Remember the mattress has an infant side (firmer) and a toddler side (slightly softer). Ensure the appropriate side is in use for your child's age.
