Setup and Unboxing
Your MLILY Tri-Fold Memory Foam Mattress is delivered compressed and rolled in a box. Follow these steps for initial setup:
- Unbox: Carefully remove the mattress from its packaging. Avoid using sharp objects that could damage the fabric.
- Unroll: Place the compressed mattress on a clean, flat surface and unroll it.
- Expand: Allow the mattress to expand fully. This process typically takes 24 to 48 hours, though it may vary based on room temperature and humidity. The mattress will reach its intended dimensions and firmness during this time.
- Enjoy: Once fully expanded, your mattress is ready for use.

Operating and Usage
The tri-fold design offers flexibility for various uses:
- Unfolding: To use as a full mattress, simply lay it flat on the floor or a suitable surface. Ensure all three sections are fully extended.
- Folding for Storage: Fold the mattress into three sections. The compact size allows for easy storage in closets, under beds, or in vehicles.
- Folding for Seating: The mattress can be folded into a cube shape to serve as a temporary seat or ottoman.

Care and Maintenance
Proper care will extend the life of your MLILY Tri-Fold Memory Foam Mattress:
- Cover Cleaning: The mattress cover is removable and washable. Hand wash only. Do not bleach. Air dry thoroughly. Ensure the cover is completely dry before placing it back on the foam.
- Foam Care: The memory foam core should not be washed. If the foam becomes soiled, spot clean with a mild detergent and water, then allow it to air dry completely away from direct sunlight or heat.
- Ventilation: Periodically air out the mattress to maintain freshness and prevent moisture buildup.
- Protection: Consider using a mattress protector to shield the foam from spills and stains, especially during outdoor use.
Troubleshooting
Here are solutions to common concerns:
- New Product Odor: A faint odor, often referred to as "new foam smell," is normal and harmless. It will dissipate within a few days of unboxing and airing out the mattress in a well-ventilated area.
- Incomplete Expansion: If the mattress does not fully expand within 48 hours, ensure it is in a warm room (above 65°F / 18°C) and has ample space to breathe. Continued lack of expansion may indicate an issue; refer to warranty information.
- Firmness Perception: Memory foam mattresses adapt to body heat and pressure. Initial firmness may feel different until the foam adjusts to your body.
