Nautica Home Serenity 12-Inch Queen Memory Foam Mattress Instruction Manual
Model: 4120
Introduction
This manual provides essential information for the setup, use, and maintenance of your Nautica Home Serenity 12-Inch Queen Memory Foam Mattress. Please read these instructions carefully to ensure optimal performance and longevity of your mattress.
Setup
Your Nautica Home Serenity mattress is compressed and rolled for convenient shipping. Follow these steps for proper unboxing and expansion:
- Preparation: Place the packaged mattress box in the room where it will be used. Ensure you have enough space to unroll the mattress on a clean, flat surface, such as your bed frame or foundation.
- Unboxing: Carefully open the outer carton. Inside, you will find the rolled mattress encased in plastic, along with a small cutting tool and instructions.
- Unrolling: Remove the rolled mattress from the box and place it on your bed frame. Carefully unroll the mattress.
- Cutting the Plastic: Use the provided cutting tool to carefully cut and remove the outer layer of thick plastic. The tool is designed to cut the plastic without damaging the mattress.
- Expansion: Once the plastic is removed, the mattress will begin to decompress and expand. Allow 48 to 72 hours for the mattress to fully expand to its intended size and firmness. During this time, the mattress may appear slightly wrinkled, which will smooth out as it expands.

Operating (Features)
The Nautica Home Serenity mattress is designed for optimal sleep comfort and support, incorporating multiple layers and advanced materials:
- Instant-Cooling IceLux Cover: The top cover features IceLux fabric, which feels cool to the touch and actively wicks away heat throughout the night. It includes a 360° zipper for easy removal and machine washing.
- 2-Inch MicroTec Gel Memory Foam: This layer is infused with cooling gel and features precision ventilation to dissipate excess warmth, while cradling pressure points for enhanced comfort.
- 1-Inch Contour Transition Foam: Designed to adapt to your body's curves, this foam layer helps maintain spinal alignment and minimizes motion transfer for undisturbed rest.
- 3-Inch Gellux Engineered Latex: A proprietary blend of liquid-gel and latex provides a buoyant and responsive feel, preventing the sensation of sinking into the mattress.
- EdgePlus + 6-Inch Channel-Vented Base: A patented perimeter tray maximizes the usable sleeping surface and resists sagging. The high-density base includes airflow channels to further enhance cooling and overall durability.

Maintenance
Proper care will extend the life of your Nautica Home Serenity mattress:
- Removable Cover: The IceLux cover can be unzipped and machine-washed for a fresh sleeping surface. Follow the care instructions on the label for best results.
- Spot Cleaning: For minor spills or stains on the mattress core (if the cover is removed), gently spot clean with a mild detergent and water. Blot dry thoroughly. Do not saturate the mattress.
- Ventilation: Ensure adequate airflow around the mattress to prevent moisture buildup.
- Rotation: Rotate your mattress every 3-6 months to promote even wear and extend its lifespan.
Troubleshooting
If you encounter any issues with your Nautica Home Serenity mattress, consider the following:
- Odor: A new mattress may have a slight odor upon unboxing. This is normal and will dissipate within a few days in a well-ventilated room.
- Incomplete Expansion: If the mattress has not fully expanded after 72 hours, ensure it is on a flat surface and allow a few more days. Cooler temperatures can sometimes slow the expansion process.
- Comfort Issues: Allow your body time to adjust to the new mattress, typically a few weeks. The medium-plush comfort level is designed to provide a balance of support and softness.
