Introduction
This manual provides essential information for the setup, use, and maintenance of your ZINUS 8 Inch Twin Cooling Essential Memory Foam Mattress. Designed for comfort and support, this mattress features breathable cooling layers and is crafted with certified safe materials.
Setup
Your ZINUS mattress is compressed and rolled for convenient shipping. Upon arrival, carefully remove the mattress from its packaging. Place the rolled mattress on a flat, clean surface, such as your bed frame or foundation. Carefully cut open the outer plastic wrap, being cautious not to cut the mattress itself. The mattress will begin to decompress immediately. Allow 24 to 72 hours for the mattress to fully expand to its original shape and firmness. Optimal expansion occurs in a well-ventilated room.

Operating
The ZINUS 8 Inch Twin Cooling Essential Memory Foam Mattress offers a medium-firm feel, designed to provide balanced support and pressure relief. The gel-infused Airflow Memory Foam top layer promotes breathability and conforms to your body's contours, enhancing circulation.
Sleeping Positions
- Back Sleepers: This mattress provides firm support, which can be beneficial for maintaining spinal alignment for back sleepers. The foam layers will conform to the natural curve of your spine without excessive sinking.
- Stomach Sleepers: The firmer nature of this mattress helps prevent the midsection from sinking too deeply, which is crucial for stomach sleepers to maintain proper spinal alignment and reduce strain on the lower back.
- Side Sleepers: While this mattress offers a firmer feel, the memory foam layers provide some pressure relief for hips and shoulders. Individuals who prefer a softer feel for side sleeping may consider adding a mattress topper or exploring other mattress options.

Maintenance
To ensure the longevity and hygiene of your ZINUS mattress, follow these maintenance guidelines:
- Spot Cleaning: For minor spills or stains, spot clean the affected area using a mild detergent and a damp cloth. Avoid saturating the mattress with water. Blot gently and allow to air dry completely before covering.
- Removable Cover: The mattress features a removable cover. Refer to the care label on the cover for specific washing instructions. Typically, machine washing in cold water on a gentle cycle and air drying is recommended. Ensure the cover is completely dry before placing it back on the mattress.
- Protection: Using a mattress protector is highly recommended to shield against spills, stains, and allergens, extending the life of your mattress.
- Rotation: To promote even wear and maintain consistent support, rotate your mattress 180 degrees every 3-6 months. This helps distribute body weight evenly across the surface.

Troubleshooting
If you encounter any issues with your ZINUS mattress, consider the following common solutions:
Issue | Possible Cause | Solution |
---|---|---|
Mattress Not Fully Expanded | Insufficient time for decompression. | Allow up to 72 hours for full expansion. Ensure the mattress is in a well-ventilated room and is laid flat. |
Odor upon Unboxing | "Off-gassing" from new foam materials. | This is normal and harmless. Allow the mattress to air out in a well-ventilated room for a few days. The odor will dissipate. |
Mattress Feels Too Firm | Personal preference or newness of the foam. | Memory foam mattresses may feel firmer initially and soften slightly with use. If after a few weeks it remains too firm for your preference, a mattress topper can be added for additional plushness. |
