Setup
Your ZINUS mattress is expertly compressed and rolled for convenient shipping and easy maneuverability. Follow these steps for proper setup:
- Unbox: Carefully remove the mattress from its packaging. It is recommended to open the box within 72 hours of receipt.
- Unroll: Place the compressed mattress on your desired bed frame, foundation, or SmartBase. Unroll the mattress completely.
- Decompress: Allow 24 to 72 hours for the mattress to fully regain its shape and expand to its original size. The expansion time may vary depending on the surrounding room temperature; warmer rooms generally facilitate faster expansion.
- Accelerate Expansion: Gently walking, jumping, or sleeping on the mattress can help speed up the decompression process.

Operating Features
The ZINUS Ultra Cooling Gel Memory Foam Mattress is engineered with advanced features for optimal comfort and temperature regulation:
- Triple Cooling Performance: This mattress is designed to provide three times more cooling benefits than standard cooling gel mattresses, ideal for those who sleep warm.
- Cooling Gel-Infused Memory Foam: A top layer of gel-infused foam actively works to regulate your body temperature, ensuring a cooler night's sleep.
- 7-Zone Ventilation System: The patented ventilation system in the top layer promotes superior airflow throughout the mattress, enhancing breathability and providing targeted pressure relief.
- Cool-to-Touch Soft-Knit Cover: The mattress is wrapped in a performance fabric cover that delivers an immediate cool sensation upon contact, further improving ventilation without feeling chilly.
- Green Tea Infusion: Premium green tea is infused into every layer of the mattress, contributing to freshness from the moment it's unboxed and throughout its lifespan.

Maintenance
To ensure the longevity and performance of your ZINUS mattress, please observe the following maintenance guidelines:
- Mattress Covers: Do not remove the mattress covers. Removing them could harm the fire safety barrier and will void the product warranty.
- Cleaning: For spills or stains, spot clean with mild soap and water. Avoid saturating the mattress. Allow to air dry completely before covering with bedding.
- Protection: Consider using a mattress protector to shield against spills, allergens, and general wear and tear.
- Rotation: While not strictly necessary for memory foam mattresses, rotating your mattress every 6-12 months can help promote even wear and extend its lifespan.
Troubleshooting
If you encounter any issues with your ZINUS mattress, refer to the common concerns and solutions below:
| Problem | Possible Cause | Solution |
|---|---|---|
| Mattress not fully expanding | Insufficient decompression time; cold room temperature. | Allow up to 72 hours for full expansion. Ensure the room is at a comfortable temperature (above 65°F/18°C). Gently walk or jump on the mattress to aid the process. |
| Unusual odor (off-gassing) | New mattress odor from manufacturing and packaging. | This is normal and harmless. The odor should dissipate within a few days. Ensure good ventilation in the room by opening windows. |
| Mattress feels too warm | Individual body temperature; bedding materials. | While designed for cooling, individual experiences may vary. Ensure your room is well-ventilated. Use breathable sheets and bedding made from natural fibers. |
| Discomfort or pressure points | Insufficient adjustment period; improper support base. | Allow your body time to adjust to the new mattress, typically a few weeks. Ensure your bed frame or foundation provides adequate, even support. |
