Introduction
This manual provides essential information for the setup, operation, maintenance, and care of your ZINUS 12 Inch Full Cooling Comfort Hybrid Mattress. Please read these instructions thoroughly before use to ensure optimal performance and longevity of your product.
The ZINUS 12 Inch Full Cooling Comfort Hybrid Mattress features a combination of pressure-relieving memory foam and individually wrapped coils. The memory foam layer is infused with cooling gel to help regulate temperature, while the coil system provides motion isolation and customized support. The mattress is encased in a soft, breathable OEKO-TEX® certified cover. All foams used are Certi-PUR US® certified, ensuring they are made without harmful chemicals.
Setup Instructions
- Unpack the Mattress: Carefully remove the mattress from its shipping box. The mattress is compressed and rolled for convenient delivery.
- Position the Mattress: Place the rolled mattress on a clean, flat surface, such as your bed frame or foundation. Ensure there is enough space for it to expand.
- Remove Packaging: Carefully cut and remove the outer plastic wrapping. Avoid using sharp objects that could damage the mattress fabric.
- Allow for Expansion: Unroll the mattress and remove the inner plastic layer. The mattress will begin to expand immediately. Allow 24 to 72 hours for the mattress to fully decompress and reach its original shape and firmness. Initial expansion may vary based on room temperature and humidity.

Operating Characteristics
Your ZINUS Hybrid Mattress is designed to provide a balanced sleep experience with specific features:
- Medium Firm Feel: This mattress offers a medium-firm feel, providing a balance of comfort and support suitable for various sleep preferences.
- Cooling Comfort: The top layer of memory foam is infused with cooling gel to dissipate heat and maintain a comfortable sleep temperature throughout the night.
- Motion Isolation: Individually wrapped coils minimize motion transfer, reducing disturbances from a partner's movements.
- Pressure Relief: The memory foam conforms to your body's contours, alleviating pressure points and promoting spinal alignment.

Maintenance
- Spot Clean Only: For spills or stains, clean the affected area using a mild detergent and a damp cloth. Blot gently; do not saturate the mattress.
- Do Not Remove Cover: The mattress cover is an integral part of the fire safety barrier. Removing the cover can compromise the mattress's fire retardant properties and will void the product warranty.
- Protect Your Mattress: Consider using a mattress protector to shield against spills, stains, and allergens, extending the life of your mattress.
- Rotation: While not strictly required for hybrid mattresses, rotating your mattress 180 degrees every 3-6 months can help promote even wear and prolong its lifespan.
Troubleshooting
- Slow Expansion: If your mattress has not fully expanded after 72 hours, ensure it is in a well-ventilated room with a comfortable temperature. Cooler temperatures can slow down the expansion process. Allow additional time if necessary.
- Initial Odor: A new mattress may have a slight, harmless odor upon unboxing. This is normal and will dissipate within a few days in a well-ventilated room.
- Firmness Perception: Mattress firmness is subjective. If the mattress feels firmer than expected, allow more time for it to break in with regular use.
