Introduction
The ZINUS 12 Inch Cooling Comfort Support Hybrid Mattress is engineered for optimal comfort and support, providing a rejuvenating sleep experience.

Setup Guide
Your ZINUS mattress is conveniently packaged in a compact box for easy delivery. Please follow these steps for proper setup:
- Unboxing: Carefully remove the mattress from its compact packaging. While manageable by one person, having two people may be beneficial, especially if navigating stairs, due to the mattress's weight.
- Placement: Position the rolled mattress onto your bed frame or foundation.
- Unrolling: Carefully cut open the plastic wrapping. The mattress will begin to unroll and expand on its own.
- Expansion: Allow 24 to 72 hours for the mattress to fully expand to its original shape and firmness. While it may appear mostly expanded within 24 hours, the full 72-hour period ensures complete expansion and optimal comfort.
- Ventilation: During the expansion period, minimal to no off-gassing odor is expected. However, ensuring good room ventilation can further enhance the experience.

Maintenance
To ensure the longevity and continued comfort of your ZINUS mattress, please adhere to the following maintenance guidelines:
- Cleaning: The mattress cover is spot clean only. Use a mild detergent and a damp cloth to gently clean any spills or stains. Avoid saturating the mattress with water.
- Protection: We recommend using a mattress protector to shield your mattress from spills, stains, and allergens, extending its lifespan.
- Rotation: To promote even wear and prolong the mattress's life, rotate your mattress 180 degrees every 3-6 months. This helps distribute body weight evenly.
- Support: Ensure your mattress is placed on a sturdy, supportive bed frame or foundation to maintain its structural integrity.
Troubleshooting
If you encounter any issues with your ZINUS mattress, consider the following common solutions:
- Incomplete Expansion: If your mattress has not fully expanded after 24 hours, allow the full 72-hour period. Ensure it is laid flat in a well-ventilated room. Cooler temperatures can sometimes slow down expansion.
- Initial Firmness: Some users may find the mattress initially firmer than expected. This is normal, and the mattress may soften slightly with use. Allow a few weeks for your body to adjust to the new support.
- Side Firmness: If the sides or corners appear less firm initially, this can improve as the mattress fully expands and settles over the first week or two.
- Heat Retention: While designed with cooling features, individual perceptions of temperature can vary. Ensure your bedding is breathable and your room temperature is comfortable.
