Introduction
The Zinus Ultima 12 Inch Queen Memory Foam Mattress is designed to provide pressure relief and comfort. This mattress features memory foam infused with green tea and charcoal for freshness, and a 7-zone comfort system for targeted support. All foams are CertiPUR-US® certified, ensuring quality and safety. This manual provides essential information for setting up, using, maintaining, and troubleshooting your new mattress.
Setup
Unboxing and Expansion
Your Zinus Ultima mattress arrives compressed and rolled in a compact, carbon-friendly box. Carefully remove the mattress from its packaging. Place the rolled mattress on your bed frame or a flat, clean surface before cutting the outer plastic. Once the plastic is removed, the mattress will begin to decompress. Allow 24 to 72 hours for the mattress to fully expand to its original shape and firmness. Cooler temperatures may extend the expansion time.

The Zinus Ultima mattress is shipped in a smaller box to reduce its carbon footprint, making it easier to handle and transport.

Bed Frame Compatibility
This mattress is compatible with most standard bed frames, including platform beds with slats, box springs, and adjustable bases. Ensure your bed frame provides adequate support to prevent sagging and maintain the mattress's integrity.
Operating
Comfort and Support
The Ultima Memory Foam Mattress features a medium-firm feel, designed to gently cradle your body and alleviate pressure points. Its patented 7-zone comfort system targets specific areas of your body for optimal support and a restorative sleep experience.

The patented custom contour support system adapts to your body's natural curves, providing personalized pressure relief.

The 7-zone comfort system is engineered to provide targeted pressure relief where your body needs it most, promoting restful sleep.
Freshness and Breathability
The memory foam is infused with all-natural green tea and charcoal, which work together to maintain freshness and help regulate temperature throughout the night. The breathable design prevents overheating, contributing to a comfortable sleep environment.

Internal airflow and infusions contribute to both pressure relief and sustained freshness within the mattress layers.

Key features include green tea infusion for freshness, a soft and breathable cover for comfort, and memory foam for soothing pressure relief.
Maintenance
Cleaning Instructions
The Zinus Ultima mattress should be spot cleaned only. Use a mild detergent and a damp cloth to gently clean any soiled areas. Avoid saturating the mattress with water or harsh chemicals, as this can damage the foam and void the warranty. Allow the cleaned area to air dry completely before covering the mattress.
General Care
- Mattress Protector: Using a waterproof mattress protector is highly recommended to shield your mattress from spills, stains, and allergens, extending its lifespan.
- Rotation: Rotate your mattress every 3-6 months to ensure even wear and prolong its comfort life. This helps distribute body weight more uniformly.
- Ventilation: Periodically air out your mattress by removing bedding to allow for better air circulation, especially during the initial expansion period.
Troubleshooting
Mattress Not Fully Expanding
If your mattress does not appear to have fully expanded after 24 hours, allow additional time. Full expansion can take up to 72 hours, especially in cooler environments. Ensure the mattress is laid flat on a solid surface during this period. Lightly walking on the mattress or gently massaging the foam can sometimes assist in the expansion process.
New Product Odor
It is normal for a new memory foam mattress to have a slight odor upon unboxing. This is known as 'off-gassing' and is harmless. The odor should dissipate within a few days in a well-ventilated room. To expedite this, you can remove all bedding and allow the mattress to air out.
