3. Setup and Unboxing
Your ZINUS 5 Inch Memory Foam Mattress is delivered compressed and rolled in a box for ease of transport and setup. Follow these steps for optimal mattress expansion and readiness:
- Preparation: Ensure you have a clean, flat surface where you intend to place the mattress, such as a platform bed, foundation, bed frame, or SmartBase®.
- Unbox and Unroll: Carefully open the box and remove the compressed mattress. It is recommended to unbox and unroll the mattress within 72 hours of receipt to ensure proper expansion.
- Allow for Decompression: Once unrolled, the mattress will begin to decompress. You may gently crawl, walk, or jump on the mattress to help facilitate this process.
- Full Expansion: While the mattress will expand significantly within a few hours, it may take up to 72 hours to fully decompress and reach its original shape and firmness. Avoid using the mattress for extended periods until it has fully expanded.

4. Care & Maintenance
Proper care and maintenance will extend the life and comfort of your ZINUS Memory Foam Mattress.
- Cover Care: The mattress features a removable terry fabric cover. For cleaning, the care instructions specify Hand Wash Only. Do not machine wash or tumble dry, as this may damage the fabric or moisture barrier.
- Spot Cleaning: For minor spills or stains on the mattress foam (after removing the cover), gently spot clean with a mild detergent and water. Blot the area dry thoroughly. Avoid saturating the foam.
- Ventilation: To maintain freshness and prevent moisture buildup, periodically air out your mattress by removing bedding. The green tea infusion helps with odor control, but good ventilation is always beneficial.
- Protection: While the cover offers a moisture barrier, using a mattress protector is highly recommended for additional protection against spills, stains, and allergens, further extending the mattress's lifespan.
- Rotation: To ensure even wear and prolong the mattress's life, rotate it 180 degrees every 3-6 months. This helps distribute pressure evenly across the sleeping surface.
5. Troubleshooting
Most common issues with memory foam mattresses are related to initial setup and environmental factors. Here are some tips:
- Mattress Not Fully Expanding: If your mattress does not appear to have reached its full 5-inch thickness after 72 hours, ensure it was unboxed and unrolled on a flat surface in a room with a comfortable temperature (around 68-72°F or 20-22°C). Cooler temperatures can slow down the expansion process. Allow a few more days for full expansion, especially in colder environments. Gentle walking or rolling on the mattress can also help stimulate air flow within the foam.
- New Mattress Odor: A slight, harmless odor (often described as a
