- Unbox the Mattress: Carefully remove the mattress from its shipping box.

- Remove Outer Plastic: Carefully cut and remove the outer plastic wrapping. Avoid using sharp objects that could damage the mattress fabric.

- Remove Inner Plastic: Cut and remove the inner plastic layer. The mattress will continue to expand.
- Allow Full Expansion: Allow 48 to 72 hours for the mattress to fully expand to its intended size and firmness. Ventilation in the room can aid this process.

Maintenance
To maintain the quality and longevity of your Zinus mattress, follow these simple care instructions:
- Spot Clean Only: For spills or stains, clean the affected area using a mild detergent and a damp cloth. Do not saturate the mattress.
- Avoid Harsh Chemicals: Do not use harsh cleaning agents or abrasive materials, as these can damage the mattress fabric and foam.
- Rotate Regularly: To promote even wear and extend the mattress lifespan, rotate the mattress 180 degrees every 3-6 months.
- Use a Mattress Protector: A waterproof mattress protector is highly recommended to shield against spills, stains, and allergens, preserving the mattress's condition.
- Ensure Proper Support: Always use your mattress on a supportive bed frame or foundation to prevent sagging and maintain structural integrity.
Troubleshooting
While Zinus mattresses are designed for durability and comfort, here are some common concerns and potential solutions:
- Slow Expansion: If the mattress does not fully expand within 72 hours, ensure it is in a well-ventilated room and has been completely freed from all packaging. Cooler temperatures can slow expansion; allow more time in such conditions.
- New Mattress Odor: A faint odor, often referred to as 'off-gassing,' is normal for new foam products. This typically dissipates within a few days in a well-ventilated room.
- Uneven Feel: Ensure the mattress is placed on a flat, supportive surface. Rotating the mattress regularly can help distribute wear evenly. If issues persist, refer to the warranty information.
- Noise from Springs: While hybrid mattresses are designed to minimize noise, ensure the bed frame is stable and all connections are tightened.
