Setup Guide
Unboxing Your Mattress
- Prepare Your Space: Clear the area where you intend to place your mattress. Ensure you have enough room for the mattress to expand.
- Remove from Box: Carefully remove the compressed mattress from its shipping box.
- Unroll: Place the rolled mattress on your bed frame or foundation. Carefully cut and remove the outer plastic layer.
- Expand: Unroll the mattress. Cut the inner plastic layer along the edges. The mattress will immediately begin to decompress.
- Allow Full Expansion: Allow 24–72 hours for your mattress to fully expand to its original shape and firmness. Cooler temperatures may require more time.

Usage Guidelines
Optimal Support
For optimal performance and longevity, place your Zinus Ultima mattress on a solid, flat surface such as a platform bed, slatted foundation (with slats no more than 3 inches apart), or a box spring in good condition. This ensures even weight distribution and proper support for the memory foam layers.
Initial Adjustment Period
It is common for new memory foam mattresses to have a slight odor upon unboxing. This 'new mattress smell' is harmless and will dissipate within a few days in a well-ventilated room. Your body may also require a short adjustment period to adapt to the unique feel and support of memory foam.
Care and Maintenance
Cleaning Instructions
- Spot Clean Only: The mattress cover is not removable for machine washing. For spills or stains, gently spot clean the affected area with a mild detergent and a damp cloth. Blot dry thoroughly.
- Avoid Soaking: Do not saturate the mattress with water or cleaning solutions, as this can damage the foam and compromise its integrity.
General Care
- Protect Your Mattress: Use a mattress protector to shield against spills, stains, and allergens, extending the life of your mattress.
- Rotate Regularly: To promote even wear and prolong comfort, rotate your mattress 180 degrees every 3-6 months. This mattress is designed to be used on one side and does not require flipping.
- Ventilate: Periodically air out your mattress by removing bedding to allow for airflow and maintain freshness.
Troubleshooting
Mattress Not Fully Expanding
If your mattress has not fully expanded after 72 hours, ensure it is placed in a warm room, as colder temperatures can slow the expansion process. Gently walk on the mattress or apply light pressure to help break up any compressed areas. If issues persist, contact Zinus customer support.
Unusual Odor
A slight odor is normal for new memory foam products. This is known as 'off-gassing' and is not harmful. To minimize the odor, allow the mattress to air out in a well-ventilated room for several days before use. The green tea and charcoal infusions are designed to help mitigate this over time.
Perceived Firmness
The Zinus Ultima mattress has a medium-firm feel. Individual perception of firmness can vary. Allow a few weeks for your body to adjust to the new mattress and for the foam to fully settle.
