2. Setup Instructions

  1. Unpack the Mattress: Carefully remove the mattress from its shipping box. Place the rolled and compressed mattress on a clean, flat surface, such as your bed frame or foundation.
  2. Remove Packaging: Gently cut open the outer plastic wrapping. Be careful not to cut the mattress fabric. The mattress will begin to decompress as air fills the foam layers.
  3. Allow for Expansion: Unroll the mattress completely. It may take 24 to 72 hours for the mattress to fully expand to its original shape and firmness. During this time, the mattress may have a slight odor, which is normal and will dissipate. Ensure good ventilation in the room.
  4. Prepare for Use: Once fully expanded, the mattress is ready for use. You may notice that your mattress arrives with one of two distinct covers; both provide the same supportive feel.

4. Maintenance

Proper care will extend the life of your ZINUS mattress.

  • Spot Clean Only: For spills or stains, use a mild detergent and a damp cloth to gently spot clean the affected area. Do not saturate the mattress.
  • Avoid Harsh Chemicals: Do not use harsh cleaning agents or abrasive brushes, as these can damage the mattress fabric and foam.
  • Protect Your Mattress: Consider using a mattress protector to shield against spills, stains, and allergens.
  • Rotation: While not strictly required, rotating your mattress every 3-6 months can help promote even wear and extend its lifespan.

5. Troubleshooting

If you encounter any issues with your ZINUS mattress, please refer to the following common solutions:

  • Odor upon Unboxing: A new mattress may have a slight, harmless odor (off-gassing) after unboxing. This is normal and will dissipate within a few days. Ensure good ventilation in the room.
  • Incomplete Expansion: If the mattress has not fully expanded after 72 hours, ensure it is placed on a flat surface in a well-ventilated room. Cooler temperatures can slow expansion; a warmer room may help. Contact customer support if expansion issues persist.
  • Perceived Firmness/Softness: Mattress feel is subjective. Allow a few weeks for your body to adjust to the new mattress. If the feel is significantly different from expected, ensure the mattress has fully expanded.
