Safety Information

Please read and understand all safety information before setting up and using your mattress. Failure to follow these instructions may result in injury or product damage.

  • Keep the mattress away from open flames and high heat sources.
  • Do not jump on the mattress, as this can damage the internal components and void the warranty.
  • Ensure the mattress is placed on a stable and supportive foundation (e.g., slatted bed frame, box spring, platform bed) to maintain its structural integrity and comfort.
  • Keep plastic packaging away from children and pets to prevent suffocation hazards.
  • Allow adequate ventilation during the initial expansion period to dissipate any new product odors.

Setup Instructions

Your ZINUS mattress is conveniently shipped in a box and will expand to its full size after unboxing. Follow these steps for proper setup:

  1. Prepare the Space: Choose a clean, flat surface for unboxing, preferably where the mattress will be used. Ensure there is enough room for the mattress to expand.
  2. Remove from Box: Carefully remove the rolled and compressed mattress from its shipping box.
  3. Unroll the Mattress: Place the rolled mattress on your bed frame or foundation. Carefully cut and remove the outer plastic wrapping. The mattress will begin to unroll.
  4. Remove Inner Plastic: Once unrolled, carefully cut and remove the inner plastic layer. The mattress will immediately begin to expand.
  5. Allow for Full Expansion: Allow 24-72 hours for the mattress to fully expand to its original shape and firmness. While it can be slept on within a few hours, full expansion ensures optimal comfort and support.

Operating Guidelines

To ensure the longevity and optimal performance of your ZINUS mattress, consider the following guidelines:

  • Proper Foundation: Always use your mattress on a sturdy, flat, and supportive foundation. This can include a slatted bed frame with slats no more than 3 inches apart, a box spring, or a solid platform bed. An inadequate foundation can lead to sagging and reduce the lifespan of your mattress.
  • Rotation: To promote even wear and extend the life of your mattress, rotate it 180 degrees every 3-6 months. This helps distribute body weight and pressure more uniformly across the surface.
  • Motion Isolation: The individually wrapped coils are designed to minimize motion transfer, allowing you and your partner to sleep undisturbed.
  • Cooling Comfort: The mattress is designed with cooling features to help regulate temperature for a more comfortable sleep experience.

Maintenance and Care

Proper care will help maintain the quality and comfort of your ZINUS mattress for years to come:

  • Spot Cleaning: For spills or stains, spot clean the mattress immediately using a mild detergent and a damp cloth. Blot the area gently; do not saturate the mattress. Allow it to air dry completely before covering with bedding.
  • Protective Cover: Consider using a mattress protector to shield against spills, stains, and allergens, extending the life of your mattress.
  • Ventilation: Periodically remove bedding and allow the mattress to air out to promote freshness and prevent moisture buildup.
  • Avoid Harsh Chemicals: Do not use harsh cleaning agents, bleach, or abrasive materials on the mattress, as these can damage the fabric and internal components.

Troubleshooting

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

ProblemPossible CauseSolution
Mattress not fully expandingInsufficient time for expansion; cool room temperature.Allow up to 72 hours for full expansion. Ensure the room temperature is at least 68°F (20°C). Walking on the mattress gently can help with air circulation.
New product odor (off-gassing)Normal for new foam products.The odor is harmless and will dissipate. Ventilate the room by opening windows or using a fan. The smell should fade within a few days.
Mattress feels too firm/softPersonal preference; not fully expanded.Allow the mattress to fully expand for 72 hours. Your body may also need time to adjust to a new mattress (typically 2-4 weeks). Ensure you have the correct firmness level for your preference.
Squeaking noisesIssue with bed frame or foundation, not the mattress.Check your bed frame and foundation for loose connections or worn parts. Tighten bolts or apply lubricant to joints as needed.
