Safety Information
- Keep all packaging materials, especially plastic bags, away from children and pets to prevent suffocation hazards.
- Do not use sharp objects to open the mattress packaging, as this may damage the mattress fabric.
- Ensure the mattress is placed on a stable, supportive bed frame or foundation.
- The twin mattress supports a maximum weight of 250 lbs. Do not exceed this weight limit.
- Avoid exposing the mattress to open flames or high heat sources.
- This mattress is made with CertiPUR-US certified foam and OEKO-TEX certified fabric, ensuring it is free from harmful chemicals.
Setup Guide
Your ZINUS mattress is compressed and rolled for convenient shipping. Follow these steps for proper setup:
- Unpack the Mattress: Carefully remove the mattress from its shipping box. Place the rolled mattress on the bed frame or flat surface where it will be used.
- Remove Plastic Wrapping: Carefully cut and remove the outer plastic wrapping. Be cautious not to cut the mattress fabric. The mattress will begin to decompress immediately.
- Allow for Full Expansion: Unroll the mattress completely. It may take up to 48-72 hours for the mattress to fully expand to its intended 6-inch height. While it will expand significantly within minutes, allowing the full time ensures optimal comfort and support.
- Initial Odor: A slight, harmless odor may be present upon unboxing due to the compression process. This is normal and will dissipate within a few hours in a well-ventilated room.
