Setup Instructions
Your Dyonery mattress is conveniently shipped in a box, compressed and rolled for easy transport. Follow these steps for proper setup:
- Unbox the Mattress: Carefully remove the mattress from its shipping box. Place the rolled mattress on your bed frame or desired flat surface.
- Unroll and Unseal: Gently unroll the mattress. Cut and remove the outer plastic wrapping. The mattress will begin to expand immediately.
- Allow for Full Expansion: For optimal comfort and to allow the mattress to reach its full 14-inch height and intended firmness, allow it to expand for at least 12 hours. Some mattresses may take up to 72 hours to fully decompress.

Product Features
The Dyonery EGOBLACK mattress is engineered with multiple layers and advanced materials for a supportive and comfortable sleep experience.
- Cooling Knit Fabric Cover: The mattress features a cooling knit fabric cover designed to regulate body temperature, keeping you comfortable throughout the night. This fabric is smooth, absorbent, and promotes sweat evaporation for a dry sleeping surface.
- 2-Layer Memory Foam System: This mattress incorporates a two-layer memory foam system, including copper-infused AeroFusion memory foam. This design cradles your body, reduces pressure points, and minimizes sleep disruptions.
- CertiPUR-US & Oeko-Tex Standard 100 Certified: All foams and fabrics are independently evaluated to meet strict safety standards, ensuring they are free from harmful substances. The mattress is also fiberglass-free.

Troubleshooting
Here are some common questions and solutions regarding your new mattress:
- Slow Expansion: If your mattress does not fully expand within 12 hours, allow up to 72 hours. Temperature and humidity can affect expansion time.
- Initial Discomfort: It is common to experience a period of adjustment when switching to a new mattress, especially a firm memory foam mattress. Allow 1-2 weeks for your body to adapt to the new support.
- Odor: A new mattress may have a slight odor upon unboxing. This is normal and will dissipate within a few days in a well-ventilated room.
