Setup Instructions
Your NChanmar mattress is delivered compressed and rolled in a box for easy transport. Follow these steps for proper setup:
- Move the Box: Carefully move the mattress box to the desired room where it will be used.
- Open the Box: Remove the mattress from its packaging. Be careful not to cut the mattress itself when opening.
- Unfold the Mattress: Unroll the compressed mattress onto your bed base or foundation.
- Allow to Expand: The mattress will begin to inflate immediately upon unrolling. Please allow up to 72 hours for the mattress to fully expand to its original size and firmness. During this time, the mattress may have a slight new product scent, which will dissipate.
Important Note: Once the mattress is unwrapped and expanded, it cannot be re-rolled or compressed back into its original packaging.

Maintenance and Care
Proper care will extend the life and performance of your NChanmar mattress:
- Protective Cover: The mattress is equipped with a durable and soft knitted cloth cover. This cover is designed to absorb moisture and sweat, helping to keep the mattress cool and protected.
- Cleaning the Cover: The back of the mattress cover features a zipper, allowing it to be removed for easier cleaning. Refer to the care label on the cover for specific washing instructions.
- General Care: To maintain hygiene and prolong the mattress's lifespan, it is recommended to use a mattress protector. Rotate the mattress periodically (e.g., every 3-6 months) to ensure even wear, although flipping is generally not required for memory foam mattresses.

Troubleshooting
Here are some common questions and solutions regarding your new mattress:
- Mattress Not Fully Expanding: While the mattress inflates quickly, full expansion can take up to 72 hours. Ensure it is laid flat in a well-ventilated room. Cooler temperatures may slightly prolong expansion time.
- New Product Odor: A slight, harmless odor (off-gassing) may be present upon unpacking. This is normal for new foam products and will dissipate within a few days. Ensure good ventilation in the room.
- Firmness Perception: Memory foam mattresses adapt to your body over time. Initial firmness may feel different than expected. Allow a few nights for your body to adjust to the new mattress and for the foam to fully settle.
