The mattress is constructed with water-resistant and skin-friendly flocking and a PVC double-layer structure, ensuring durability and comfort. Its patented column structure offers stable support, alleviating pressure points for a restful sleep. The non-slip bottom enhances stability, preventing unwanted movement.
2. Safety Information
WARNING: To reduce the risk of electric shock or injury, please read and follow all instructions carefully.
- After the first inflation, allow the PVC material to stretch out for 10 hours before initial use. A small amount of air may need to be added daily during this period.
- Do not exceed the maximum weight capacity of 300 kg (661 lbs).
- Ensure the pump is correctly turned off after inflation or deflation.
- Use the pump indoors only. Do not use the pump continuously for over 5 minutes. Take a 10-minute break before you use it again.
- Always follow proper inflation and deflation procedures to avoid damage or injury.

4. Setup (Inflation)
Your Lewondr air mattress features a convenient built-in electric pump for quick and easy inflation.
- Unroll the air mattress on a clean, flat surface, ensuring it is free from sharp objects.

- Open the compartment cover to access the power cord and the inflation/deflation dial.
- Plug the power cord into a grounded 110-120V AC electrical outlet.
- Turn the dial clockwise to the "INFLATE" position. The mattress will begin to inflate automatically.
- Allow approximately 3 minutes for the mattress to reach full firmness. You can adjust the firmness to your preference by stopping the pump earlier or adding more air.

5. Operating (Usage & Deflation)
5.1 Usage
Once inflated, your Lewondr Queen Air Mattress is ready for use. Its 18-inch height provides a comfortable sleeping surface, similar to a traditional bed. The flocked top surface is soft and helps keep sheets in place. Side pockets are included for convenient storage of small items like phones or remote controls.

5.2 Deflation and Storage
When you are ready to store the mattress, the built-in pump also facilitates quick deflation.
- Ensure the mattress is on a clean, flat surface.
- Plug the power cord into a grounded 110-120V AC electrical outlet.
- Turn the dial counter-clockwise to the "DEFLATE" position. The pump will automatically begin to remove air from the mattress.
- Once the mattress is fully deflated, turn the dial to the "OFF" position and unplug the power cord.
- Fold the deflated mattress neatly and place it into the provided storage bag (storage size: 27'' x 22'').

6. Maintenance
To ensure the longevity of your Lewondr air mattress, follow these simple maintenance guidelines:
- Cleaning: The flocked surface is easy to clean. Use a damp cloth with mild soap and water to wipe down the surface. Avoid harsh chemicals or abrasive cleaners.
- Storage: Store the deflated mattress in its storage bag in a cool, dry place, away from direct sunlight and extreme temperatures.
- Puncture Repair: In case of a small puncture, use the included repair stickers. Clean the area around the puncture, apply the sticker firmly, and allow it to set for several hours before re-inflating.

7. Troubleshooting
If you encounter any issues with your air mattress, please refer to the following common solutions:
- Mattress feels like it's losing air: During the first few uses, the PVC material will stretch. This is normal and may feel like a leak. Add a small amount of air daily until the product is fully extended and the material stabilizes.
- Pump not working: Ensure the power cord is securely plugged into a functional 110-120V outlet. Check that the dial is correctly set to either "INFLATE" or "DEFLATE" and not in the "OFF" position.
- Pump overheating: Do not use the pump continuously for more than 5 minutes. Allow it to cool down for 10 minutes before resuming operation.
