Maintenance and Care
- Mattress Protector: To protect your mattress from stains and spills and to extend its lifespan, it is highly recommended to use a mattress protector.
- Cleaning Spills: We do not recommend applying liquids directly to your mattress. For soiled areas, apply baking soda and let it stand for approximately 15 minutes. Then, vacuum the area. Repeat as needed. Ensure the product is aired out as much as possible after cleaning.
- Avoid Liquids and Chemicals: Applying liquids or harsh chemicals directly to the mattress may stain the fabric, worsen the soiled area, and can cause premature breakdown of the foam, potentially damaging the product.
Troubleshooting
- New Mattress Odor:
- It is common for new mattresses to have a slight odor upon unboxing. Please allow one week of use for your mattress to air out. This process, known as off-gassing, is normal and the odor will dissipate over time.
- Initial Firmness/Comfort:
- Your new mattress may feel firmer than expected initially. Allow approximately one week for the mattress to break in and conform to your body, reaching its intended comfort level.
