4. Care and Use
4.1 General Care
- Mattress Protector: To protect your mattress from stains and spills, and to help with its overall health and lifespan, we highly recommend using a mattress protector.
- Rotation: Regularly rotating your mattress (head to foot) can help promote even wear and extend its life.
4.2 Cleaning Instructions
- Spot Cleaning: For soiled areas, apply baking soda directly to the stain and let it stand for approximately 15 minutes. Then, vacuum the area and repeat as needed.
- Air Out: It is important to air the product out as much as possible, especially after cleaning.
- Avoid Liquids: We do not recommend applying liquids directly to the mattress. Applying liquids may stain the fabric and could potentially worsen the soiled area. Moisture or chemicals applied directly to the mattress can cause premature breakdown of the foam and damage the product.
5. Troubleshooting & FAQs
5.1 Common Questions
- Q: My new mattress smells. What can I do?
A: Please allow one week of use for your mattress to reach its maximum comfort while it breaks in and airs out. This initial odor is normal and will dissipate. - Q: How do I clean my mattress?
A: We do not recommend applying liquids to your mattress. Instead, utilize baking soda and vacuum off after 15 minutes for spot cleaning. Utilizing a mattress protector is the best option for preventing stains. - Q: What kind of foundation do I need?
A: Our Serta Foundation, traditional box springs, platform frames with no more than 2" between slats, or adjustable bases all work well. Please refer to Serta's Mattress Warranty Information for all guidelines on foundation requirements.
