How Long Does Mattress Off-Gassing Last?
That new mattress smell? It’s likely caused by volatile organic compounds (VOCs) releasing from the materials. This process, called off-gassing, usually takes days or weeks to subside entirely. While generally harmless, it can irritate people with chemical sensitivities or respiratory issues.

Minimizing Mattress Off-Gassing:
- Airing Out: Allowing the mattress to breathe in a well-ventilated room for 2-3 days is the most effective way to reduce off-gassing. Open windows and use fans for better circulation.
- Baking Soda: While not eliminating VOCs, baking soda effectively absorbs lingering odors. Sprinkle it on the mattress surface, leave it for an hour, then vacuum thoroughly.
- Sunlight (weather permitting): Exposing the mattress directly to sunlight for a few hours can accelerate the off-gassing process. However, be mindful of sun damage to the mattress fabric.
- Choose Low Off-Gassing Mattress: Opting for a mattress with certifications like CertiPUR-US or made with natural materials like organic cotton or wool significantly reduces off-gassing from the start.
| Method | Timeline | Effectiveness |
|---|---|---|
| Airing Out | 2-3 days | Very Effective |
| Baking Soda | 1 hour | Moderately Effective for odors |
| Sunlight (weather permitting) | A few hours | Moderately Effective for VOCs |
| Choose Low Off-Gassing Mattress | Varies depending on material | Highly Effective |
Additional Notes:
- The timeline provided is an estimate and may vary depending on the mattress type, thickness, and initial VOC levels.
- Combining these methods can further enhance results. For instance, airing out a low off-gassing mattress will significantly reduce off-gassing times.
- If a strong odor persists after several weeks, consider returning the mattress or consulting the manufacturer.
Choosing a Low Off-Gassing Mattress:
Certifications: When shopping for a mattress with minimal off-gassing, certifications are your friend. Look for mattresses certified by organizations that independently test for VOC emissions and other harmful chemicals. Here are some of the top certifications to consider:
- CertiPUR-US®: This non-profit organization tests for emissions of VOCs, formaldehyde, and other chemicals. It also prohibits certain flame retardants and heavy metals in certified mattresses.
- GREENGUARD Gold: This certification goes beyond VOC emissions and also considers chemicals that may off-gas over time. It ensures the mattress meets stricter standards for indoor air quality.
- OEKO-TEX Standard 100: This global certification system focuses on textile safety. It ensures the materials used in the mattress, not just the finished product, meet strict limits for harmful substances.
Natural Materials: Opting for mattresses made with natural materials is another way to minimize off-gassing. Here are some popular natural choices:
- Organic Cotton: This breathable and hypoallergenic material is often used in mattress covers and comfort layers.
- Organic Wool: Naturally flame-retardant and moisture-wicking, wool is a great choice for a comfortable and low-off-gassing sleep surface.
- Natural Latex: Derived from the rubber tree, natural latex offers excellent support and pressure relief. Look for mattresses that use Dunlop or Talalay latex processes, as they typically off-gas less than synthetic latex options.
- Innerspring: Traditional innerspring mattresses typically use less foam and other potentially off-gassing materials compared to all-foam models. However, some innerspring mattresses may still utilize chemical flame retardants or adhesives. Look for models that are certified as mentioned above.
Additional Considerations:
- Reduced Chemical Treatments: Some mattress manufacturers advertise using fewer chemical treatments in their production process. Look for brands that prioritize natural flame retardants like wool or inherent flame resistance properties in the materials.
- Ventilation: Good mattress ventilation helps release VOCs and moisture buildup. Look for mattresses with breathable covers and consider using a slatted bed base to promote airflow underneath the mattress.
By considering certifications, natural materials, and additional factors like ventilation, you can increase your chances of finding a low off-gassing mattress that promotes a healthier sleep environment.
Still Have Concerns?
If you have respiratory problems or chemical sensitivities and worry about off-gassing, consulting a healthcare professional is recommended. They can advise you on the best course of action for your individual needs.
