Frequently asked questions
What firmness is best for a side sleeper?
Side sleepers generally need a medium-soft to medium firmness (4-6 on the firmness scale) to cushion the hips and shoulders. Too firm can cause pressure points, while too soft can lead to spinal misalignment.
How do cooling mattresses work?
Cooling mattresses use materials like phase-change gels, gel-infused foams, breathable covers, and open-cell foams to dissipate body heat. Hybrid designs with pocketed coils improve airflow compared to all-foam models.
Are cooling mattresses safe?
Yes, but look for certifications like CertiPUR-US and OEKO-TEX to ensure low VOC emissions and no harmful chemicals. These standards ensure the foams are safe for indoor use.
Can a cooling mattress help with night sweats?
Yes, cooling mattresses can reduce heat retention and wick away moisture, helping regulate temperature. Owners often report less sweating compared to traditional mattresses.
How long does a cooling mattress last?
With proper care, a quality cooling mattress can last 7-10 years. Hybrid and latex models tend to be more durable than all-foam. Look for warranties of at least 10 years.
