Frequently asked questions
What makes a 12-inch green tea memory foam mattress different?
Green tea extract is infused into the foam to neutralize odors and provide a fresher sleep surface. The 12-inch profile often indicates additional layers for support or cooling.
Are these mattresses safe?
Most reputable models are CertiPUR-US certified for low VOCs and OEKO-TEX Standard 100 for no harmful chemicals. Always check certifications before purchase.
Do green tea mattresses sleep cooler?
Green tea memory foam can reduce odor, but cooling often comes from additional gel layers or breathable covers. Not all green tea foams are cooling.
How long does the off-gassing smell last?
Owners report that the initial chemical smell dissipates within 2-5 days. Green tea foam may reduce the intensity compared to standard memory foam.
Can I use a box spring with these mattresses?
Yes, but a slatted bed frame or platform base is recommended for proper support. Box springs with weak slats may void the warranty.
