Airflow through the core
Coil support systems contain open space that can permit airflow compared with a solid foam core.
Comfort materials
Foams vary in density, cell structure and depth. Thick contouring layers can surround more of the body, while more responsive designs may create less close contact.
Cover and bedding
Breathable covers can help, but sheets, protectors and comforters also influence the microclimate around your body.
Aviya's design
Aviya markets a breathable cooling top plus an individually wrapped coil core. Treat those as design features rather than a guarantee that every sleeper will feel cool.
