Cooling Features
Airflow does most of the work. The coils in a hybrid leave open space for heat to move away from your body, while dense all-foam traps it. A breathable cover, gel or graphite infusions, and phase-change fabrics help at the surface. The single biggest...
Some cooling fades and some lasts. Gel and phase-change materials absorb heat well early on, but can warm up once they reach your body temperature later in the night. Airflow-based cooling - coils, breathable covers, and open-cell foam - keeps working...
Coils and breathable covers genuinely help by moving air and heat. Open-cell and latex foams sleep cooler than dense memory foam. Gel, copper, and graphite spread heat sideways so it feels cooler longer, but they do not actively chill. Phase-change covers...
Cotton sheets breathe well, so the heat is usually coming from the mattress underneath, not the bedding. Dense memory foam and thick pillow-tops cushion you by hugging your body, which closes off airflow and traps body heat against your skin. Cotton ...
A hybrid is usually the best choice. Its coil core leaves open channels for air to circulate and carry heat away, and most pair the coils with a breathable cover. Latex and open-cell foams are the next best. Avoid thick all-foam beds with dense memory...
Yes, to a point. Open-cell memory foam, gel or graphite infusions, and a perforated or breathable cover all help vent heat that solid memory foam would otherwise trap. A foam bed with these features sleeps noticeably cooler than a plain one. It still...
They help, but in a limited way. Gel, copper, and graphite are conductive, so they pull heat away from your body and spread it through the foam, which delays the warm feeling. That means the surface stays comfortable longer before it heats up. They do...
A lot. Even a breathable mattress feels hot under thick fleece sheets, a heavy mattress protector, or in a warm room. Cotton, linen, and bamboo sheets vent heat well, while a waterproof plastic-backed protector traps it. The mattress sets the ceiling...
If you regularly wake up overheated or sweaty, yes. Better airflow and a breathable surface can be the difference between waking up hot and sleeping through. Just match the spending to the benefit: a hybrid with a breathable cover delivers real cooling...
Cooling is personal, and a bed that feels cool in the showroom can sleep differently at home over weeks. National Mattress offers a 365-Night Sleep Trial, so you can sleep on it in your own room with your own bedding. Give any new mattress at least 21...
