Engineering Temperature Regulation the Right Way
I have been building mattresses for more than forty years. When you work with materials that long you learn something important. Cooling is not an add on. It is not a surface treatment. It is not a chemical designed to feel cold for a moment and then trap heat by dawn.
Cooling is physiology.
If the body cannot shed heat consistently, it will not stay in deep sleep.
Many mattresses today rely on cooling gels, chemical coatings, or “ice touch” fabrics that feel cool at first. The problem is simple. Those treatments absorb heat, then hold it. Within a few hours the mattress becomes warmer than the body and sleep becomes shallow and restless.
Cooling does not matter at bedtime.
It matters at two in the morning when the body needs to stay in deep rest.
True Cooling Comes From Architecture, Not Tricks
Real temperature regulation requires airflow, responsiveness, and materials that move energy rather than storing it. A mattress cannot earn the word cooling because of one layer. It must release heat as a system.
At Tiami every layer contributes to that. Together they work quietly to maintain a stable sleep temperature all night long.
The coil support system
Coils create open space inside the mattress. Air moves freely instead of being trapped in dense foam. When you move, air circulates through the mattress and pulls heat away from the body.
The Energex comfort layer
Traditional memory foam traps heat and holds you in place. Energex does the opposite. It has an open cell structure that allows airflow and responds to heat with gentle pushback, so movement feels effortless. You do not melt into it. You float on it. That keeps heat from pooling under the body and stops that stuck, warm feeling.
The precision cut performance layers
We fuse the Energex layer to a high density recovery foam layer, then cut air channels through the combined system. Heat rises through those channels and dissipates instead of concentrating. You get true contouring without the thermal penalty.
The natural cotton cover
Our cover is made from naturally breathable organic cotton, not coated synthetics. It lets the airflow reach the surface and release. Nature has always been better at temperature balance than chemistry alone.
Cooling is not what happens in the first five minutes.
Cooling is what continues quietly for eight hours.
Why This Matters
The body lowers its core temperature to enter and stay in deep sleep. If the mattress traps heat, the body wakes to protect itself. You may not remember waking. But you feel it in the morning as fatigue, heaviness, or the sense that sleep happened without restoration.
You do not need to sleep cold.
You need to sleep regulated.
A truly cool mattress does not pull heat toward you or hold it below you. It moves it away from the body and releases it.
Modern Luxury Is Reliable Comfort
Classic luxury mattresses often rely on thick comfort layers and dense padding. They feel plush, but over time they run warm and lose support. Luxury should not fade. It should perform over years, not nights.
We designed Tiami to do that. Breathability. Responsiveness. Stability. A mattress that holds your body in alignment and stays cool without gimmicks or tricks. One that performs in the middle of the night, not just the moment you lie down.
Temperature control is not a feature.
It is part of health.
And luxury should honor that quietly, consistently, every night.
