Sleep research studies demonstrate that heat build-up and perspiration in bed significantly reduce sleep quality. With Aerelle® Cool Night, ADVANSA has developed a high-performance fibre concept for duvets and pillows that quickly, effectively and continuously dissipates excess body heat – ensuring a consistently comfortable sleep environment.

The high-tech cooling fibre Aerelle® Cool Night is based on a special Cool-Flow-Crimp Technology (CFCT). This structure enables constant heat dissipation from the body throughout the night, creating a noticeable cooling effect.

Scientifically Proven

The effectiveness of Aerelle® Cool Night has been systematically examined and confirmed by independent German and European testing institutes. Physiological measurements confirmed that pillows filled with Aerelle® Cool Night achieve:

In addition to its cooling effect, the advanced crimping technology ensures lightness and a soft, cosy touch. The lower temperatures and increased cooling capacity of Aerelle® Cool Night generate significant thermophysiological benefits for the body, providing ideal conditions for restful sleep.

8-Hour Freshness Factor

Test results demonstrate that the cooling effect remains effective over a full sleep cycle of up to 8 hours. This corresponds with the average sleep duration of 6–8 hours, as determined in a study conducted by the Institute for Marketing Consulting at TU Dortmund.

High level of consumer demand

A dedicated concept test within this research project for ADVANSA also revealed high consumer interest in Aerelle® Cool Night:

Conclusion

Aerelle® Cool Night offers bedding manufacturers a differentiating performance feature: a scientifically proven cooling fibre solution that combines comfort with functionality and enjoys strong consumer acceptance. The concept is suitable for year-round use – reducing heat accumulation making it easier to fall asleep, stay asleep, and enabling a refreshed awakening.
