Anticipating another scorching summer, a highly cooling pillow with a Q-max value of 0.429 is now 10% off for a limited time, offering a solution for restless nights.

In recent years, summer heat has been intensifying year by year. According to an announcement by the Japan Weather Association, temperatures in 2026 are also predicted to be higher than average, with the possibility of severe heat particularly after the rainy season. Furthermore, concerns are rising about a decline in "sleep quality" due to restless nights caused by these effects.

Amid increasing interest in nighttime sleep environments due to the intense heat, demand for heat-countermeasure products, such as bedding made from contact cooling materials, is growing.

Against this backdrop, Fuji Bed Kogyo Co., Ltd. is implementing a limited-time 10% off campaign for its cooling pillow, which uses contact cooling material and achieves a Q-max value of 0.429.

Cooling Design Pillow Developed for Restless Nights

◇Cooling Performance

This product is a contact cooling pillow developed with a focus on summer sleep environments. The outer fabric uses a contact cooling material, providing a cool sensation upon touch. Furthermore, in terms of "Q-max value" (a numerical value indicating the amount of heat transferred when touching the skin), which is one of the indicators of cooling performance, this product achieves a high value of 0.429. (Generally, a value of 0.2 or higher is said to start feeling cool, and the cooling sensation increases with higher values)
