TENTIAL Unveils the BAKUNE Cool Comforter for Summer Sleep

As the summer heat intensifies, achieving proper sleep has become a challenge for many. TENTIAL, a company committed to creating a society focused on health and well-being, recognizes this issue and has introduced a unique solution: the BAKUNE Cool Comforter. On June 13, the brand commenced airing a television commercial across the Kanto and Kansai regions of Japan, tackling one of the most pressing summer sleep challenges: balancing the effects of air conditioning.

Founded in Shinagawa, Tokyo, TENTIAL operates under the mission of promoting a health-conscious society, thus releasing the potential of humanity. The brand believes that not only inherent abilities but also optimal physical conditions significantly contribute to unlocking one's potential. However, the notion of maintaining adequate condition is often seen as specialized or difficult to achieve. To combat this, TENTIAL aims to reimagine everyday life through a conditioning lens and make enhancing well-being the norm through scientifically-backed products.

The significant impact of temperature and humidity in sleeping environments can considerably alter sleep quality. With the increasing trend of utilizing air conditioning during hot nights, many individuals report difficulty in achieving optimal sleep. According to a survey on summer sleeping conditions conducted by TENTIAL in May 2026, 46.3% of respondents who sleep with air conditioning noted that they felt excessively cold, while 53.7% experienced disruptions due to heat or humidity.

In response to these challenges, TENTIAL has devoted its efforts to supporting sleep conditioning through various products, particularly its line of BAKUNE recovery wear. Recognizing the need to go beyond apparel, TENTIAL developed the BAKUNE Cool Comforter as a tool to enhance sleep conditions. Utilizing its proprietary Sleep Conditioning Technology®, this comforter efficiently maintains ideal temperature and humidity levels by evacuating heat and moisture when it’s hot and retaining warmth when it's cold. Thus, it aims to facilitate restful sleep without the negative impacts of over-cooling or humidity that typically accompany air-conditioned environments.

Since its launch, the BAKUNE Cool Comforter has garnered high customer satisfaction and recently demonstrated sales growth that surpassed recovery wear, marking it as a leading product in TENTIAL’s sleep category.

TV Commercial Overview

The recent TV commercial produced by TENTIAL highlights the dilemma of summer sleep: the discomfort of feeling too cold with air conditioning while also being too hot without it. By showcasing contrasting room temperatures of 23℃ and 31℃, the commercial effectively portrays the various challenges faced during summer sleeping conditions. Furthermore, it illustrates how the features of Sleep Conditioning Technology® significantly improve comfort, leading to refreshing mornings even in the hottest summer nights.
