■ [CAUTION!] Does "Catching Up" on Sleep During Holidays Lower Performance After the Break!?
"Even after a long holiday, why do I still feel sluggish...?" Have you ever had such an experience? In fact, this is not just your imagination or laziness; it might be due to social jet lag. Social jet lag is a phenomenon where the body's internal clock is disrupted by the shift in wake-up times between weekdays and holidays, and it is gaining attention in the field of sleep research. It is especially prone to occur after major holidays such as Golden Week. On the official Koala blog, we provide an easy-to-understand explanation of measures and tips to prevent social jet lag and comfortably welcome the post-GW period.

■ About Koala®︎
"Slepa" is important for sleep-deprived Japanese people!
Japan has the shortest sleep duration among the 33 OECD member countries*. Sleep deprivation leads to a decrease in daily performance. In 2015, Koala was founded in Australia as a D2C (Direct-to-Consumer) bedding and furniture brand. Since its expansion to Japan in 2017, based on thorough research, it has continued to develop mattresses that enhance "Slepa" (sleep performance = quality of sleep).
Thanks to these efforts, in September 2024, the "Original Koala Mattress" won first place in both "recommended high-resilience mattresses" and "recommended low-resilience mattresses" rankings by mybest, a product comparison service. In October of the same year, "Koala Mattress® PLUS" and "Koala Mattress® SUPREME" were launched, based on the know-how of previous models. Furthermore, in November 2025, the "Original Koala Mattress" received the "mybest AWARD 2025" Best Award in the bedding category. All these products feature simple and sophisticated designs inspired by the beautiful nature of Australia.
Furthermore, under the corporate goal of "creating a healthier and happier living environment," Koala has donated over 1.5 million AUD to the World Wide Fund for Nature (WWF), contributing to the protection of endangered species such as koalas. In Japan, these efforts also support the protection of indigenous species like the Amami rabbit and Miyako snake lizard found in the Nansei Islands.
