About Koala

In a country where sleep deprivation is rampant, Koala is on a mission to improve sleep quality for everyone in Japan. As of 2021, the OECD ranked Japan as having the shortest average sleep duration among its member countries. Koala emerged in 2015 in Australia with a direct-to-consumer model and has since expanded into Japan in 2017, focusing on research-backed mattress development that enhances sleep performance.

The brand has received recognition for its efforts, including winning the top spot in both the high-resilience and low-resilience mattress categories by the comparison service MyBest in September 2024. The following year, Koala mattresses were awarded the Excellence Award in the bedding category at the MyBest AWARD 2025.

Koala is dedicated to environmental preservation, having donated over 1.5 million AUD to the World Wildlife Fund (WWF) to support endangered species like the koala.
