About UsAbout Us
Invest 30 minutes, twice a day, for an energetic day!

William Shakespeare quoted ““O sleep! O gentle sleep! Nature’s soft nurse”.
We all know that good night’s sleep is the simplest and the most powerful way to secure health and it is also very important to stay healthy.

Sleep is not just a form of resting, but is a process of restoring the fatigued body and mind for the normal activity on the next day.
LEESOL has been developing and producing wellness products and wearable device called ‘sleepisol’ with a wide-spectrum workforce since 2017, and are expanding in the field of medical devices.
We aim to increase the quality of life and secure healthy living by providing good quality sleep to the modern people who overlook the importance and value of ‘sleep’, which makes up one third of their lives.
