Kaisuin (Quick Sleep) Double Size

Used a few times and then stored at home.
This listing includes the device and its dedicated mat. (The dedicated mat is a double size.)

The following is quoted from the store's product page:

Kaisuin is an eco-sheet (hot water mat) with a hot and cold water circulation system that circulates water throughout the sheet to maintain a comfortable temperature. In winter, it provides cozy warmth with the hot water mode, and in summer, it offers a cool sensation with the cold water mode, creating a comfortable space all year round, both winter and summer.

In hot water mode, you can adjust the temperature from 25℃ to 60℃, allowing you to freely set a comfortable temperature tailored to the user.

In cold water mode, the sheet cools down to an average of around 20℃. After that, it gradually returns to room temperature as the ice in the cooling bottle melts.
