Description

The present invention relates to a sauna mat. More specifically, the present invention relates to a sauna mat that is convenient to carry and can be used comfortably in a sauna.

In recent years, saunas have become popular with many people because of their systemic blood circulation promoting and mood-changing effects. The saunas provided in bathhouses and sports clubs are equipped with wooden benches so that many people can use them. Since many people take turns using such saunas, there is a tendency for traces of sitting on the bench with bare skin to remain. For this reason, towels are provided in the sauna for the user to lay on the seating surface of the bench. By laying a towel, the user can sit on the bench without directly touching the sitting marks of others. However, towels have good water absorption, and if they absorb more than a predetermined amount of sweat, they tend to be soaked in water. For this reason, towels are not always comfortable to use for users who use the sauna for a long time.

In order to deal with such problems, there is a water mat technology that can be used in bathhouses, sauna facilities, etc., and can reduce the labor and cost required for washing and drying while ensuring excellent water absorption and a good feel. It is known (see, for example, Patent Document 1). Further, there is known a technique of an underlay sheet for a sauna mat that makes it easy to maintain a comfortable sitting comfort for a sauna user without increasing the maintenance cost (see, for example, Patent Document 2).

However, the water mat shown in Patent Document 1 and the underlay sheet for a sauna mat shown in Patent Document 2 have problems that they have a complicated structure, are troublesome to manufacture, and are inconvenient to carry.
