The rainy season when it is difficult to dry the futon due to heavy rain. Even so, I'm worried that my night sweats will be covered well and that I won't get moldy.
In such a case, we recommend the "good sleep dehumidifying sheet for mattresses". A sheet that absorbs the odor of moisture and sweat when laid under a mattress. Obtained at Rakuten Ichiba for about 1,000 yen (tax included and shipping not included).
A mechanism like a myriad of small silica gel packs connected together. It doesn't look good, but it can absorb about 400ml (13.53us fl oz) of water as a whole.
The size is about 98 x 102 cm, almost square. It is recommended to lay it around your back where you can easily sweat. If it is a mattress of a general thickness, you will hardly feel any unevenness.
This size for a single mattress (actually laid under the mattress)
When the color of the reproduction signal attached to the corner changes, dry it in the sun. It can be used repeatedly about one year after opening. Unlike the mattress itself, you can go out while it is dry, and the point is that it can be dried in the bathroom or indoors.
I want the futon that collapses at the end of the day to be as comfortable as possible. How about incorporating it for the coming season when the humidity is high?
