Recently, many summer beddings have been developed to help you sleep comfortably without relying too much on air conditioners, so you want to make good use of them. We often see cool contact materials and gels, but Vega Corporation, which operates the mail-order site "Furniture Mail Order Roya," sells the latest model of the cooling mat "SALTY COOLER," which is neither of them.
The original material "Ice Salt" developed by the company focusing on the "power of salt" that cools ice to below freezing is used in SALTY COOLER. It liquefies at about 30 to 31 degrees Celsius, which is close to the surface temperature of the skin, and keeps the room temperature while repeating heat absorption and heat dissipation (crystal to water solubilization).
The editorial department who was interested got a multi-size for the purchaser privilege this time. I actually experienced the effect.
When you press the mat with your finger, it feels like a hard gel. Stroking the surface makes it silky, but it's not particularly cold.
However, when you press the palm of your hand, the mat becomes softer and sinks slowly, and at the same time you can feel the coolness of the mat! When you lay it on a pillow and lie down, the nape of the neck and the back of the head feel as if you are wearing an ice pillow.
I have sheets made of cool contact material, and although it feels smooth to the touch, after a while it inevitably warms up to my body temperature and makes me feel hot. But this sheet keeps you cool as long as you touch it. Considering that tropical night, which is hard to sleep and turns over many times, I think this coldness is quite comfortable. However, the coldness of the author (female) feels quite cold, so it seems that the period of use will be limited to midsummer. You may adjust it by laying towels or sheets.
In addition, it can be used for sofas and pets as a cooling sheet not only at bedtime but also during hot days, so it seems convenient to have one.
There are two types of SALTY COOLER lineup, S (80 x 90 cm, 4,990 yen) and M (80 x 140 cm, 5,990 yen) (both including tax). There are five color variations, navy, turquoise, brown, border navy, and camouflage navy. You can purchase it at Roya's online shopping site.
