【Cooling Sheet】 This cooling sheet uses a new cooling material with both contact cooling and sweat-absorbing functions. Compared to general cooling sheets, the cooling sensation is upgraded! Cool, smooth, and comfortable to sleep on! ! The cooling effect is further enhanced when used with air conditioning! Cool down your flushed body after a bath or sunburn with a cold sheet! It's cool and feels good, so you can sleep comfortably even on hot nights. It's also very popular as a summer sleep aid and as a gift! The coolness of contact cooling depends on the room temperature, so if you want to enhance the cooling sensation, we recommend cooling the room with air conditioning before use. (The recommended air conditioner temperature setting is 26-29°C). We also carry other cool bedding products that promote healthy sleep without overusing air conditioning. Use them together for even more coolness! For hot summers, humid nights, and the damp nights of the rainy season! 【Moisture-wicking and Breathable】 By changing the way the fabric is woven, we have been able to improve water absorption. Even on summer nights when you sweat, it won't cling to your skin, and you can sleep comfortably and smoothly until morning. Because of the material's excellent water absorption and breathability, the sheet absorbs plenty of moisture such as sweat, diffuses the trapped moisture, and dries quickly, allowing you to use it comfortably. We use a breathable structure and highly moisture-absorbent materials to quickly absorb and release both heat and moisture. Because you sweat easily in the summer, the filling uses clean, comfortable cotton that repels viruses. In addition to having three functions: anti-mite, antibacterial, and deodorizing, it is also lightweight, breathable, and resistant to sagging. 【Antibacterial, Odor-Resistant, and Anti-Mite】 By applying antibacterial processing to the side fabric, we suppress the growth of bacteria on the fibers by more than 99%. Even after washing, bacteria eat sweat and sebum, and the waste products excreted by those bacteria cause unpleasant odors. By reducing the bacteria that cause those odors, we can solve the odor problem from the root. It is antibacterial and odor-resistant, preventing the growth of bacteria and suppressing odors, keeping it clean at all times. With the excellent antibacterial and odor-resistant effects certified by SEK, it can be used with peace of mind by those with sensitive allergies and small children. 【With Rubber Bands & Washable】 The sheet has reinforced rubber bands on all four corners, so you can securely fix the sheet to the futon. It's also easy to remove and attach when washing, which reduces the burden of housework. You can easily wash it at home and always keep it clean.
