In winter, in the north, people use radiators to keep warm, while in the developed areas of the south, air conditioners are used to ward off the cold. In some places, all that is needed is an electric blanket, which is relatively cheaper than radiators and air conditioners. For areas using electric blankets, a better heating product can be recommended - the smart warming mattress. Compared to electric blankets, it is much more soft and comfortable. But what makes it even more advanced is its intelligence. It can automatically maintain a constant temperature of 76.4°F, making you feel extremely comfortable. Of course, you can also adjust the temperature according to your needs. Moreover, after being used for 10 hours, it will automatically turn off. Although there are wires built inside, they are hardly noticeable. And it uses the best voltage material, with a high safety factor, allowing you to sleep soundly and comfortably throughout the entire winter. However, the price is currently not affordable for the average person. Depending on the model, prices range from over 3000 yuan to nearly 5000 yuan.
