A: The traditional mattress was introduced by Mr. Simmons of the United States in 1876, and it has been 148 years now. Because Mr. Simmons did not apply for a patent, it has brought about a subversive change in the world's sleep products, but the product structure did not change before 2015. The main structure is steel springs plus various comfort layer fabrics, including the familiar sponges, latex, 3D, and various cotton, linen, woven, and knitted fabrics. Therefore, the price difference between different brands is mainly the difference in the support layer, comfort layer, or fabric. Our smart mattress mainly changes the core support structure of the steel spring to intelligent suspension adjustment technology, and uses technologies such as sensors and ESA dual algorithms. That is to say, we will use the comfort layers and fabrics used in traditional mattresses, and we have introduced the world's advanced bedding production materials and technologies. The comfort layers of the whole series are made of high-quality "healthy, environmentally friendly, comfortable, breathable, soft and pressure-relieving" performance materials in the industry, which are necessary conditions for creating high-quality products. We also focus on the research of sleep feeling to better help deep sleep. You can lie down and experience it.

A: For electronic products, the national regulations are 1 year, and Dsleep guarantees three years. The store can extend it to five years according to the actual situation. After five years, if the use frequency is high, it is recommended to replace it for safety and hygiene reasons. The normal service life of mattresses in developed countries such as Europe and America is 3-5 years, and the industry standard for mattresses in domestic hotels is also 3-5 years of normal use. The actual service life can reach 10 years, just like our home appliances.

A: The product has passed the testing of the national designated third-party organization. The input voltage of the product is 24 volts, which is completely a safe voltage, and the safety is higher than that of our mobile phones and electric vehicles (without built-in batteries).

A:The development time of smart mattresses in China is actually only three to five years, and it is currently in the initial stage of development in China. There are only a few enterprises that can do a good job in smart mattresses in China.

Our Chairman Cao Zeyun founded Goodnight Home in 1986, pioneering a legacy of uncompromising quality. In 1992, his iconic tank pressure test – literally driving a military tank over mattresses to demonstrate durability – catapulted the brand to industry fame, earning the moniker “The Forged Standard of Excellence”. This relentless pursuit of engineering perfection remains encoded in Goodnight's DNA

We usually divide the development of smart mattresses into four stages:

The pre-intelligent stage, mainly by adding mechanical equipment such as hydraulic pumps to the bed frame, so that the mattress can be lifted, and functions such as massage through mechanical vibration, and the control method is generally a remote control.

The first stage of intelligence is that the mattress can carry out rough softness and hardness adjustment or self-adaptive adjustment, and some can calculate heart rate, breathing and other data through sensors (not accurate enough), mainly controlled by remote control, without APP.

The second stage of intelligence is that the mattress can accurately adjust adaptively, has a more accurate sleep report, has an APP, can carry out remote diagnosis and upgrade, can continuously optimize the adjustment data, and can carry out passive health intervention.

The third stage of intelligence is that the mattress has become a health management tool, which can optimize data based on the personal situation of each user, and can actively intervene or even warn of health risks.

At present, most enterprises are in the pre-intelligent stage, a few enterprises are in the first stage, and very few enterprises are partially in the second stage. We are currently one of the very few enterprises.

In addition, there are few domestic enterprises that have nearly 40 years of R&D and production experience in traditional mattresses, as well as the understanding of mattresses and sleep. Our boss is also a deputy to the Provincial People's Congress, the president of the Hunan Provincial Home Furnishing Association, the vice president of the China Home Furnishing Association, and one of the drafters of the national mattress standard. There should be not many smart mattress enterprises with such a background. You must have understood this because you are so professional.

A: First of all, I can definitely tell you that we cannot collect your privacy data. The reasons are as follows:

(1) Our boss is a deputy to the Provincial People's Congress, the president of the Hunan Provincial Home Furnishing Association, the vice president of the China Home Furnishing Association, and one of the drafters of the national mattress standard. His name is Cao Zeyun. You can check it on the Internet. Our fixed assets have exceeded one billion yuan, and the annual sales of the group are also more than one billion yuan. Do you think he is willing to ruin his reputation for making this kind of money?

(2) The data processing of our mattress is divided into offline and cloud, that is, the ESA dual algorithm we mentioned. The offline data processing is through the microcomputer embedded in the foot of your mattress. If you are worried about data privacy, you can also choose not to connect the mattress to the network and still use it, but we cannot provide you with the push of healthy sleep modes based on big data and the optimization of new functions. In the later stage, you can also regularly connect to the network to update the data and then disconnect the mattress network again, which will not affect other functions.

(3) Our mattress reads data about once every 3 seconds. With so many customers uploading data at the same time, if I collect all kinds of data, how much storage space do we need? We also need to purchase storage space from Alibaba Cloud, Tencent Cloud, Huawei Cloud, etc. The cost itself is very high, so we cannot want your privacy data from an economic point of view. The uploaded data is processed by your local microcomputer and then selected to upload the data related to sleep.

The most important point is that the state has legislated that the sale and collection of privacy data should bear criminal responsibility. How much money do you think my boss and I can make by selling such a mattress? Do you think we will take such a risk?

At present, there are many types of sleep monitoring devices on the market, including professional equipment in hospitals, smartphone applications, ultrasonic radars, and devices based on air pressure and piezoelectric sensors. These devices collect users' sleep data through different technical means and generate sleep reports through algorithm processing. However, due to factors such as technical principles, use environment, and individual differences, the accuracy of these devices varies to a certain extent.

The devices attached to the body to collect information in hospitals are usually considered to be more accurate because they use professional medical technology and strict monitoring standards. In contrast, other consumer-grade products, such as smartphone applications, wearable devices, and innovative sensing technologies, although they can also provide a certain degree of sleep monitoring functions, their accuracy cannot reach the level of hospital devices due to the limitations of their technical principles and use environments, usually fluctuating around 85%.

Specifically, the accuracy of these consumer-grade products is affected by many factors. First, different devices may use different sensors and algorithms, resulting in differences in data collection and processing methods. Second, each person's sleep environment, sleep position, and other factors may also have an impact on the monitoring results. For example, the softness and hardness of the mattress, the temperature and humidity of the room, etc., may affect the sleep quality, thereby affecting the monitoring results of the device.

Nevertheless, based on the same set of data collection system and basically the same use environment, the sleep reports generated by these devices still have a certain reference value. The advantage of these consumer-grade products is that they can continuously monitor the user's sleep pattern for a long time, helping the user track the change of their sleep status over time. Even if there is a certain error range in the accuracy, as long as the same set of data collection and analysis system is used and the user's sleep environment is relatively stable, these devices can still effectively reflect the trend of improvement or deterioration of sleep quality for individuals. This is very helpful for reminding users to pay attention to the adjustment of living habits, such as regular work and rest, optimizing the sleep environment, etc. If users have serious problems or doubts about sleep, the most scientific approach is still to consult professional medical personnel and carry out professional examinations.
