If something is connected to the Internet, it is called “smart.” There are smartphones, smart speakers, and smart watches. Now they are selling smart beds. Some smart beds can track how well you sleep. They make changes to give you a better sleep. For example, they can change the temperature of the mattress so that you can sleep comfortably in any weather. They can also change how the mattress feels. Do you want a soft mattress or a firm one? The position of the mattress is also important. Do you want your head or your legs to be higher? I sleep well anywhere, so I don’t need a smart bed, but I think they can be very helpful for people who don’t sleep well.  (124 words)
