Water bed is a flexible bed, which is not suitable for minors, while electric bed is an ordinary bed with a set of electric mechanism, which is convenient to use; These are two different kinds of bedding, which are completely determined by personal preferences and tastes, but from the perspective of fitness, waterbeds are not suitable for long-term use. Of course, we can't generalize. A few elderly people especially rely on soft beds. A slightly harder bed will make the bones of the whole body uncomfortable, especially the cervical and lumbar vertebrae, which will make them unable to sleep well for a long time. At this time, the waterbed is a better choice.
