Of course, Reverie’s electric bed series is particularly good. I went to their exhibition area to experience the last time I went to the International Furniture Fair, and it was indeed extraordinary. It seems to have all the functions you mentioned above. In addition, is there any negative ion system that can automatically measure the concentration of negative ions and automatically emit negative ions? It can also play videos, music, etc. through voice control. By the way, their electric beds have a market share of over 50% in the United States. Maybe your friend’s electric bed is also from this brand~
