What does a waterbed room mean?

Waterbed room refers to a room in a hotel. There is a special waterbed in the room, so it is called waterbed room. This kind of room is more expensive than ordinary rooms. Water beds can make people's backs feel extremely comfortable. Lying on a floating mattress, the water will automatically drain according to their body shape. The bed will not sink and deform (even after 10 years). Regardless of the weight, it will automatically adjust quickly to support the whole body.
