Final answer:
The height of the combined frame and mattress in traditional or antique beds varied depending on the style and period.
Step-by-step explanation:
In traditional or antique beds, the height of the combined frame and mattress varied depending on the specific style and period. For example, during the Victorian era in the late 19th century, beds were often high off the ground with tall bedposts, elaborate headboards, and thick mattresses. On the other hand, in the 18th century, beds were generally lower to the ground with simpler designs and thinner mattresses.
