Conventional medicine is the type of medicine that the people who control the medical education system have deemed to be the most appropriate system of medical care. In the United States, conventional medicine consists primarily of drugs and surgery, which are the most widely used treatment modalities.
There are common established heights for table/counter surface and seating combinations. They are: Table height: 30in (750mm), with a chair at 18in (450mm). Counter height: 36in (900mm), with stools at 24 in (600mm). Standard bar height: 42in (1050mm), stools at 30in (750mm).
These stools are designed to be used at a counter height of 36 - 39. 30 inch stools are designed for bar counters that are 40 - 45 in height. This stool size is also suitable when being used in a family room around a pool table or shuffle board. 34 inch stools are a custom size stool. Most people would not need this height in a barstool.
