To have a comfortable bar stools, the space that goes from the bar to the seat must be at least 25 cm. For example, the height of a 90 cm bar stool should be around 65 cm. In the case of the relationship between table and dining room chair, that space of separation does not usually exceed 30 cm, but since the posture on the stool is more upright, that space between the two elements can slightly exceed 30 cm.
Therefore, to find the ideal model there are two options: measure the height of the bar or table and based on it choose comfortable bar stools. Therefore, it is normal that we can find different models with measures of bar stool of a height and measures of kitchen stool with another height different. There is also the option of opting for one that is adjustable in height, as is the case of the Hugo model.
On the other hand, stool height is usually preferred in comfortable bar stools. In this case, the measurements of a kitchen stool are usually around 75 cm and even less, in order to have a more comfortable and collected posture, designed to spend more time in it. Wood is a very welcome material, like the Miranda model, although you can also use other options in metal with resistant plastic parts.
