In traditional or rustic interiors, however, the accent is not as much on the sophisticated looks as it is on the way an element matches everything else around it and on the way it integrates in the whole décor composition.
You should also measure the space between the seat of the stool and the underside of the counter. A 9” to 12” space is a good choice. This means you and your guests would be able to sit comfortably without touching the counter with your knees. But measurements aren’t everything. You also need to think about the style of your counter-height bar stools, the materials they’re made of, their color and their number.
Another good example of simple design that fit in a variety of interior designs is that featured by Stool_One by Magis. Here you can see it displayed in a contemporary setting where it complements a large kitchen island.
The general opinion is that bar stools with backs are more comfortable than the backless ones. It’s quite logical actually. Having something to rest against is definitely comfortable and even ergonomic, especially if you’re sitting on the stool for long periods of time. Backless stools can be comfortable too, usually if they’re only used periodically or for short periods of time.
