Once you got all measurements right, you need to decide how many stools you need. Figuring out the number is easy. You need to provide adequate spacing for people to eat, drink or socialize. A distance of around 26”-30” between the centers of the bar stools should be ideal.
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.
Green Gables Furniture has this Steel Traditions Crestone Swivel Barstool that features leather seat. Lapped seams across the cushion add strength and the old-fashioned steel base has a characteristic round foot rail. A little color goes a long way in enhancing the wood of these rustic bar stools. Perfect for a rustic, industrial or casual living space, these seats from Horizon Home have a subtle streak of green that adds a reclaimed feel to the pieces.
If your bar stool area is nearby other chairs, you might consider coordinating the seating throughout the space. This isn’t to say you should run out to the nearest furniture store and buy a set of identical-except-for-height chairs and stools. But you could consider keeping one style element similar for consistency, such as the wicker seats in this photo.
