Dimensions are appx. 18"D x 17.7"W x 40.2"H. Seat height is 30”. These modern bar stools are amazing - comfortable, easy to clean, stackable. They were kept inside for the short time we had them (decided to re lay out the area they’re in and are taking out the bar, hence getting rid of them). They can certainly be used as outdoor seating as well. Originally $266 per stool, I’m selling $400 for all four.
