I absolutely love these counter stools. They are the perfect height, and my 2 year old enjoys sitting on them to eat her fries. 
I was worried they would be a bit short, but they are not. You do have to sit a bit forward when sitting on them so the edges of the stool doesnt knead into your thighs, but thats an adjustment thats easy to make once you get used to the shape of the stools. And thats another point, I love the shape of the stools and it fits the cozy midcentury modern vibe Im going for.
They are solid wood, so they come in different variations and also slightly different heights, which I didnt mind. I just rearranged them with the tallest one in the middle and the shorter ones on either sides and it makes it not as visible to the eye.
