Disclosure: I favor the type of 2 bar stools I had previously that had arm rests and cushioned seats that I love, but my wife felt the look of the seatback would minimize the look of the countertop and  heavy stools are difficult to reposition
We purchased 5 of these for our countertop bar - we have 4 kids ages 7-11.  We'll keep them for the kids,- since they occupy them the majority of the time  but I have some regret not getting chairs more comfortable for me and guests.

Pros: Look nice, slide under the countertop, not too heavy where its hard to move - good for kids so if they swivel they won't bang the countertop also kid's fee reach the foot rest
Cons: Not as comfortable as what I'm accustom to (I'm 6'0, 195, with 36 in waist) or compared to the average stool.  I thought there would be a little back support from the pics, but there isn't any.
