These stools are cute, and they are comfortable. I would say the metal parts feel and look very delicate.  The cross bar where your foot rests, I fear will get broken quickly. The biggest problem: the directions say, "do not use water to clean", use only a dry cloth to wipe, "dab, do not wipe, if water gets on the chair". As a mom of young kids, I cannot imagine a kitchen situation where this would be reasonable. Maybe a staged house? I have small kids and if wiping a mess up with a wet cloth is going to destroy the finish, these chairs won't last long. So, basically, I feel like I've wasted my money, as I'm assuming I will have to buy new stools with in the year. 
I love the way these look, so if you have an island that gets minimal adult usage, these are great. But if you need something family friendly, I would look for something else.
