I bought four of these and use them both at the tall kitchen counter and then lower at the dinette table.  They are super easy to adjust and put together.  They are attractive and comfortable.  I have received many compliments on these.  The kids and adults love them.

Pros: Attractive.  They look expensive and they were easy to assemble.
Cons: Probably wouldn't be terribly comfortable for someone over 200 lbs.
