I've had these for 1 week and so far I really love them!  I have a small counter and not much room for the stools underneath but decided to try these.  They are perfect.  I didn't know if I would like the small part on the back, but it actually adds support so I'm so happy I decided on these instead of just stools without a back at all.  They are actually very comfortable and I love the how they swivel in addition to adjusting up or down.  We sit on them everyday so I really hope they last.
