Loved it but had to return it within two days because it broke!
This saddle stool was awesome for about 48 hours.  I knew there would be some breaking-in time, so I didn't push it.  The third time I sat on it, I was showing my husband how easily adjustable heightwise it was.  I lifted the lever to adjust the seat and all the hydraulic up/down function quit working.  The chair was then stuck in the lowest position possible.  I was unable to get it apart and had to return it in a larger box.  I'm bummed, because I wanted to like this chair!  Now I'm looking into a dental saddle stool which is made more durable!
