I bought this for our kitchen island and it fits well and looks good.  Seems sturdy with a base wide enough to keep it balanced, but not so wide that it takes up too much room.   It has already been spun, raised and enjoyed by our young son, as well as being a comfortable perch for meal preparation or a meal.  The only negative is that it takes more weight than mine to lower it after it has been raised, but that may also be a plus in that it will not sink unexpectedly!

Pros: Attractive, easy to assemble...and fun!
Cons: The base is a little light, but if no one is spinning until they are dizzy, this shouldn't be a problem!
