Very soft and comfortable.  Feels sturdy, even for people over 200 lbs.  Does not tip over.  Swivels easily.  Nice item.  Everyone loves it.  

Only (mild) complaint is that if you are sitting on it , the ring beneath is not designed where you can put your feet on it easily.  Some people like to do that.

Pros: Soft, comfortable, swivels easily, sturdy
Cons: Difficult to sit on and put your feet on the ring (not a big deal)
