We have several ideas as to how we will use this stool.....one is as a task chair for my son's photo shoot area.  He can roll around the subject while continuously snapping pictures.  It also tucks nicely under a small desk where I can write bills.  

Pros: Good weight and quality rollers that glide well.
Cons: While the seat is firm and sized well, it is a tad hard.......but better that than too soft.
