Great Stool, Great Price.
NRG® Rolling Stool W/ Removable Backrest Agate Blue
I was in love with this stool as soon as I sat in it. It was much more affordable than other stools that look the same. Within 48 hours I was ordering a second one for my wife. It keeps you in good posture and it's well made. I will most definitely buy more of these in the future.
