Aeromat Adjustable Ball Stool

For those looking for something to help them sit straight, this is da' bomb! Iused standing desks, saddle stools, full sized balls, regular chairs....you get the picture. I have had this a week and my back and hips already feel better. Not only is the ability to spin around convenient to grab something from the printer, it also really makes you engage your seat. For quality, everything is good except the lever and hydraulic for up and down is a bit wonky. I had to manually engage it to get it to rise up the first time.
