What type of stool should I use with a sit-stand desk in the standing position?

Active stool specification for sit-stand desks at OfficeFurniture2go.com: height range 22–32 inches, forward tilt base design (Balans-style or saddle), adequate seat width for the user, and commercial-duty weight rating. We specify active stools as the second seating component in complete three-posture workstations. The stool enables productive semi-standing use and extends total standing tolerance through the day. Call 1-800-460-0858 for complete workstation specification.
