Safco AlphaBetter Adjustable-Height Student Stool, Backless, Supports Up to 250 lb, 35.5" Seat Height, Black

This stool is a perfect substitute for standing. The stools adjust in 1 1/4" increments. The stool allows students to sit and still use the patented Swinging Pendulum™ Footrest Bar (fidget bar). The specially designed wide-angle base of the stool is virtually tip-resistant, even for the most avid learners. Metal swivel glides makes the stool easy to move across carpeted and smooth surfaces to easily reconfigure the classroom.
