ergonomic work from home stool - $45 (berkeley)

Autonomous ergostool for active posture while working at desk.
Excellent condition.
25inches at shortest and 35inches at tallest.
I changed desks and this stool no longer fits my needs.
Pretty darn expensive new and this is in excellent condition I just need it gone.
