Lifeform 8594 Office Chair Demo. Handmade in Canada. Link to manufacturer product specs: https://www.lifeformchairs.com/contour-task-8594/ This model does not have arms, but could be ordered. We changed the gas lift about a year ago so it's in new condition and has a max height of 24" which is good for taller people but is also adjustable lower. Pick up at 774 Spruce Ave, Tues-Sat 11-3pm
