Herman Miller Aeron Work Stool. Bought for stand up table usage but never got around to getting the table. Never used for work, but it’s a few years old so I can’t sell it for brand new. But, in theory it is since it’s never been used in a work environment. I have the regular Aeron chair and know nothing beats it for comfort and back relief. Aeron work stool revolutionized office seating with its defining design qualities: the pioneering Pellicle suspension material and its patented PostureFit SL back support, which affords the ideal sit: chest open, shoulders back, pelvis tilted slightly forward. Combining a deep knowledge of human-centered design with cutting-edge technology, the Aeron counter-height stool is engineered with state-of-the-art adjustability, from the arms, seat height, depth, and recline.
