I found the perfect preowned bar stool for you. It is model 20-6 by Emeco.
The ergonomically shaped alumninum seat are hand welded, resulting in a minimal, seamless appearance. 20-06 is super strong, yet uses 15% less aluminum than the original Navy chair. Of that metal, 80% is recycled aluminum, qualifying it as an environmentally sound product.
The lightweight aluminum frame is as sleek as it is nice. I like the design as a stand alone side table or bar stool.
Dimensions: 35,5 x 35,5 x 77 cm
Flaws: Scratching to the aluminum on several spots.
