Leather Rolling Chair
We've had multiple versions and colors of this chair in our live/work studios for the past 10 years and they're still going strong.
Our favorite (and most resilient) by far is this leather version which also features aluminum legs, although we have the black 3d mesh fabric on the backs of ours which keeps the look a little lighter weight.
We have the counter-height version (which you can tell by the footrest). We always make our desks counter height so that it's more comfortable to collaborate when 1 person is sitting and 1 person is standing.
The link above is for a ready-to-ship version, but you can also build your own from multiple fabrics and with/without various features like armrests (pretty critical in our opinion), lumbar support, headrest, etc. directly from Steelcase with around a 2-month lead time.
