Over at a client's on Tuesday, we complimented her on this chair and she said, "Oh, that old thing? it was left here by the previous tenant." We loved it. We asked if she knew who made it. No idea. We took pictures and we looked underneath. Turns out it is an old Knoll piece with cool rubber casters from the Faultless Caster Company, but we have no idea of the name or model. Do you?
