WTB: Drafting chair

[speedog]

Need to replace a drafting chair that we have and thought I'd look to Beyond to see if anyone has one that's sitting idle/collecting dust. Seat height needs to go up to at least 33-34", no armrests preferred and a non-fabric seat/backrest would be preferred as well. See pic below for an idea of what I'm looking for - please PM me if you have one or if you know where I might be able to get such a thing locally in Calgary.
