It depends on how much you're willing to pay for them, but the category is "stools", even though you would think of a bar stool rather than a really tall chair.

They come in "ergonomic" as well--a few of the well known chair manufacturers also make their ergo chairs in stool version, like Steelcase's Leap http://store.steelcase.com/products/leap-stool/ http://store.steelcase.com/products/leap-stool/ I have the chair version of this at work, and I like the adjustable arm rests, but overall find my Herman Miller Embody more comfortable. Personal preference though. See if your employer has a preferred supplier for office furniture, the price you see on the sticker isn't the price you pay (around Christmas time, we get discounts of up to 40% for personal purchases)
