I like this interesting task chair from Korean manufacturer IOS Innovator's System. The pads have a molded fabric covered profile which is interesting. There is not a tremendous amount of description on the site, but I am going to infer that this allows the back to be flexible and the molding will actually promote a degree of ventilation. But the one of the best things about their site is all the cool desks they show in their gallery. The desks are not listed as their product so I'm not sure where they are coming from, but I like them!
