I'm getting a custom ottoman made and asked about getting it upholstered with an aniline steerhide. Their leather dealer also dropped off bullhide samples. I didn't think there would be a difference, but they say it's even thicker than steerhide?

Is this true? And do I have any reason to avoid bullhide for an ottoman?

I'm told I'll need one hide. I have no idea what the price range would be for an aniline steer or bull hide.
