The design stipulates the leather--not the other way around.
Anyway, the vast majority of Poltrona Frau leather will be coated. Spinneybeck as well. The ethos of the Italian and American manufacturers that partner with those suppliers reflect that. In contrast, you can pretty much assume non-coated leather will always be an option for designs made by Danish manufacturers.
I suppose it is strange to pick the leather first but it's a piece for my home office so I want it to feel indulgent and leathers with a strong grain don't give me the feeling I want.
I looked at pieces from Walter Knoll, Wittmann, and Linge Roset and I was surprised that they didn't offer the sort of leather I wanted. Brands that I know that offer this leather sort of leather would be Flexform, Baxter (Italy), De Sede, Poltrona Frau.
The Walter Knoll leathers I received are full-grain full-aniline leathers non-pigmented leathers. When you talk about the design that stipulates the leather it really has to do with the construction of the piece and the thickness and durability/elasticity of the leather...you aren't going to wrap a down cushion in 5mm saddle leather and you wouldn't normally use a soft 1.1mm leather for something that requires a rigid structure from the leather. I agree that not all leathers are suitable for all pieces but the leathers that I am looking at should for the most part be interchangeable since their are near the same thickness with similar flexibility.
