One major trend from Paris and Cologne: stronger presence of wood

This is not a new trend - it was there last year, too, but

"now the innumerable tree stumps have become more bulky and the whole thing comes across as being ostentatiously in too close touch with nature"as from Stylepark describes it. And I agree to a great extent - overdoing the positive pursuit of sustainability and re-use of wood will alienate many people from the idea. On the other hand, I like the sophisticated and relaxed style of Gervasoni (above).
Some more examples:

Briccole Venezia, the design forms part of a larger project for Milan furniture company RIVA 1920 where 18 designers and architects have been asked to design products using recliamed oak from Venice’s waterways mooring posts substituted from the Venice’s lagoon because of wear and tear or breaking.

Base stools, design: Lukas Redwitz, made of oiled natural oak

Similar, but much more artistic are the cocktail tables from Suzanne Rippe's Bloc collection launched last week at Maison & Objet in Paris and this is an approach I strongly approve.
Examples of such approach there has been a lot at IMM Cologne, too, and I will quote again Thomas Wagner:

"In general in Cologne hand-made goods and arts and crafts would appear to be surfacing again. It is indeed amazing how quickly the void left behind in Cologne by absent designer manufacturers has been filled by handicraft beginnings or, in other words, the term design has been loosened from its industrial anchoring."
