To pick a favorite is hard. Morrison, BarberOsgerby, Grcic, Fukasawa and the Bouroullecs have between them designed so many iconic ones.
And that just the contemporary designers.
I got a soft spot for Maruni, Arper and Vitra.
But a chair that I have always liked a lot due to its details is the Colander Chair by Patrick Norguet, manufactured by Kristalia.
I just think its near perfect in construction and proportion.
I saw a Wood seat version in Milan this year which was gorgeous and gave me serious Prouvé vibes.
