European furniture brand Riluc offers, well, insane objet d'art furniture primarily out of steel; if you're a production designer on a Bond film tasked with creating the antagonist's lair, this here is one-stop shopping. The bulk of the pieces are designed by company founder and Portugal-based French expat Toni Grilo, whose website states he is "obsessed by the beauty of technical processes and materials."
"The strong presence of her simultaneously elegant and daring curves make this chair a recognisable luxury icon. The chair became a sculpture! In an amazingly bright stainless steel or with titanium coating for a gold or copper version."
"Take time to immerse yourself in this marvelous madness. Toni Grilo dares with an unconventional, powerful approach on the creation of this masterpiece. Go MAD in this armchair, it disturbs and excites. Soft leather on hard, mirror polished stainless steel."
