Polymorph is a cast aluminum lounge chair by Objects of Common Interest, the Brooklyn and Athens-based studio founded by Eleni Petaloti and Leonidas Trampoukis. The chair is constructed from aluminum and finished in transparent glossy paint, the clear coat preserving the material's own surface rather than adding color or concealment.

The form arrives through a process the studio describes as documenting and translating: taking natural reference points and converting them into a cast aluminum seat. The result sits between artifact and furniture, a solid object whose form carries the trace of something observed rather than something invented at a desk. The transparent paint reinforces this reading, keeping the aluminum visible beneath the finish rather than replacing its surface with something else.

Polymorph sits within Objects of Common Interest's consistent interest in materiality and the relationship between natural and manufactured things. The studio works extensively in resin and cast materials through their Piraeus fabrication workshop, and the Polymorph applies that sensibility to seating, producing a chair that reads as both a functional object and a condensed material study.
