Amsterdam-based designer Tuomas Markunpoika aims for “tedious functionality” in his designs, but to us there is mystery and wonder in the bulbous, colorful slabs of material that compose his furniture. His new series of works is called “Contra Naturam,” or against nature — a mauve bench, a coffee table and chair in grayish and springy greens, and a side table and console in pale yellow and cream. Each looks cut from the earth or plucked from a stage set, at once natural and totally fake.
