At just 25 years old, Thomas Barger finds himself wrestling with the ordinary — the idea that he’ll soon be kicked off his parents’ health insurance when he turns 26 — and the extraordinary — raising a solo show of sculptural furniture, on view through March 31 at Salon 94 Design. A recent nod from Architectural Digest and a sale to prominent art dealer and collector Javier Peres also signal Barger’s ascendency into the artistic stratosphere. But while all of these realities point to his newfound adulthood, the works on display at the gallery look backwards to the underpinnings of a youth spent growing up gay on a farm in Mattoon, Illinois.
