Bernhardt Design | Introducing the Astra lounge chair designed by Cory Grosser. Blending precise geometric details with a curved silhouette, Astra is visually striking from all angles, making it an adept solution for the social atmosphere of today’s open-plan environments. The strength of Astra’s design rests in the subtlety of its form, which is accentuated with a welt detail outlining the edges and back of the chair.
