Ambassad is an armchair designed by Mats Theselius in 1999 for Källemo. The chair's frame is made of steel and is available in a variety of finishes. Ambassad is upholstered in a faux core leather from Tisnsjö Garveri and is available in a variety of colors. The seat cushion is upholstered with rigid foam.

Mats originally designed this armchair for the Swedish Embassy in Berlin and its popularity has since earned it a permanent place in Källemo's collection.
