Set of two razorback armchairs

Set of two brutalist razorback easy chairs
these easy chairs were made in belgium in the 80s. They have the typical brutalist shape from those years. They are in very nice and solid condition with a new upholstery. These chairs are very reminiscent of the chairs of Guillerme & Chambron.
 
This style of chairs is called a "Razorback" dining chair
