This is a very nice find Dutch vintage design! The famous model by Friso Kramer is named “Result”. This is one of his most iconic designs that has won many design awards for the smooth, practical design without unneccessary details and showing beauty in simplicity. They were commonly used in the Netherlands as school chairs in the 1960s and have evolved into a modern day must-have for any design enthusiast! The chair is made of blue wood on a black metal frame, creating a nice harmonious and industrial style. It remains in very good, vintage condition.
