Multiple Armchair is a minimalist armchair created by Seoul-based designer Seungyeon Shim. The Multiple Collection is a collection of a steel chair, stool, and bench that combines multiple metalworking techniques. The collection is made from a combination of steel plates and round pipes. In particular, it is realized through techniques such as sheet metal bending and pipe pressing. This combination of materials and techniques makes it possible to reach great quality, and all seating can have its own characteristics well suited to the surroundings. This collection is powder coated and can be used in any space. Recently, armchair and seat cushions have been added to the collection for extra comfort.
