A pair of rocking chairs designed by Takeshi Nii and produced in the 1950s, using a wide range of materials. The upholstery is made of natural leather in black with white stitching. The frame is made of aluminium and the skids are made of solid wood. The armrests are made of plastic in a grey-blue shade. The armchair is equipped with a mechanism that allows it to be folded, when folded the armchair is only 18 cm wide. The history of this chair model is exceptionally rich. The presented rocker is the brother of the famous NY Chair from 1958. During his work, the designer was inspired by the director's chair, its functionality, simplicity, foldability and modern Danish design, which is referred to by the materials used. The project has evolved, changed over the years. The final version of the furniture won many awards and in 1970 it became part of a permanent exhibition at MoMA, a museum of modern art in New York City. The armchairs are preserved in the original and their condition can be described as very good. They have slight abrasions and patina marks on the metal, which should not be surprising due to their age.
