The Red and Blue Chair is one of the most famous representative works of de stijl in the Netherlands. Designed by furniture designer Ritter Vader1917-1919. The whole chair is made of wood. 13 blocks are perpendicular to each other, forming the spatial structure of the chair. These structures are fastened by screws instead of traditional tenon joints to prevent damage to the structures. Ritvede hopes to strengthen the structure with pure and bright colors, so that it is completely undisguised and repainted with primary colors that conform to De Stijl's aesthetic thought. As a result, a red backrest and a blue cushion were produced. The handle and chair legs remain black, and a small amount of yellow is used to strengthen the end face. This chair expresses the profound design concept with the simplest modeling language and color. It vividly interprets De Steagall's abstract art theory in the form of a practical product and becomes a modernist design movement. ..

This chair can be said to have left its mark in the history of design. Functionally speaking, this chair is uncomfortable, but through the exhibition, it is proved that the final shape of the product depends on the structure. The backrest of the chair is red, the cushion is blue, the battens are all painted black, and the end faces of the battens are all painted yellow. Its distinctive modern form finally got rid of the influence of traditional style furniture and became an independent prediction of modernism trend. Therefore, the "red and blue chair", which embodies de stijl's philosophical spirit and aesthetic pursuit, has become a very important milestone in the exploration of modernist forms and has had a far-reaching impact on the whole modernist design movement.
