“The moon is bright, and the beauty is charming ”. From ancient to modern cultures around the world, the moon has a variety of beautiful imagery to attract people. The “Crescent Moon Chair” is inspired by the association of the round-backed armchair with the crescent moon. The design breaks the traditional square shape of the chair, the dual-dimensional curve of the seat is more ergonomic, the streamlined backrest and armrests are integrated, and the lines and surfaces are interspersed and transformed. All of these form a sculptural form language, to meet the practical function of the premise, but also has a sense of physical beauty.
