Set of two modular “Acca” chairs in thermoformed plastic, designed by Archin Studio Martini. The distinctive feature of this project is its dual functionality: each element can be used as a chair or a stool, and can be disassembled and stacked, allowing for flexible and space-saving configurations. The soft, sculptural shape recalls a post-modernist aesthetic from the 1970s and 1980s, with accentuated curves and a comfortable seat. The single-piece molded plastic structure ensures lightness and easy maintenance, while the ability to stack or combine multiple modules makes it suitable for both domestic environments and contract settings with a creative and informal feel. There are two complete chairs, each composed of two stackable/stackable elements. Overall good condition, with normal signs of aging, cracks, abrasions, and traces of use on the plastic surface (see details in the images). Dimensions (approximately): Width: 58 cm Depth: 51 cm Height: 70 cm Height seat: 43 cm
