The West Street Armchair, designed by Robin Day, is a testament to minimalist design and functional elegance. Based on a simple cube shape, this chair was initially a personal project for Day, inspired by his desire to create a chair with the simplest form. Named after the home of Robin and Lucienne Day, 21 West Street, this modern chair was later adopted by Case as a versatile desk or occasional chair.

Crafted with a solid wood frame available in oak or walnut, the West Street Armchair features upholstered leather pads on the seat and back, with the back pad slightly angled for enhanced comfort. This pared-down design originated in Day's Chelsea workshop and has been cherished by the Day family for years. Whether used as a telephone chair or a stylish addition to any room, the West Street Armchair blends historical significance with contemporary design, making it a timeless piece for any home.
