Introducing our meticulously crafted armchair, a harmonious blend of innovation and comfort. The steel shell structure is meticulously molded in cold-cure polyurethane foam, offering a luxurious seating experience. The seat features dual levels of softness – softer in the center for unparalleled comfort and less soft on the sides for impeccable upholstery outcomes. With a center-to-center distance of 140 x 140 mm between holes under the shell, this armchair is ingeniously designed for effortless base mounting. The incorporation of wood slats both under and above the shell allows for seamless fabric stapling. For optimal upholstery results, we recommend securing the seat with the provided 4 screws before enveloping the fabric around the shell. Elevate your interior with this exceptional armchair, where functionality and aesthetics unite in perfect harmony.
