Custom armchairs were provided for the National Archaeological Museum in Naples, among the oldest and most important in the world in terms of the richness and uniqueness of its heritage and its contribution to European culture. The NAMN has invested greatly in scientific activities and collection refurbishment, consolidating its ties with leading international museums, and internal services. Among the most notable projects is definitely the complex and substantial renovation and expansion of the Braccio Nuovo building by Gnosis Progetti. It is home to restoration workshops, a cafeteria, a specialist library, a photo library, areas for themed exhibitions and educational activities, a storage area, and a large auditorium that seats around 300 people. For the latter, which is the crowning jewel of the Braccio Nuovo building, 288 custom, fully upholstered armchairs with variable wheelbase were supplied and installed, equipped with gravity-driven tip-up seats and arranged in curved tiered rows.
