The document introduces the SIT+LOCK, a new generation of street furniture that combines an outdoor lounger with an integrated payment locker. The SIT+LOCK is ergonomically designed for relaxation and allows users to securely store belongings in the locker while getting food or relaxing. It is made from durable and weather-resistant recycled plastic lumber and comes in five bold color combinations. The modular design allows for flexible arrangement and the furniture is secured to the ground. The SIT+LOCK can be implemented in public spaces like plazas, parks, and waiting areas to create a social, relaxing, and smart environment.
