Yes, it is not only possible but a common reality in many cities worldwide. Benches specifically designed with armrests in the middle—often called "anti-homeless benches" or part of "defensive architecture"—are intentionally installed to prevent people from lying down and sleeping on them.
The primary goal for city planners or property managers who choose this design is maintenance and order. They aim to ensure benches are used for sitting by many, discourage long-term occupancy, and reduce perceived loitering or sleeping in public spaces. You'll find these benches in transit stations, public parks, and near commercial buildings.
However, this practice sparks significant ethical debate. Critics label it "hostile architecture," arguing it subtly weaponizes design against vulnerable populations, like the homeless, by making public spaces unwelcoming and inaccessible for basic rest. It prioritizes aesthetics and control over compassion and universal access, raising questions about the true purpose of public furniture.
From a pure design standpoint, these benches are effective. The central armrest creates individual seating zones, limiting comfort for lying. Alternatives include segmented benches, curved seats, or even isolated perches. While they achieve a functional goal for authorities, they represent a deeper societal conflict about inclusivity, homelessness, and the right to public space. The decision to use them ultimately reflects a community's values and its approach to complex social issues.
