Yes, there are park benches with a central armrest designed to separate seating on each side. These are often called "divided benches" or "benches with a center divider." The central armrest serves a practical and social purpose: it clearly defines personal space, prevents strangers from lying down across the entire bench, and offers a subtle way to maintain distance in public settings.
You’ll commonly find these benches in parks, bus stops, train stations, and other high-traffic areas where privacy and comfort are valued. For example, many European cities use them to deter loitering and encourage short-term seating. In the US, they are often installed in urban parks that cater to both families and individuals.
Design-wise, the central armrest can be made of wood, metal, or recycled plastic. Some are curved, while others are straight—but all share the same core idea: to keep each side of the bench independent. If you’re looking for a bench for your own garden, you can even request custom designs from manufacturers.
In short, yes—these benches exist and are quite common. They combine function with a touch of public etiquette, making them a smart choice for shared spaces.
