You’ve probably seen it: a person curled up on a public bench late at night, using it as a makeshift bed. While empathy says everyone deserves rest, urban planners and property owners often face the practical challenge of keeping benches available for daytime seating—not all-night sleeping. So, how do you discourage that without turning your city into a fortress of hostility? Here are the most effective design strategies, along with their ethical nuances.
1. Armrests and Dividers
The classic solution: install two or three armrests along the bench, spaced strategically so a person cannot lie flat. This breaks the bench into individual seats. For example, a bench with three armrests creates two distinct sitting spots—no one can curl up across the whole surface. This works because the human body needs a continuous flat area roughly the length of a person (1.8m or 6 feet) to sleep comfortably. Armrests at 1-meter intervals effectively block that.
2. Sloped or Convex Surfaces
Instead of a flat slab, design the bench surface with a gentle slope or a slight convex curve. These surfaces make lying down uncomfortable—you’ll constantly slide or feel unbalanced. Some benches have a slight arch in the middle, forcing any would-be sleeper to either sit upright or slide off. This is subtle and less visually aggressive than spikes.
3. Modular or Movable Seating
Replace fixed benches with movable chairs or stools. At night, these can be stacked, chained, or stored away. This design gives you full control over the space. During the day, people can rearrange chairs for social seating; at night, the absence of any flat surface removes the sleeping option. Cities like Copenhagen have used this in public plazas.
4. Narrow Seat Width
Reduce the width of each seat to about 30-40cm (12-16 inches). This is fine for sitting but too narrow for lying sideways. Combine it with a slight backward tilt so the user leans slightly forward, making it impossible to sleep without feeling like you’ll roll off.
5. Integrated Planters or Obstacles
Place small planters, bicycle racks, or angled elements next to or underneath the bench. This physically limits the space around it. For instance, a bench flanked by two tall planters with a gap of only 50cm prevents a person from lying sideways—their legs would hit the planters. This also adds greenery, making the space more inviting for daytime use.
6. Use of Separation
Set benches in pairs facing each other, or arrange them in a way that breaks the continuous line. A “zigzag” design where seats alternate angles also prevents sprawling.
Ethical Considerations
While these designs work, they fall under “hostile architecture”—features that intentionally exclude certain groups (the homeless, the tired, the desperate). Critics argue that such designs push people into less visible, often more dangerous spots. A better approach is to pair anti-sleep design with inclusive policies: provide public shelters, overnight warming centers, or even designated “rest zones” with padded surfaces that are safe for sleeping. If your goal is simply to keep a specific bench available for daytime use, consider adding a sign with hours (e.g., “Bench closed from 10 PM to 6 AM”) and enforcing it gently through park rangers rather than through cold metal.
Final Thought
You can prevent overnight sleeping on an urban bench, but the most tactful designs use subtle discomfort (slopes, armrests, narrow surfaces) rather than overt aggression (spikes, sharp edges). Always ask: Am I solving a problem of misuse, or am I punishing someone’s existence? The best bench design balances public functionality with human dignity.
