You’re not imagining it—those center armrests are often designed to make sleeping difficult. In short, yes, they do stop most people from stretching out and sleeping on the bench.
In many cities, this is a form of hostile architecture, also called defensive design. The idea is simple: if you place an armrest in the middle, a person can still sit on either side, but they can’t lie flat. The armrest hits the back, hips, or ribs, making it uncomfortable to sleep for more than a few minutes. Some people may curl up in a tight position or sleep on the ground nearby, but the bench itself no longer works as a bed.
Officially, cities may say the armrests help elderly or disabled people stand up, discourage skateboarding, or keep benches looking orderly. Sometimes that’s true. But when you see a bench with two or three armrests evenly spaced, or a row of bucket seats, the real purpose is usually behavior control—especially discouraging homeless people from sleeping there.
Does it work? As a deterrent, yes. As a solution to homelessness, no. It simply moves people out of sight, often into more dangerous places like alleys, underpasses, or emergency shelters that may be full. That’s why many housing advocates, architects, and city councils have started pushing back against hostile design. Some cities have even passed rules limiting it, arguing that public space should be welcoming rather than exclusionary.
So yes, those middle armrests are a quiet signal that sleeping isn’t welcome. But they also raise a bigger question: if a city has to design benches to keep people from sleeping on them, the real problem isn’t the bench—it’s the lack of safe, affordable places for people to sleep.
