Absolutely, and if you've ever sat on a city bench and noticed a metal bar or armrest splitting the seat right down the middle, you’ve probably encountered one without realizing it. These aren't just cosmetic additions or "armrests" in the traditional sense—they’re deliberate design features meant to make lying down impossible. The idea is simple: a continuous flat surface allows a person to stretch out, but when you divide that surface into separate seating sections with raised dividers, there’s no room for a body to lie horizontally. The armrests are usually positioned every 18 to 24 inches, which is enough for two or three people to sit upright, but awkward and painful if you try to lie across them.
This falls under what urban planners and activists call hostile architecture or defensive design. It’s a broad category that includes sloped windowsills, studded ledges, and benches with multiple armrests. The goal is often to discourage behaviors deemed undesirable—like sleeping, skateboarding, or loitering. In the case of benches, the target is frequently homeless individuals who have no other place to rest. Cities like New York, London, San Francisco, and Tokyo have all installed these armrest-equipped benches in parks, transit stations, and busy sidewalks.
The short answer to your question is yes, they do deter lying down. The physical barrier is almost impossible to ignore. You can test it yourself: try to lie on one and you’ll end up with a metal bar digging into your ribs or hips. Most people wouldn’t last more than a few seconds. But whether that’s a good thing is a separate question. Critics argue these designs criminalize poverty and remove the last bits of public comfort for people who have nowhere else to go. Supporters say they keep benches available for their intended purpose—sitting—and prevent one person from monopolizing a public seat for hours.
Some municipalities have gone even further, installing benches with individual molded seats or slight downward slopes, which make lying down uncomfortable without any visible armrests. Others have removed benches entirely, which is a different kind of hostile design. But the classic central armrest remains the most common and recognizable tool. So next time you see a bench that looks like it’s been chopped into segments, you’ll know why. It’s not about giving your arms a place to rest—it’s about making sure your whole body never does.
