Thank you for your question! It's a thoughtful one that touches on an important aspect of modern urban design. The answer isn't a simple yes or no, but rather an exploration of intent and function.
Many contemporary outdoor benches in public spaces are indeed designed with specific features to discourage certain activities, primarily prolonged sleeping and skateboarding. However, it's crucial to understand that the primary goal is not to be punitive, but to ensure the bench serves its intended purpose for the broadest number of people and maintains its longevity.
Regarding sleeping, some designs incorporate subtle dividers or armrests between seating spaces. These provide comfort and support for seated users but make it physically difficult to lie down. The intent is often to encourage the equitable use of public seating for resting, not for overnight accommodation, and to direct those in need of shelter to more appropriate services.
As for skateboarding, you might notice benches with metal studs or anti-skateboarding ledges on their edges. Skateboarding grinds can damage the bench's structure, create safety hazards, and lead to costly repairs. These protective features help preserve the furniture for everyone's sitting enjoyment.
Ultimately, responsible design seeks a balance. A good public bench should be welcoming, comfortable, and durable. While some features may limit misuse, the core design philosophy focuses on creating inclusive, safe, and sustainable spaces for the community to sit, relax, and socialize.
