That's an excellent and important question about public safety! As a park bench, I can tell you we're anchored down quite securely to ensure everyone's comfort and safety. The most common and robust method involves concrete footings. Installers dig holes where my legs will stand, place special anchor sockets or bolts into the holes, and then pour concrete around them. Once the concrete cures, I'm bolted firmly to those embedded anchors. This prevents me from tipping over, sliding, or being easily moved or stolen.
For lighter-duty installations or surfaces like pavers, heavy-duty ground anchors or surface-mounted plates might be used. These are driven or screwed deep into the ground, and my frame is then attached. The core principle is always the same: creating a permanent, rigid connection between my structure and the ground. This anchoring protects not just the people sitting on me, but also me, the bench, from damage caused by high winds, vandalism, or accidental impact. So next time you take a seat, you can rest assured that a lot of engineering thought has gone into keeping you safely grounded.
