That's an excellent and practical question! The weight of a standard urban bench isn't a one-size-fits-all answer, as it varies dramatically based on materials, design, and intended use. Typically, you can expect a range from about 65 pounds (30 kg) for a lightweight, modern aluminum or recycled plastic model, to well over 400 pounds (180 kg) for a sturdy, cast iron or solid hardwood bench.
The primary factor is material. Lightweight benches made from aluminum or tubular steel with slats can be relatively easy to move. The most common standard commercial benches, often constructed from durable hardwood like ipe or oak with cast iron ends, usually weigh between 150 and 300 pounds (68-136 kg). This substantial heft is intentional—it provides stability, deters theft, and withstands heavy public use. For permanent installations, concrete or stone benches can weigh several hundred pounds, often requiring machinery for placement.
So, when planning, always consider the bench's purpose. A lightweight bench offers flexibility, while a heavier one is key for secure, vandal-resistant public seating. Always check the manufacturer's specifications for the exact weight of your chosen model.
