An urban bench typically weighs between 150 and 250 pounds (68–113 kg) if it’s a standard metal or wood-slat design. Lighter aluminum or recycled plastic benches can be as little as 60–100 pounds, while concrete, stone, or heavy cast-iron benches can easily run 400–800 pounds or more.
So, could two people carry it? For the common 150–250 pound bench, yes—provided both people are reasonably fit, the bench isn’t bolted to the ground, and you can get a solid grip on both ends. The main issue is the shape: a 5–6 foot bench is long and unbalanced, so lift from the ends, keep it level, and use gloves for grip. If the bench is over 250 pounds, made of concrete or stone, or placed in an awkward spot, don’t attempt a two-person deadlift. Use a dolly, moving straps, or bring four people.
Before moving any urban bench, check for bolts, brackets, or tamper-proof screws. If it’s fixed to the pavement, unbolt it first. Clear the path, plan where you’ll set it down, and lift with your legs rather than your back. In short, two people can handle most standard urban benches, but heavier or bolted-down units need extra help or the right equipment.
