It really depends on the piece. “Typical urban outdoor furniture” covers everything from lightweight café chairs to heavy public benches and planters, so there’s no single weight. As a rough guide, loose café chairs usually weigh about 4–8 kg, with heavier armchairs around 6–12 kg. Small side tables are often 5–10 kg, standard café tables 12–30 kg, and larger dining tables 25–50 kg. Public benches are much heavier: many loose benches run about 30–80 kg, while fixed or institutional benches can be 80–150 kg or more. Planters are another big variable—25–100 kg empty is common, and once filled with soil they can be far heavier. Umbrella bases often add 20–50 kg.
Can one person move it? Often yes, but not always safely. A single person can usually move lightweight outdoor café chairs and small side tables without much trouble. Medium tables may be movable by tilting and rolling them on two legs, but that depends on the design, surface, and whether the table is stable enough. Larger tables, public benches, and filled planters are usually a two-person job or a job for a furniture dolly. If a bench has a public bench weight of 70 kg or more, dragging it alone is a bad idea: it’s hard on your back, can damage paving, and may tip unexpectedly.
The biggest clue is whether the furniture is designed to be movable. Look for handles, wheels, lightweight frames, stacking features, or a loose, unanchored base. If it’s bolted down, weighted with concrete, chained, or part of a fixed streetscape, one person should not move it at all. Also check for locks, brakes, and removable parts before you try. For outdoor furniture safety, test the weight first by lifting one corner slightly, clear the path, wear gloves, and keep the load close to your body. Use a dolly and straps for anything awkward or above about 25–30 kg. So the short answer is: one person can move many loose urban outdoor furniture pieces, especially chairs and small tables, but most public benches and filled planters need two people or equipment—and fixed furniture should be left to the people responsible for the site.
