The short answer: a typical 6-foot park bench usually weighs between 120 and 250 pounds (54–113 kg). The exact figure depends mainly on the material and frame.
A standard steel-frame bench with wooden or metal slats—the kind found in many city parks—typically weighs 120 to 180 pounds. Cast iron or heavy-gauge steel models are heavier, often 200 to 250 pounds. Recycled plastic benches are dense; a 6-foot unit can weigh 200 to 300 pounds. Lighter aluminum or simple wooden garden benches may only be 80 to 120 pounds.
Materials matter more than length. A 6-foot teak or oak bench with a solid frame might be 150 to 200 pounds, while a concrete bench of the same length can exceed 400 to 600 pounds. If you are shopping online, check the “product weight” or “shipping weight” in the spec section—that is the most reliable figure.
For moving, treat any 6-foot park bench as a two-person lift. Even an 80-pound bench is awkward because of its length, and anything over 150 pounds is much safer to move with a dolly, hand truck, or ramp. Install it on a firm, level surface and anchor it if the bench will see heavy use or strong winds.
In short, plan for a typical weight of about 120–250 pounds, with many standard steel-and-wood 6-foot benches coming in near 180 pounds. Always confirm the exact spec before lifting or shipping.
