The short answer is that there is no single standard weight for every concrete bench, because finished weight changes with length, seat thickness, backrest design, reinforcement, aggregate, finish, and drainage details. At our outdoor bench factory, most standard backless concrete benches for parks, campuses, and streetscapes fall between 200 and 350 pounds (about 90–160 kg). A typical 6-foot bench with a backrest and armrests often lands around 300–450 pounds (136–204 kg), while heavy-duty commercial models built for high-traffic public spaces can exceed 500–800 pounds (227–363 kg). These weights are intentional: the mass helps resist wind, tipping, and daily public use. For shipping and installation, we recommend confirming the exact model weight, lifting points, and surface protection requirements before delivery. If you need a lighter option for rooftop or temporary installations, we can also discuss thinner profiles, hollow-core designs, or alternative materials. For precise planning, our factory provides a per-model weight specification rather than relying on a general estimate.
