Yes—there are several solid bolt-together urban benches I would shortlist. The trick is to look for models described as “bolt-together,” “flat-pack,” or “modular.” These usually ship as pre-drilled side frames, seat slats, and stainless hardware, so you only need a 1/2" socket wrench, a 5/32" hex key, a level, and a drill for concrete anchors.
Here are four models and series worth checking.
1. DuMor 102 Series Bolt-Together Bench
This is about as straightforward as it gets. The cast aluminum or steel side frames are pre-drilled, and the seat slats line up on stainless steel brackets. Each slat takes four bolts, so a cordless drill plus a socket wrench makes quick work of it. It is a good park-standard bench for urban use.
2. Maglin Linear Bench
A modular aluminum bench that can be specified in different lengths. The ends, seat, and back panels arrive flat with pre-threaded inserts. Most of the assembly comes down to a hex key and a wrench. Because it is aluminum, it is lighter to move but still tough enough for street and plaza use.
3. Keystone Ridge Designs Aria Bench
If you want a more polished urban look, this one has contoured cast aluminum ends and bolt-on wood or recycled plastic slats. It assembles with basic hand tools and includes tamper-resistant hardware. Expect a little more time if you add a center armrest or connect multiple sections.
4. Victor Stanley Relay Bench
A good flat-pack style bench for streets and transit areas. The frame sections bolt together first, then the seat slats drop in with stainless hardware. It can be surface-mounted or in-ground mounted, so have a hammer drill and anchor bolts ready if you are installing on concrete.
A few quick-install tips: unpack and sort the hardware before you start; leave anchor bolts slightly loose until the bench is level; use anti-seize on stainless bolts to prevent galling; and upgrade to tamper-resistant Torx or pin-in-hex hardware if the bench will sit in a high-traffic area.
If you tell me the setting—park, sidewalk, plaza, or transit stop—I can narrow it down further, but any of these bolt-together models will save you time and tool frustration.
