Yes, you can get a curved urban bench for around a tree—park benches are definitely not only straight. I’ve seen curved tree benches and circular tree benches used in public parks, plazas, school campuses, and even residential courtyards.
The main options come down to shape. A full circular tree bench wraps all the way around the trunk and works best around a mature tree with enough open space. A semi-circular or curved bench sits on one side of the tree, which is often more practical for sidewalks, root zones, or streetscapes where you need to keep a clear path. Modular curved benches are another good solution because you can adjust the radius and length to fit the site.
If you’re sourcing one, search for terms like “curved park bench,” “circular tree bench,” “tree surround bench,” or “modular curved outdoor seating.” Commercial outdoor furniture suppliers usually carry these in materials like powder-coated steel, aluminum, FSC hardwood, or recycled plastic. Some are sold as ready-to-assemble curved sections, while others are custom-built by landscape contractors.
A few installation notes make a big difference. Leave enough clearance around the trunk—usually 12 to 24 inches minimum, and more for trees with large root flare or surface roots. Make sure the base or footings won’t damage roots or trap moisture against the bark. If the tree is young or still growing, choose a bench that can be relocated or expanded later. And if the tree is owned by the city or located in a public right-of-way, check local rules before installing anything.
So no, park benches are not limited to straight lines. A curved urban bench around a tree is a realistic, attractive way to create shaded seating and make the tree a focal point.
