That's an excellent and very practical question! The answer, like many things in landscaping, is: it depends. While many sturdy outdoor benches can indeed sit directly on a level gravel base, a proper foundation is often recommended for long-term stability, safety, and to prevent sinking or wobbling.
Let's break it down. A simple gravel pad can be sufficient for heavy, solid benches (like thick stone or dense wood) placed in a low-traffic area of your garden. Gravel provides decent drainage and a level surface. However, for most situations—especially with lighter benches, high-use areas, or soft soil—taking extra steps is wise.
For optimal results, we recommend this approach:
1. Prepare a Gravel Base: Even if you use concrete, start with a 3-4 inch layer of compacted gravel or crushed stone. This is crucial for drainage and preventing frost heave in colder climates.
2. Add Concrete Footings or Pavers: For permanent stability, set concrete footings below the frost line or use large, level concrete patio pavers on top of the gravel. Place the bench legs directly on these solid, level points.
3. Ensure It's Level: This is the most critical step. Use a level during installation to avoid a wobbly bench.
Simply placing a bench on loose gravel without preparation risks it shifting, sinking unevenly, or becoming a tipping hazard. A little extra work on the foundation ensures your bench remains a steady and welcoming spot for years to come. So, while *can* they sit on gravel? Sometimes. But for peace of mind, a prepared base with gravel and solid footings is always the best practice.
