If you’re shopping for outdoor seating, the price gap between a standard backless bench and one with a backrest is one of the first things you’ll notice. On average, a basic backless outdoor bench in wood, metal, or recycled plastic costs about $120 to $400. Step up to the same material and quality tier with a backrest, and you’re usually looking at $180 to $600. In real terms, that’s roughly $50 to $200 more, or about 30% to 50% extra.
The reason isn’t just a few extra boards. A backrest changes the structure. The frame needs more support, the joints have to handle leaning weight, and the seat often needs to be slightly deeper to stay stable. There are more fasteners, more material, and more labor involved. Shipping can also cost more because the bench is bulkier and heavier. With premium materials like teak, powder-coated aluminum, or commercial recycled plastic, the gap can widen to $100 to $300 or more.
That said, the upgrade is usually worth it if the bench is a main gathering spot. People linger longer around a fire pit, dining table, or garden view when they can lean back. If you only need quick seating near a doorway, along a walkway, or at the foot of a bed, a backless bench saves money and looks clean.
If you want the comfort without the full price jump, look for a bench with a gently curved slatted back, or place a backless bench against a wall or railing. You can also add outdoor cushions for lower-back support. But when comparing the same brand and material, I’d budget about $50 to $200 more for a backrest. It’s not a massive difference, but it’s enough to plan for—especially if you’re buying multiple benches for a patio or event space.
