That's an excellent question! The short answer is: absolutely, they can be very comfortable—but it depends heavily on the design, not just the material. Let's break it down.
Gone are the days of hard, slippery plastic slabs. Modern recycled plastic (often called poly lumber) is engineered for performance. The comfort factor comes from several key elements:
1. Ergonomic Design: The best benches feature contoured seats and sloped backs that support your body's natural posture. Look for models with a gentle curve in the seat pan and lumbar support in the backrest. A flat, unyielding plank will be uncomfortable regardless of the material.
2. Material Texture: Recycled plastic lumber often has a wood-like texture that provides a slight grip, preventing you from sliding. It's also typically softer to the touch than traditional wood or metal, and doesn't get as searingly hot in direct summer sun.
3. Flexibility and Give: High-quality poly lumber has a slight, forgiving flex. This subtle give is crucial—it absorbs some pressure, unlike rigid materials. It won't sag like old wood, but it provides more cushion than concrete or untreated hardwood.
4. Construction and Proportions: Comfort is about dimensions too. A bench that's too deep won't support your back, while one too shallow offers no perch. Standard comfort heights (17-19 inches for seat height) and adequate backrest angles are vital, and reputable manufacturers follow these guidelines.
The Verdict: A well-designed recycled plastic bench rivals and often exceeds the comfort of traditional materials. It won't have the deep cushion of an upholstered sofa, but for lasting outdoor comfort that supports your back and stays cool, it's a fantastic choice. The key is to avoid the cheapest, flattest options. Invest in a design with ergonomic shaping, and you'll get a comfortable, sustainable seat that lasts for decades. So yes, you can confidently love both the look *and* the feel.
