When selecting a garden bench, the backrest height is crucial for comfort and spinal health. For proper lumbar support, the ideal back height typically ranges from 14 to 16 inches (35 to 40 cm) from the seat. This height specifically targets the lumbar region—the curve in your lower back—providing essential support to maintain its natural "S" shape and prevent slouching.
Several factors influence this measurement. Your own height matters; taller individuals may need closer to 16 inches, while shorter people might find 14 inches sufficient. The bench's primary use also dictates the design. A bench for brief rests can have a lower back, while one for lengthy relaxation requires full lumbar support. The bench's angle plays a role too; a slightly reclined back (around 100-110 degrees) better distributes weight and reduces lower back pressure.
To test a bench, sit with your back fully against it. Your lower back should feel cradled without pressure points. There should be no gap between your lumbar spine and the bench back. Your feet should rest flat, with knees at a 90-degree angle. Remember, the support should be firm, not rigid. Materials like contoured wood or padded, weather-resistant fabrics can enhance comfort. Ultimately, the right bench supports your posture, allowing you to enjoy your garden in comfort, free from back strain.
