The provided search result context does not contain specific information regarding the proper posture for sitting on a sofa with sciatica. The content consists of website navigation and footer text rather than instructional material. Therefore, the following guidance is based on established ergonomic and clinical principles.
When managing sciatica, sitting on a sofa can be particularly challenging due to the soft, often unsupportive nature of the furniture, which can encourage poor posture and exacerbate nerve compression. To mitigate this, individuals should consciously adopt specific postural adjustments. The primary objective is to maintain the natural lordotic curve of the lumbar spine. This can be achieved by placing a lumbar support pillow or a rolled-up towel in the small of the back. It is crucial to sit all the way back on the sofa so the buttocks and back are in full contact with the cushions and the supplemental support.
Proper alignment of the lower body is also essential for minimizing sciatic nerve irritation. An individual should sit with their feet flat on the floor and their knees positioned at approximately a 90-degree angle, ideally at or slightly below the level of the hips. If the sofa is too low, placing a firm cushion on the seat can help achieve this hip-to-knee alignment. Crossing the legs should be avoided, as this can create pelvic asymmetry and increase pressure on the spine and sciatic nerve.
Finally, it is imperative to avoid prolonged static sitting. The body should be repositioned frequently, and regular breaks should be taken at least every 30 minutes to stand, stretch, and walk. When rising from the sofa, one should first move to the edge of the seat, plant both feet firmly on the ground, and then use the strength of the legs to stand up while keeping the back straight to avoid placing undue strain on the lumbar region.
