When it comes to supporting your back during long drives or extended sitting, wedge cushions often offer more ergonomic benefits than regular car seat pillows. A wedge cushion is specially designed to tilt the pelvis slightly forward, promoting a natural curve in the spine and encouraging proper posture. This positioning helps reduce pressure on the lower back, making wedge cushions especially effective for people with lumbar discomfort or posture-related issues. On the other hand, regular car seat pillows typically provide flat or cushioned support, focusing more on comfort than posture correction. While they may offer short-term relief and softness, they often lack the structured design needed for spinal alignment. Over time, this can lead to slouching or increased strain on the lower back. https://billebon.com/collections/car-comfort
