By relieving pressure in certain places, the S- and L-shaped massage tracks of these chairs properly curve with the spine to align it and support it in staying that way. The back cannot automatically return to its normal posture without releasing this pressure. Look for high-end massage chairs that offer plenty of lower back and spine support. These advantages are maximized by a high-end zero-gravity massage chair, which makes it a long-term investment with quick returns.
