The ErgoRest™ lumbar pillow is engineered based on orthopedic principles that support your spine's natural S-curve. Our memory foam core provides targeted pressure relief while maintaining proper spinal alignment, reducing strain on your lower back muscles and ligaments. The ergonomic contour design follows the lumbar lordosis - the natural inward curve of your lower spine - helping to distribute weight evenly and prevent the forward slouching that leads to disc compression and pain. Clinical studies show that proper lumbar support can reduce back pain by up to 40% and improve posture within just two weeks of consistent use.
