HELP YOUR HEALTH: Adjustable lumbar stretcher for back pain relief can help with back problems. Such as: poor posture, neck or shoulder pain, back pain, scoliosis, kyphosis, and shoulder drop. The decompression back stretcher adopts a three-point mechanical design, which can improve muscle imbalance and stabilize the biomechanical structure of the spine.

Unilateral traction can straighten the spinal curvature, while bilateral traction can lengthen the whole spine to achieve balance ADJUSTABLE: The height of the spinal decompression device can be adjusted with a rocker, and a scale on each panel allows you to visualize the stretching distance, with a maximum stroke of 4.7 inches for the actuator. The straightening belt can be moved up and down on the column to dynamically adjust the straightening position. The decompression back belt extends up to 53 inches to fit most users COMFORTABLE: The plastic outer cover and inner lining are made of breathable material. The buckle design is easy to use, users can tighten the belt by pulling on the strap, lift the buckle and the belt is instantly loosened, easy to use for the elderly too
