Teeter Better Back Acupressure Nodes, Multicolor TARGET TENSION & RELIEVE PAIN: Enhance your inversion experience by adding Acupressure Nodes. Targeted pressure-point relief helps to release tension, increase circulation, and relive muscle discomfort. VARIABLE PRESSURE: Use the nodes at a static incline for steady pressure or oscillate by rocking up and down for a shiatsu-style massage. CUSTOMIZABLE RELIEF: The grooved bed track of your Teeter Inversion TAble allows you to adjust the placement of the nodes to target tense muscles along your back. Includes 4 sets of 2 nodes in a range of heights for varied pressure. CONVENIENT DESIGN: A twist lock design makes the nodes easy to attach and adjust. MAXIMUM COMPATIBILITY: Use with any of Teeter's ComforTrak or FlexTech bed models. Also fits in the Better Back Lumbar Bridge or Decompression Arch for even deeper lower back pressure-point relief.
