This is the ergonomically designed device that combines heat, massage, and gentle pressure to provide relief from lower back pain. Your own body weight works with the cycling air traction system to stretch tight muscles, while heated massage promotes healthy blood flow. The unit can inflate manually to help achieve the desired stretch or rotate through two automatic settings. Temperature levels adjust to low, medium and high, and the device shuts off automatically after 15 minutes. Panelists at the Hammacher Schlemmer Institute found the remote to be easy to use and the heated massage pleasant and effective. Black.
