Posture Pump (Model 2000) - designed to relieve back stiffness and discomfort by stretching and decompressing the spine. Utilizes dual air cell technology to lift, stretch, and separate the joints in the back. BRAND NEW, UNOPENED W PACKAGING. Chiropractor recommended. Works great. Only reason I'm selling this one is I inadvertently wound up with two of them. Asking $65 (sells new on Amazon for $126)
