The M-2 Negative-Ion Massage Chair from Omega is modern massage therapy at its finest. Its revolutionary negative-ion oxygen technology raises the density of oxygen in stagnant air as it promotes a healthier, more enjoyable experience by increasing energy levels and lessening fatigue. This recliner includes electrically-timed thigh, calf and vibrating options, along with eight massage-heads that softly adjust the spinal column and ligaments.
