MassaMAX A675 4D Massage Chair (2026) with i-Open Flexible SL Track 125°–167°, Full Body Scan, Calf Kneading, Auto Footrest, Zero Gravity & 22 Modes

4D massage with smart body scanning: Sensors identify your anatomy and pressure points to deliver a customized program. i-OPEN flexible SL track (125°–167° adjustable) adapts in real time to deepen stretches, enhance spinal alignment and increase muscle relief. Full-body stretch combines roller kneading, air compression and gentle traction from neck to calves. Dual rotating calf rollers and an auto-extending footrest provide precise lower-leg treatment and optimal leg positioning. Zero-gravity recline reduces spinal load while lumbar heat soothes tight muscles. Twenty-two automatic programs plus voice command compatibility let you select everything from Relax to Deep Tissue hands-free. Quick setup—attach the footrest in about 5 minutes—and three control options (touchscreen, voice and armrest buttons). Includes a 3-year warranty, 24/7 customer support and access to 50+ showrooms nationwide.
