But fret not; I’ll provide you with a first-person view of the features I find impressive with ratings.

  • Extendable footrest feature 10/10: Loved the feature; it just creates so much convenience. I’m about 5’7” and could fully stretch my feet out, without compromising comfort.
  • Computerized Body Scan 10/10: This targeted approach enhanced my overall massage experience. It almost felt like a skilled masseuse relieving tight knots and fatigue from my body.
  • Auto programs 9/10: There wasn’t such an issue with the programs, everyone performed well on their part. However, I wished for some chiropractic massage techniques like SV-Chiro, as offered by other alternate massage chairs.
  • Controlling system 8/10: It’s a good thing to have two alternate ways to control a device. However, I got a bit confused when personalizing the message. The manual control was somewhat uncomfortable and to be honest, I didn’t use it as much as I used the wireless remote. I felt they charged me dollars more for the big LCD screen when I could just afford to buy another remote in case it stopped working.

Well, that was my overview of the Osaki OS-4000 massage chair and like I said, each person’s view differs from the other. If this review helped you, I encourage you to invest in the Osaki OS-4000 massage chair.

This positioning is accredited as the optimal state in which our body tends to work at its best, and here’s why: Increased intensity of massage as your back is virtually supported by the backrest. At the same, reduced vertical stress on the spine because of elevating the lumbar region and elevating the legs above the heart helps promote blood circulation. In the second stage, your body experiences a greater recline and, thus, greater relaxation.
