Homedics' Shiatsu Massage Cushion turns any chair into a Shiatsu massage chair. Never in your life will you experience a more invigorating massage; you'll actually feel as if a massage therapist is hidden inside the massage cushion. A state-of-the-art moving dual massage mechanism travels up and down your back, melting away tension, muscle pain and fatigue. Need to pinpoint that exact ache? With Shiatsu Plus spot massage, you can do just that! And, at the touch of a button, adjust the width of the massage rollers custom for your body. You're going to wish you never had to get up. In fact, it's so good that Consumers Digest has awarded the SBM-300H a Best Buy award.

When you find that ideal spot, you can hold the massage to help work out the even the tightest knots, thanks to the integrated Spot Shiatsu system. An adjustable width setting for Rolling Massage lets you adjust the massage rollers on either side of the spine for a custom-tailored experience. Meanwhile, in-seat massage offers an invigorating vibration massage that aims to increase circulation.

The SBM-300H comes with six programs: full, lower, or upper back in Shiatsu, plus a rolling massage for each of the three modes. The SBM-300H's integrated strapping system attaches easily to most home and office chairs.

Rating : - Works Good for only 2 months
My family members really enjoyed using this machine but unfortunately it started making loud noise after about 2 months and I returned it for refund (no shipping charge) but had to pay 25% restocking fee plus the original free shipping charge.
