That's an easy one for me. I was in the Army so Comfort to me is a big deal. I have slept in foxholes in countries I could barely even say. My back is #1 Priority. The Osaki massage chair that I bought for my wife's back pains has been a life saver for the family. With 6 adults here it gets used a lot. So needless to say it has paid for its self 4 times. This chair is a part of my family. Our cats love it just as much as the humans. With this chair in our lives we don't slow down for a lot anymore. We just sit in, program and relax. No appointment needed. The ultimate in comfortable living for better health.
