I spent a great deal of time researching massage chairs and was extraordinarily impressed by the reputation and quality of Inada. I'm ecstatic to now be the proud of owner of a Flex 3s. The Full Body session is absolutely divine! I have lower back pain, and it helps me tremendously. And, the way opens up my chest as it draws my shoulders back and down is amazing! On top of all that, I sleep so much better - miraculous! What a fantastic chair! I'm super excited about my purchase as it certainly adds so much value to my overall quality of life. I love my Inada massage chair!
