I suffer from herniated disks in my lumbar and lower back areas. The relaxing comfort of the chair helps the massage effect. the heat and all the different pulse and mode settings are great. I would highly recommend this chair for anyone that suffers from chronic back  and legs pain and muscle spasms. I have only had the chair for 2 days and already love it and can't imagine not having it.

Pros: Great value, easy to put together, great comfort.
Cons: Assembly instructions coulkd included written instructions along with the diagrams.
