The massage cushion was a Christmas present from the son. I have recently been diagnosed with arthritis in my neck and shoulders. When I unwrapped it I thought "oh no" he's wasted his money, these things don't work.
Well, the performance of this device had me eating my words. It took a few goes to get the settings (for me) right but now when I'm a bit stiff from working, or the arthritis is playing-up, a 15 minute massage provides incredible relief from the discomfort, it's just amazing.
