No joke , absolutely the most incredible design. It works fantastically. I can't even begin to describe how well this simple and effective spine alignment aid works. I fell asleep on it one afternoon. After I napped for about a half hour, I expected to be in worse pain than before. To my amazement, I actually felt great after relaxing in it.

There is a tolerance curve. It is not that comfortable to use but, my back does feel better and I am slowly adding more time I use it.

I use this device for realigning my spine when I have sciatica pain. I find that it can be slightly uncomfortable when you first start using it but if it is placed correctly and you relax into the adjustment, you can feel your spine slowly shifting back into correct alignment. On Tuesday, I had such bad sciatica pain. I used this device and Wednesday it was nearly gone. I think if you use it 3 times a week, it would really keep your spine in correct alignment. I love it!!

As above, it is a gift to my husband. He is using the product and likes it.

I love spine worx! I have been using it for a couple weeks and my lower back pain and sciatica that I had is almost completely .gone! Highly recommend this!

Very good;
