I bought this maybe 5 years ago when I had back problems. I no longer have back problems, but can't say that it was the inversion board that fixed it. It did feel good on my back, though, that is for sure. Now my back is fine and this is taking up space.
You will need a truck or large SUV with the seats folded down to pick this up.
I'm in Moraga. Free to a good home. And if your back hurts, I'll carry it out to your truck while you take a couple of Advil. It's not heavy, but is a little awkward.
