This is an acupressure mat.
I actually have the acupressure foot board (well it is plastic – and it has magnets) and here is what it looks like – my mother gave this to us on her last visit in June – and I think it designed to “stimulate circulation” and bring oxygen flow throughout the body. We have not noticed any differences at our place. This kit had a “thumb acupressure” piece, but she did not have that anymore so I could not try it out.
Here are the sheets that came with the acupressure foot board:
Well I think we all prefer the old-fashioned. classic type of massage!
have a great day
and peace out.
