GIMMIC FOR SUCKERS?

Not actually - it's a device you sit on or lean against - it helps if you wriggle!!

It's designed for us unfortunates who are prone to sciatica or back pain - it's supposed to massage wayward nerve ends...

I've no idea if it has any therapeutic value -  think this strange fruit needs to be believed in. Not sure if this makes me a sucker?

It has yet to work for me :o#
