The office and travel version of the Maxie-Backsie. May be used while seated to help improve posture and to apply gentle pressure on spinalerector muscles. Made of mahaganoy.
Just picked one up at Wholefoods. I'm using it while sittling in my office chair. Really corrects the posture and opens up the lungs! I notice a difference in breathing alone. I can also feel it working out a kink in a back muscle. Using it as I type this. Wow!
