An adjustable massaging device includes a track comprising two rails formed on a support structure.

In a number of deployed or massaging positions, the massaging members are in contact with the interior of the massaging surface and are capable of exerting various massage pressures. The support structure may be hinged to a bracket and pivotally mo…
