Also disclosed are treads and other means for stabilizing the cushion at the therapeutic environment. The bolster type cushions might be provided with leadwardly tapered form to facilitate insertion into sleeved therapeutic devices.

A bolster-type cushion for therapeutic use, longitudinally extending for a finite-length between lead-end and trail-end along a central-axis, the cushion being predominately formed of a porous resilient structural material, the cushion along the major proportion of the finite-length cross-sectionally having a dimensionally constant and regular geometric-shape circumferentially surrounding the central-axis, the cushion having an external surface which commencing immediately rearwardly its lead-end diverges from the central-axis, said cross-sectional geometric-shape being non-cylindrical wherein a minor proportion of the circumference thereof includes a recessed channel in a circular shape having a sectorial extent within the range of 190.degree. to 290.degree., and further comprising:

(a) handle means at the cushion trail-end;
