The fabric may have a non-skid surface to resist sliding in use. The wedge conforms to a patient's or infant's body. When compressed, the fabric envelope and beads lock into a roll-preventing support structure. One alternate version has a stabilizing panel extending from the pointed end of the wedge on which a patient lies. Another version has a connecting panel between two opposing triangular shaped wedges. It provides roll preventing support for a pregnant woman and doubles as an anti-roll pad for infants. | |
