The Bed Heel Raiser is deigned to lift the heel off the bed.
About the Bed Heel Raiser
It is 20cm / 8″ long and the high end and can hold the heel 4cm /1.5″ off the bed, depending on the weight of the ankle and foot.
The inside surface of the foam is convoluted. This helps reduce pressure underneath the ankle.
The covers are made out of a soft vinyl. They are 100% heat sealed, so cleaning can be done by wiping with normal hospital grade disinfectant.
