Bed Blocks are plastic (polypropylene) blocks designed to raise the height of a bed or chair. The blocks are round with a central indentation into which the legs or castors sit. Ribbed rubber discs are available to fit inside the indent and to provide slip resistance. The blocks are able to be stacked, up to a height of 140mm (they may become unstable if stacked too high – use caution). Able to be cleaned with bleach or disinfectant. Able to be steam cleaned and autoclaved.
