Non-porous, wipeable covering for pool noodle padding

We provided a vehicle to our local Children’s Hospital, and they requested that the pool noodles be covered so that the surface could be cleaned and disinfected. Here is the product I found that has worked well. 3" ID Black Heat Shrink Tube 2:1 ratio 3.0" wrap (4 feet) inch/ft/feet/to 80mm : Industrial & Scientific

This length was enough to cover three uprights on the Best Choice Jeep seating frame (so one and a half vehicles).
