Extreme Bed Protector or an extreme mattress cover is a sheet of Opalo you can easily drop on top of your bed! It will also stay in place since it is secured from the sides.
 
This one yellow bed protector has the following size
160 cm x 200 cm x 15 cm (63 in x 79 in x 6 in)
 
The first image has photoshopped yellow colour and it kinda looks fluorescent-yellow which is not true. The actual bed protector looks much nicer and has a regular yellow colour :) 
 
The Opalo fabric used here is
very shiny
super sturdy
easy to keep clean
