Our waterproof dog mat liner is excellent for protecting your Ultimat, latex dog mat (or any other mat). These are to be used inside the organic cotton zippered cover for protecting the latex mattress. Dogs will be dogs! A waterproof dog mat liner will protect the mattress from spills, and body fluids, and prolong the life of the mattress for many years. The surface wipes clean and dry. Also, zips off for machine wash and dry.

This is highly recommended for puppies especially!
