How do I care for and clean this mattress?

This is the thickest bed in the line at 13 inches, and its Cool-To-The-Touch cover unzips for cleaning. Dry clean that cover only; a washer and dryer will shrink the cool-touch fabric so it no longer stretches over the tall foam. Treat spills on the foam with a lightly dampened mild-soap cloth and let it dry right through before re-covering. Add a protector, and rotate end to end since it never flips.
