Protect your mattress with the Thomasville® Purify® Mattress Protector, which offers a ten year warranty protection against stains and dust mites. The Breathe-a-Barrier® fabric is waterproof yet breathable, keeping moisture from penetrating the protector. Although the breathable polyurethane membrane is waterproof, it is not noisy or hot to sleep on like plastic. Breathe-a-Barrier® prevents allergens from building up in the mattress by stopping dust mites and their waste from reaching the mattress. Only 1/8 inch thick, the Purify® Mattress Protector won't detract from the comfort and feel of your mattress.
