Condition: Brand new in package. Description A mattress is a large investment, which is why you want it to last many years so you can get great use out of it. If you don't protect it properly, you'll find that its life can be cut in half. Installing a mattress cover with zipper not only keeps the mattress safe from dirt, dust and spills, but will also keep out allergens like dust mites and mold. Nothing will permeate it and cause your mattress' lifespan to reduce. With a reinforced zipper, this cover can stand the test of time against any abuse you may bring to it. This is especially important for a cover installed on a child's bed - this model will definitely be able to handle the job! At such an amazingly low price, you can buy a few of these and have your whole home protected today.
