Breathable, cool & supportive cotton protector So you've invested in a beautiful mattress? Keep it beautiful with this luxury mattress protector. Filled with pure cotton, it's breathable & helps wick away moisture for a good night's sleep. We've strip stitched the filling for a soft, cushiony feeling; so it's a great buy for giving an existing mattress a boost. The natural cotton top layer & filling are soft & cooling. In fact, it's a great addition to a memory foam bed if you're finding it a bit too warm at night. A jersey skirt holds this protector safely on your bed, & is available in two depths to fit standard or deeper mattresses.
