Malouf Five Sided Mattress Protector Twin

The Malouf Five Sided Twin Mattress Protector provides dependable, fitted-sheet-style defense to safeguard the top and all four vertical sides of a standard Twin bed. Engineered with a laboratory-certified H2Pro® liquid-proof membrane, this ultra-thin protector creates a 100% waterproof barrier that blocks accidental spills, stains, dust mites, and common allergens while remaining highly breathable and whisper-quiet. Unlike cheap, noisy alternatives that feel like a plastic bag, its advanced design allows air to circulate naturally so it won’t alter the original comfort of your mattress or trap body heat. Finished with Malouf's signature Universal Fit™ thick premium elastic, the protector stretches dynamically to hug Twin mattresses anywhere from 6 to 22 inches deep. This heavy-duty pocket depth ensures a completely smooth, bunch-free fit that stays securely locked under the corners all night long, making it an excellent, low-maintenance choice for growing kids' beds, daybeds, or standard guest rooms.
