Some protectors pad the bed; this one simply guards it. A thin waterproof barrier keeps liquid off the top sleeping surface without adding cushioning or changing how firm your mattress feels — so the bed you chose stays the bed you sleep on. The rayon-blend jacquard top feels like fabric rather than plastic sheeting, which means your sheets lie and drape exactly as before. It also stays quiet: no crinkle, no rustling when you turn over in the night. Measuring 39″ W × 75″ L, it fits like a fitted sheet. All-around elastic and stretch pockets hold mattresses 8 to 20 inches deep, including pillow tops — check your mattress depth before ordering, since depth is the most common sizing mistake with this product. Care is straightforward: wash cold separately on a gentle cycle, tumble dry low, and skip ironing, chlorine bleach and high heat, which can damage the waterproof layer.
