A waterproof mattress protector  is an inexpensive way to help extend the life of your sleep surface and safeguard your investment. It also helps prevent the growth of mold, mildew and fungus that can trigger allergy symptoms in some people. These covers and pads typically use some type of backing or membrane to serve as a waterproof barrier, but they vary in construction, breathability and level of cushioning.

Most importantly, they may differ in how long the material can be expected to last and if it’s suitable for frequent, repeated washing with cold water and gentle detergents. Those who have sensitive skin should look for cotton- or bamboo-derived fabric options, which are softer and more breathable than vinyl-like materials that can be harsh on the skin. They may not be as thick or quiet as some other options, but they can be a good choice for many sleepers.

Protect Your Mattress: Exploring the Benefits of Waterproof Mattress Protectors

Consider the Coop Home Goods Ultra Luxe Waterproof Mattress Protector for a soft, competitively priced option with a layer of polyurethane plastic that’s safe and breathable for most sleepers, as opposed to toxic foam-based plastics used by some other brands. Unlike vinyl, polyurethane isn’t known to off-gas, and it’s also a good choice for allergy sufferers.

This protector features a stretchy polyester blend with thermoplastic polyurethane for waterproofing and a soft jersey knit top layer. It’s OEKO-TEX Standard 100 certified for safety and comes in sizes twin through California king. It’s compatible with most pillow-top and high-profile mattresses, but you may need a skirt protector for thicker models.
