What to look for in a mattress protector

The best mattress protector for you combines the protection you need with a secure fit, comfortable feel and easy care.

1. Waterproof Protection

For protection against spills and nighttime accidents, look for a waterproof mattress protector rather than a water-resistant option. Check whether the protective barrier covers just the top or extends to the sides, too.

2. Fit And Coverage

Match the protector to your mattress size and measure its height, including any topper, to choose the right pocket depth. A fitted style covers the top and sides, while a zippered encasement surrounds the entire mattress for more complete coverage.

3. Comfort And Breathability

Look for breathable fabrics and a smooth, quiet surface that helps preserve the feel of your mattress. If you tend to sleep warm, compare moisture-wicking features and cooling materials rather than assuming every waterproof protector sleeps the same.

4. Care And Durability

Check the care label for machine-washing instructions and dryer settings that work with your routine. Following those instructions helps maintain the protector’s fit and protective barrier through regular cleaning.

What materials should I compare when choosing the best mattress protector? + -

Common mattress protector fabrics include cotton, polyester, lyocell and blends. Some designs also include a polyurethane backing. Compare the listed fabric composition, surface texture and care instructions to find an option that matches your preferences.

What styles of mattress protectors are available? + -

Common styles include fitted protectors with an elasticized skirt, designs with elastic corner straps and zippered encasements. Fitted and strap styles cover the top surface, while encasements surround the mattress on all sides.

Does a mattress protector go under the fitted sheet? + -

Yes, a mattress protector generally goes directly over the mattress and beneath the fitted sheet. If you also use a mattress topper, check the manufacturer's layering instructions, since the recommended placement can vary.

How do you wash a mattress protector? + -

Always follow the care label, since washing and drying instructions vary by fabric and construction. Many mattress protectors are machine washable, but permitted water temperatures, detergent types and dryer settings differ. Check the label before using bleach, fabric softener or high heat.

What is the difference between smooth and quilted mattress protectors? + -

Smooth mattress protectors have an unquilted fabric surface. Quilted versions feature stitched patterns and may include a light layer of fill. Check the construction details to see whether a quilted design contains fill or simply has decorative stitching.
