A fitted, waterproof protector with a breathable membrane is right for most people; it blocks spills and sweat without making you hot. Choose a full zippered encasement if you are dealing with allergies or bed bugs. Always match the pocket depth to your mattress height so it stays on.
A mattress protector is the cheapest insurance you can buy for a mattress. It blocks the sweat, spills and dust that void warranties and shorten a bed’s life. This guide covers the few choices that matter. To keep a bed fresh, pair it with our mattress cleaning guide.
Waterproof vs breathable
Modern protectors use a thin polyurethane membrane that is waterproof yet still lets air through, so you get spill protection without the crinkly, sweaty feel of old vinyl. This is the right pick for most homes, kids and anyone prone to night sweats.
Fitted vs encasement
Fitted protector
Like a fitted sheet, it covers the top and sides. Easy to put on and wash, and enough for everyday spill and sweat protection.
Zippered encasement
Fully encloses the mattress on all six sides. Choose this for allergy control or to guard against bed bugs and dust mites.
Cooling options
If you sleep hot, look for protectors with a Tencel or cotton terry top, which breathe better than polyester and wick moisture.
Fit matters
Measure your mattress height including any topper, and pick a protector with a pocket deep enough to stay put. Browse all options in our mattress protector reviews, and start with the right bed in our mattress buying guide.
