The best mattress protector is the unsung hero of your entire bed. 

Sure, silky-soft bed sheets are deliciously indulgent, as are the fluffiest pillows you can find. But oftentimes, these purchases are insignificant compared to your investment in the best mattress, which can't exactly go through a simple wash cycle. That's why the mattress protector should be the first thing you buy following the purchase of a new bed.

We've gone ahead and done the research as to what makes a great mattress protector.  We've only considered the best designs, ones made of superior materials like organic cotton or bamboo, and are free of uncomfortable and questionable waterproofing materials like vinyl/PVC, phthalates, perfluorinated compounds (PFCs), and butane rubber that may cause you to sweat or overheat further — especially since thin, undetectable layers of polyurethane accomplish the same functions. 

A good mattress protector does its job so well, you may forget it's on the bed until you have to deal with an unforeseen spill or stain, to discover that your mattress is perfectly protected underneath.  We're pretty particular about choosing the best waterproof mattress protector without comprising breathability. They're noiseless when you move, fit snugly on your mattress, and don't alter the feel of your mattress. A mattress protector is the first line of defense from allergens, dead skin cells, pet dander, and other irritants reaching your mattress. If you're in an area prone to bed bugs, or it's a constant fear of yours, a mattress encasement will do wonders at easing the mind.

So go ahead, we promise you'll sleep soundly with one of the best mattress protectors under your sheets.

Saatva checks off all the boxes when it comes to designing a 5-star mattress protector with all the important must-haves like waterproof, breathable, quiet, and made with responsibly sourced materials. It's easy to put on, doesn't slide around, and even better, simple to clean. 

Highlights
The organic cotton knit can wick away moisture while a thin, non-rubbery layer of polyurethane allows airflow while blocking liquids. It sits tightly and smoothly on the bed, with no wrinkles. Once it's on, you truly forget it's there.  We also love how it comes packaged with a reusable tote in the same durable cotton canvas as the mattress protector.

Good to know
After a couple of months of use, we did notice that it did like to collect little pieces of lint or lose hair.  The canvas material is also not particularly soft, but it is thick and effective in protecting your mattress from stains and spills.

Coop Home Goods nails down the combination of soft, sturdy, and waterproof, with its premium mattress protector There's just something about bamboo-derived products that are irresistible, and this waterproof protector is one perfect example. 

Highlights
The Coop Home Goods mattress protector offers some of the highest water-proofing protection we've seen in a mattress protector like a 5-gallon spill won't leak through sort of protection. It's also soft to the touch, quiet, and protects your mattress from bacteria, dead skin, allergens, or really anything that could come into contact with your mattress.

Good to know
While marketed as cooling and breathable, some users found it not cool enough. They were most likely expecting it to add cooling properties, while we'd say it's designed to stop further heat.  People with thinner mattresses also reported having to really tuck in the extra fabric on the sides, since it wasn't so snug around the rim. It fits mattresses up to 18-in thick. But fortunately, if you're not happy with your purchase, COOP offers a 100-day trial period to give you plenty of time to decide if it's the protector for you.

Not waterproof, but water-resistant

Despite everyone's unique preferences for the way we like to sleep or the mattress style that works best for one person versus another, we can all agree on the discomfort that stems from a bed that is sleeping too warm and causing you to sweat. There's a fine line between feeling snug and cozy as opposed to smothered and hot. The Casper Breathable Mattress protector uses a very soft-to-the-touch 'spacer knit' design to keep you cool and comfortable through the night. 

Highlights
The tencel-polyester spacer knit design allows air to move between you and your mattress for increased breathability and resists excess heat retention.

Good to know
It has a water-resistant design that can protect against light sweating or spills that are immediately attended to. We'd avoid it if bed-wetting or constant spills are a heightened concern of yours, but never fear, we think you'll get on fine with their original waterproof design (opens in new tab), it just doesn't have the maximum level of breathability.

Some wish it had more padding

Slip away into cloud-like luxury and protect your mattress with Ettitude's luxurious bamboo mattress protector, that's waterproof, quiet, super soft, and cooling.

Highlights
Ettitude utilizes CleanBamboo, a 100% organic bamboo, it’s silky-soft, cooling and sustainable, and uses a fraction of the water and carbon emissions produced with cotton products.  The slightly padded quilted design is also filled with Clean Bamboo, while the non-toxic TPU lining protects from spills and stains. 

Good to know
The biggest critique of this mattress pad from reviewers is that the quilted design erred on the thin side, considering they were expecting a quilted design, and wish that the padding was a little thicker. Ettitude also offers a 30-day trial period to determine if it's what you're after.

Finding a deep-pocketed mattress protector that can suit particularly thick mattresses can feel like a tall order, but Avocado has it all thought out with its waterproof design, and it's organic. 

The Avocado organic waterproof mattress protector safeguards your mattress while adhering to the company's strict sustainability standards. Avocado Green Mattress is the first mattress company in the world to achieve Climate Neutral certification, which means their entire operation is carbon neutral. They even have a special non-toxic fit for your kiddos, too. 

Highlights
To create a waterproof barrier, two layers of soft GOTS-certified organic cotton sandwich a thin, waterproof polyurethane film (which makes up only 5 percent of the overall construction). It's also made without vinyl, PVC, and phthalates, and small pores allow for breathability. 

The mattress protector is extra roomy with the ability to accommodate mattresses up to 22-inches deep. If you don't need all that material, no problem, the standard pocket size will fit most mattresses between 6-in to 16-in deep.  It can be spot cleaned, machine washed, and tumble dried on low.

Good to know
The Organic Waterproof Protector is created intentionally big because it will shrink to size as soon as you wash it.
