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

Sure, silky soft 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 an easy wash cycle. That's why the mattress protector should be the first thing you buy behind a new bed. Even better, they don't have to be expensive.

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. Rather, thin, undetectable layers of polyurethane accomplish the same functions. 

A good one does its job so well, you basically 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. 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 reaching your mattress. Waterproofing is always a nice bonus, and 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 these mattress protectors under your sheets.

We also love how it comes packaged with a reusable tote in the same durable cotton canvas as the mattress protector.  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.  

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.

-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, the one thing we can all agree on is 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
While marketed as cooling and breathable, some users found it not cool enough, but 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.
