1. The Nectar Mattress Protector

Best waterproof mattress protector (over all): available in twin to California King, this protector has your mattress totally covered

Specifications
Sizes: Twin, Twin XL, Full, Queen, King, Cal King
Material: Polyester, polyurethane and Tencel
Quilted: Yes
Reasons to buy
+Waterproof+Breathable with a cooling effect+Resistant to dust & allergies+Eco-friendly+Machine washable+Fits beds up to 22-inches deep+Quiet
Reasons to avoid
-Expensive

Why do we like the Nectar Mattress Protector? It's a 100 percent waterproof option that doesn't feel like it, thanks to superior breathability. Rather, it's a comfortable mattress protector that just so happens to do a great job of being waterproof, too.

What does it do well?

Comfort levels. It's made with Tencel (a material that's extracted from natural wood cellulose and manufactured into a very soft and ultra-breathable fabric), which makes it much more absorbent than cotton and cooler than linen. Plus, it's extremely eco-friendly. We like.

As far as waterproofing goes, this is a 100 percent waterproof mattress protector but that doesn't mean it's stiff and plasticky. Instead, it's silky to the touch, quiet and stretchy, too. Plus it's resistant to allergens and dust, making it a good buy for both allergy sufferers and pet owners.  

It's also quiet. The reason some people may skip out on a mattress protector is that they just can't deal with a protector that squeaks and crinkles. We don't blame you, it's a major annoyance, but the Nectar protector has a silky, smooth finish that stays silent, so roll around and shift your weight all you like. 

Ease of care

It's machine washable, as you'd expect from a mattress protector that's inviting spills. And tumble dryer-friendly, too.

What else?

The Nectar mattress protector is designed for Nectar mattresses, but it will fit other mattresses up to 22-inches deep. There's a two-year warranty on any defects and free delivery, too.

Perhaps unsurprisingly, this 100 percent waterproof mattress protector is ideal for use with Tempur mattresses, not only because the intelligent polyurethane membrane keeps any errant moisture away from your high-end mattress without sacrificing comfort, but also because it's been designed so that you won’t lose out on any of that memory foam mattress goodness beneath. However, it is designed to fit any mattress up to 16-inches deep.

What's it good at?
It’s water-resistant, which is great for those who tend to sweat at night – and yet it’s made from cotton terry, so it's still breathable, which means there’s no need to worry about it causing you to sleep even hotter (because that would defeat the purpose, right?). 

If you or your child happen to have asthma, the hypoallergenic nature of the mattress protector material should help reduce the risk of an attack, too.

Ease of care 
It's machine-washable and can be tumble dried.

What else?
It's Greenguard certified and free of vinyl, PVC, Phthalates, and fire retardants. Note, that it's water-resistant, not waterproof, so it won't protect a mattress from bed-wetting.

Why do you need a waterproof mattress protector?

A waterproof mattress protector will protect not just your mattress from liquid accidents but all kinds of nasties, which aren't worth losing sleep over because you know one of these covers have you sorted.

Our round-up of waterproof mattress protectors offer an extra layer of protection from potentially damaging liquids which have leaked or spilt. Most of these covers will also protect you from germs and allergies caused by dust mites. Ultimately, a mattress protector lengthens your mattress's life, protects the warranty of your mattress and boosts comfort. They can also be used alongside a mattress topper and some mattress pads with the purpose of adding cushion. Most mattress pads already add some sort of protection against dust mites and other allergens, while lacking the waterproof aspect.  

What to look for in a waterproof mattress protector

Mattress protectors are available in a range of materials and serve a number of purposes including general wear and tear, protection against allergens, dust-mites, bedbugs, cooling, and of course spills and accidents. Most of the waterproof mattress protectors on our list check off several of those functions. However, if you seek bedbug protection, you will need a mattress protector encasement, a six-sided design that covers all sides of the mattress, and requires the most effort to put on. 

For convenience, most mattress protectors are five-sided, and sit atop your mattress like a fitted sheet. Waterproof mattress protectors are usually available in a range of materials, like cotton, bamboo, Tencel and polyester combined with a waterproof layer.  

The most advanced designs use polyurethane, a super-thin, flexible waterproof membrane that is undetectable and silent while you sleep. It's also super breathable. The downside is that the waterproof layer can eventually breakdown if excessive heat from the dryer is applied. 

Traditionally, when you think of a waterproof mattress protector, your mind goes to vinyl. However, you won't find any vinyl designs on our list. While vinyl is excellent as repelling liquids and easy to clean, it runs hot and makes noise.

What is the best waterproof mattress protector?

Let's recap...if you're after the best waterproof mattress protector (in our opinion) we wouldn't hesitate to buy the Nectar mattress protector, which wins the day with effectiveness and discreet design. For little ones, we recommend the mother-approved Margaux & May crib mattress protector for protection against accidents and bedwetting.
