Some say it's noisy in use

Our top pick of the best mattress protectors is Purple. Here the leading mattress maker has thrown its expertise into creating a dual-layer mattress cover that safeguards against spills, dust mites and stains. A water-resistant inner layer prevents wetness from soaking through, while an absorbent outer layer dissipates liquid (including urine) so that it doesn't puddle.  

The five-sided Purple Mattress Protector covers everything apart from the underneath of your mattress and is designed to be stain-resistant, as well as machine washable.

You can buy it in seven different sizes, from twin to split king, and several different colors. We often see it pop up among the Purple mattress sales too, so you can usually save a few dollars on the price tag.

In terms of users reviews, the Purple Mattress Protector has a rating 4.4 out of 5 stars on Purple, and 4.6 out of 5 stars on Amazon. While there's lots of praise for the high levels of protection against spills and stains, a few users have said that despite Purple saying the fabric is quiet in use, theirs was noisy.

Purple's offering is one of the most expensive options in our guide, but if you want best mattress protector bar none, and one that's designed by a top-rated mattress in a box brand and that's covered with a 10-year warranty, here it is. 

Purple Mattress Protector: From $79 at Purple

Purple Mattress Protector: From $79 at Purple
If you purchase your mattress protector directly from Purple, you will pay full MSRP. However, if you're intending to buy sheets also, then you can save a very healthy 25%. However, it is also worth keeping an eye on Amazon, who occasionally drop prices of the popular Purple Mattress Protector by 15%, which brings the price of a queen down to $84.15 instead of $99.

Not the best with flat sheets

The Brooklyn Bedding Luxury Cooling mattress protector isn't just a premium protector, it's designed to help your mattress feel cooler to the touch.

Material: Cotton
Sizes: 6 (twin - Cal king)
Trial: 100 nights
Warranty: 5 years
RRP: $99

Expensive in the smaller sizes

Not only is the Nectar Mattress Protector designed to safeguard your bed from spills, stains and allergens, it can also boost your in-bed comfort a little, putting it someway between a mattress cover and a thin mattress pad. 

The stretchy, non-slip design will fit mattresses up to 22 inches tall, and is easy to wash – simply machine wash and tumble dry on a low setting to freshen it up. Other perks include a five-year warranty, free shipping and returns, and a 50-night trial. 

No matter what size you choose, the waterproof Nectar Mattress Protector is a straight $99 – great if you’re after a Cal King, but it seems a tad unfair if you're just buying for a twin size bed. However, if you factor in the comfort on offer, then you might not mind paying a little extra for the smaller sizes when you can get a mattress cover with a padded cotton top for extra plushness.

Nectar Mattress Protector:

Nectar Mattress Protector: From $99 from Nectar
Regardless of whether you're buying a twin or cal king size mattress protector, the price remains $99 when you purchase directly from Nectar. While there's currently up to 40% off Nectar mattresses, unfortunately that saving doesn't extend to their best-selling mattress protector. It's still excellent value, especially if you're buying for a bigger bed (it's less of a steal for those looking to buy a twin size).

The SafeRest Premium Hypoallergenic Waterproof Mattress Protector is designed to do exactly that, and has a user review score of 4.6 out of 5 on Amazon.

Can't be ironed

If you're looking for an eco-friendly mattress protector to go with your organic mattress, try this 340gsm Utopia Bedding Premium Bamboo cover. It has a very slightly cushioned top, meaning it isn't as thick as a mattress pad and certainly not as plush as a proper bed topper, but it will add in a little extra comfort. 

Like other waterproof mattress covers in the guide, this one has a TPU to protect the top of the mattress - so the sides won't have the same waterproofing. It will help to protect against sweat stains, body oils and other moisture, and because bamboo is naturally breathable it won't collect heat either. 

If you prefer mattress protectors without thick elasticated bands, you'll love the design of the Utopia Bedding Premium Bamboo cover. That's because it opts for a Smooth Grip Skirt System, infused with elastic so that you can simply pull the borders of the pockets down to make it stretch over the mattress. 

Utopia Bedding Bamboo Mattress Protector: $29.99

Utopia Bedding Bamboo Mattress Protector: From $29.99 $14.99 at Amazon
Prices start at just $14.99 for a twin size Utopia Bedding Bamboo mattress protector from Amazon, thanks to 50% off sale. However, there's only a 5% saving on a queen size protector, which brings the price down fractionally to $17.99 from $18.99. Still, this is a great price for an eco-friendly product with overwhelmingly positive consumer reviews.
