Best mattress protector 2021
1. Emma Mattress Protector
Best mattress protector for a luxury feel
Specifications
Reasons to buy
Reasons to avoid
This is the best luxury mattress protector you can buy, which is why it's claimed our number one spot. It says all the right things, and it certainly does a good job.
What are the main features?
This mattress cover is 100 per cent probiotic and made from Innovative Cairfull® material for a comfortable, temperature-regulated night's sleep. It's not just breathable and waterproof – thanks to the EmmaGuard layer which acts as a barrier to spills, crumbs and other unwanted nasties – but antibacterial, too.
Thanks to revolutionary AllergyShield technology, it's clinically proven to protect you from dust mites, and pet hair allergens, which is a sobering thought.
Ease of care
In terms of keeping this mattress protector clean, it's machine washable at 60°C so it's easy enough to wash any accidents away. Just DO NOT put in the tumble dryer.
What else?
As with all Emma products, the Emma mattress protector comes with a 200-night guarantee, so if you don't get on with it, you'll get your money back.
2. Avocado organic waterproof mattress protector
Best eco-friendly mattress protector (US)
Specifications
Reasons to buy
Reasons to avoid
If you want the most sustainable option to protect your mattress then we can highly rate the Avocado organic waterproof mattress protector.
What are the main features?
The Avocado organic waterproof mattress protector abides by the company's strict sustainability standards. It has two layers of soft GOTS-certified organic cotton which sandwich a thin, waterproof polyurethane film for breathable protection as you sleep. As a side note, the waterproof polyurethane doesn’t have a plastic-like crinkle or rubbery noise, and you won’t overheat, because of the the lovely cotton around it.
Ease of care
This one is meant to be washed first before first use because the GOTS organic certified cotton will shrink. It would be best to pop this in the washing machine using an eco-conscious laundry detergent. For any future washes, spot clean or machine wash, and tumble dry on low. Do not bleach.
What else?
The mattress protector is designed for Avocado mattresses, but will fit most mattresses between 6" - 16" deep.
3. Tempur Fit Mattress Protector
Best quilted mattress protector for TEMPUR mattresses (UK)
Specifications
Reasons to buy
Reasons to avoid
The perfect buy alongside a TEMPUR memory foam mattress, this ultra thin mattress protector from Tempur will ensure that your mattress remains protected yet comfortable.
What are the main features?
Despite being thin, the clever combination of a 100 per cent Tencel surface and 100 per cent polyurethane membrane ensures that it'll keep your bed fresh and dry. It's also dust mite resistant which will keep any allergies (and concerns) at bay.
Ease of care
For easy washing, it can be put through the washing machine at 60ºC and can be tumble dried at a normal temperature, so keeping it fresh and dust mite free is easy – and a quick bed change turn around is perfectly possible.
What else?
This one comes with a three year guarantee meaning that any (unlikely) defects are covered off.
4. Saatva Organic Mattress Pad
Best quilted mattress protector for other mattresses (US)
Specifications
Reasons to buy
Reasons to avoid
If you don't have a TEMPUR mattress then the Saatva organic cotton mattress pad is a good option to consider. In addition to being organic, it's made from Fair Trade Certified Cotton.
What are the main features?
The plush layers of comfortable organic cotton will add a wonderful extra layer of your mattress to your mattress, without removing any firmness. The natural cotton material has moisture wicking properties which will help create a barrier that protects the mattress underneath, and quilted stitching ensures the fill stays plump and even.
It's also fitted with an extra-wide elastic band to keep it securely in place
Ease of care
Machine wash and tumble dry, or take to the dry cleaner for even better results.

Specifications
Reasons to buy
Reasons to avoid
If you want to keep cool and cosy whilst keeping your mattress in tip-top condition, then this cotton mattress protector from DUSK should be one you seriously consider.
What are the main features?
Filled with 180gsm 100% Cotton and covered in 100 per cent cotton, this mattress protector is naturally breathable and is one which will add a layer of luxury as you rest.
It also has an elasticated microfibre skirt which will hold the protector in place so you don't need to worry about refitting it every morning.

6. Casper mattress protector
Best waterproof mattress protector (US)
Specifications
Reasons to buy
Reasons to avoid
The Casper waterproof mattress protector is one which we have recently been fortunate to review, and we are super impressed.
What are the main features?
Made from the same waterproof material used in premium outdoor gear, it'll keep spills out but large enough to let air in. It doesn't feel crinkly like a waterproof jacket, either. It feels more like terrycloth and is designed to cling firmly to your mattress (even deep ones up to 15"). It's also pretty thin so if you love the feel of your mattress, this one won't alter it one bit.
Ease of care
Machine wash on a gentle cycle with a mild detergent and then tumble dry it on a low setting for use on the same day.
What else?
There's a 100-night free trial, but we don't think you'll need it.
7. The White Company Temperature Balance Quilted Mattress Protector
Best mattress protector with some science behind it
Specifications
Reasons to buy
Reasons to avoid
This mattress product from The White Company takes temperature regulation to the next level, with some science to back it.
What are the main features?
Covered in cotton with Outlast® technology which has been developed by NASA, the fabric will store excess heat until your body temperature decreases before, then, slowly releasing the heat to provide a more consistent temperature. This out-of-this-world tech will then in a way create it's own microclimate which is tailored to you, whilst remaining soft and comfortable.
Ease of care
It's machine washable so it can be cleaned when you've stripped the bed.
What else?
The sizes available are true to size for UK mattresses.
