What is a mattress protector?
A mattress protector goes under your fitted sheet.
They protect the mattress from dirt, stains, spillages and bacteria build-up. 🦠
Generally, you’ll find three types of mattress protectors:
- Five-sided protectors: Fits over your mattress like a fitted sheet. It is the most convenient choice available but doesn’t protect the underneath of the mattress.
- Elastic Strap protectors: Protects the top of the mattress only with straps for each corner of the mattress. Easy to dress and remove from the mattress. It is the least protective option as it doesn’t cover the sides of the mattress.
- Encasement protectors: A six-sided mattress protector that covers all angles (including the underneath). It usually comes with a zipper. It is not easy to fit onto the mattress, which is inconvenient if you like to wash the protector regularly.
We'd recommend a five-sided mattress protector to those who want the best protection and convenience.
Why do you need a mattress protector?
The average adult sweats 118 litres a year in bed.
For an 8-year-old mattress, that’s nearly 1,000 litres of sweat built up inside the mattress.
A mattress protector can protect your mattress from bacteria and sweat and keep it feeling fresh for years to come.
On top of that, they’re a great way of preventing those unexpected accidents...

They can protect the mattress from menstrual bleeding, food and drinks, makeup and cosmetics, and accidents caused by children or pets. 💩
It’s not until an accident happens that you realise how important a mattress protector is!
Who is a mattress protector suitable for?
A good mattress cover is recommended for everyone due to hygienic reasons.
We recommend a mattress protector for the following:
- Toddlers and babies
- Pet owners
- Those with incontinence
- People who suffer from night sweats
- Those who drink and eat in bed
- Allergy sufferers
- Those who want to prolong the life of their mattress
For small children and those suffering from incontinence, a waterproof mattress protector is best.

Those who suffer from allergies will also see the benefits of a mattress protector, as it protects against dust mites and prevents dead skin cells from penetrating the mattress.
What mattress protector is best for specific needs?
A mattress protector has multiple features, and the one you choose depends on your individual needs.
Let's explore below. 👇
Best mattress protector for incontinence
Choosing the right mattress protector is crucial when dealing with incontinence, as it significantly impacts one's comfort and hygiene.
One of the main features to consider is that the mattress protector should be fully waterproof to ensure that no liquids seep through to the mattress.
Experiencing incontinence can be embarrassing, so it's important to choose a mattress protector that is also discreet. 🙊

Mattress protectors with a fitted sheet design that is noise-free are the best option.
The Nectar mattress protector is an excellent five-sided option for incontinence.
Alternatively, consider a mattress pad which has a smaller surface but is more absorbent.
We recommend the ComfortNights Absorbent bed pad, which will keep both you and the mattress dry throughout the night.
BUY COMFORTNIGHTS BED PAD£ 17.75
A mattress protector is highly important to those with allergies, as it can prevent the build-up of dust and dirt accumulating in the mattress. 💩
You should choose a mattress protector made from hypoallergenic materials to ensure it does not trigger any allergic reactions.

The ideal protector will inhibit the penetration of allergens, promoting a clean and healthy sleeping environment.
Besides being a physical barrier, a quality mattress protector should also be easy to clean, so you can remove any allergens during a simple washing cycle. 🧼
We recommend the Panda mattress protector, which is made from antimicrobial bamboo and is machine-washable.

Best mattress protector for hot sleepers
If you’re a hot sleeper, you might consider whether a mattress protector is a good idea. 🌡️

A mattress protector covers the mattress, which minimises how much it can circulate air and dissipate excess heat.
If you suffer from hot flushes during the night, choose a mattress protector designed to be cooling as well as breathable.
The Hypnia mattress protector, made from breathable and moisture-wicking cotton, is an excellent option.
26% OFF HYPNIA PROTECTOR + 2 FREE PILLOWS W/ PILLOWS2
If you're a hot sleeper, you should also consider a cool mattress to ensure the best temperature for your sleep.
Best mattress protector for babies
Babies and children have different needs when it comes to a mattress protector.
It’s important to choose a mattress protector which is safe for babies and children, as their skin can be more sensitive. 🦔
Cot mattress protectors have been specifically designed to protect the cot mattress for your baby.

The best cot bed mattress protector is generally waterproof or made with water-resistant materials to keep your little one comfortable. 👶
You should also check that it carries certifications, like the OEKO-Tex Standard 100, to ensure it hasn't been made with harmful chemicals.
Best mattress protector for bedwetting
For children who have accidents at night, it’s important to choose a mattress protector which is fully waterproof. ☔
The best mattress protector for bedwetters is one that offers optimal protection whilst being breathable and gentle on the skin.
The Night Owl Junior 2-in-1 Waterproof Fitted Sheet is 100% waterproof, making it ideal for frequent bedwetters. 💧
This protector is fast-drying and can be back on the bed within just a few hours.
Types of mattress protectors
Mattress protectors can be made out of a variety of materials with different benefits.
Deciding what type of mattress protector you need depends on what you’re hoping to get out of your protector.

The most common materials for mattress covers are cotton and polyester.
We'll dive into the key differences between these materials below.
Cotton mattress protectors
A mattress cover made of cotton is a good choice for most people.
Cotton mattress protectors are very soft, absorbent and have natural moisture-wicking properties.
These soft mattress protectors can usually be washed at higher temperatures and retain their shape well.

In addition, cotton is a naturally breathable material, making it a good choice for hot sleepers.
The Hypnia mattress protector is an excellent choice.
26% OFF HYPNIA PROTECTOR + 2 FREE PILLOWS W/ PILLOWS2
Polyester mattress protectors
Polyester is commonly used to create functional outdoor clothing.
This is because it dries quickly and is flexible.
Because of this stretchy material, it's easy to fit a polyester mattress cover over a mattress.

However, unlike cotton, it is less breathable and doesn't absorb moisture as well.
The Silentnight mattress protector is a convenient, budget-friendly option.
Waterproof mattress protectors
One of the essential functions of a mattress cover is to protect the mattress from moisture and dirt.
A waterproof mattress protector prevents moisture from reaching the mattress.
These are inexpensive and can easily be washed at high temperatures.
A waterproof mattress protector is highly recommended for babies and toddlers.
There are several different types of waterproof mattress protectors available for adults.
They are not just useful for incontinence and night sweats but also perfect for that accidental spill of morning coffee.
The Emma mattress protector is a discreet choice that is 100% waterproof.

Quilted mattress protectors
Quilted mattress protectors offer a snug layer of cushioning and protection between your mattress and sheets.
Besides adding a soft and comfortable layer to your bed, they also shield your mattress from allergens, spills, stains, and daily wear and tear.
However, they won't drastically change the feel of your mattress in the way a mattress topper will.
Our favourite is the Quilted Luxury Waterproof protector by The Fine Bedding Company.
15% OFF QUILTED PROTECTOR W/ "SLEEP15"
Mattress covers
Typically, a full mattress cover is included with your new mattress.
They wrap around the mattress to add a soft and gentle feel and give your mattress a finished look.
Zippered mattress covers are often made from cotton or polyester and are not usually waterproof.
Some mattress cases are removable and machine-washable, which allows you to keep the mattress fresher for longer.
However, we would still recommend a waterproof mattress protector with a mattress to go over the mattress cover. ☔
Some of our favourite mattresses that include a hypoallergenic mattress cover are the Emma Original, Simba Hybrid, Panda Hybrid Bamboo mattress and the Nectar mattress.
Mattress encasements
Mattress encasements are similar to mattress protectors, but they go around the entire mattress.

They provide protection against allergens, dust mites, and bed bugs, and since they cover the entire mattress are best for those with severe allergies.
Mattress encasements can also provide a barrier against liquids to some extent, although they are not always waterproof.
However, mattress encasements tend to be less popular as they are more cumbersome to take on and off the bed. 😮💨
Our favourite mattress encasement UK:
Mattress protector sizes
Mattress protectors are available in a wide range of different sizes to match any standard UK bed.
A mattress protector is available in the following sizes:
- Small single size mattress protectors - 75 x 190 cm
- Single mattress protectors - 90 x 190 cm
- Small double mattress protector - 120cm x 190cm
- Double mattress protectors - 135cm x 190cm
- King size mattress protectors - 150cm x 190cm
- Super-king size mattress protectors - 180cm x 200cm
- Emperor size mattress protectors - 200cm x 200cm
It's important to buy a mattress protector that's the same size as your mattress to ensure it fits snugly.

Most mattress protectors offer a little more give in terms of depth so that they can fit comfortably even on a deep mattress.
The Nectar mattress protector is suitable for mattresses up to 32 cm (12.5 inches) deep.
Can you wash a mattress protector?
You can wash your mattress protector to help keep it in good nick. 🧼
Refreshing a mattress protector tends to be easier than cleaning your mattress.
Washing a mattress protector will help to remove any dirt or moisture that it has collected over time.
How to wash a mattress protector
You should check the washing instructions first to find out how to wash your mattress protector.
The washing instructions can normally be found on the original packaging or protector's label. 🏷️
Most mattress protectors can be washed on a high heat between 40 - 60°C.

We recommend allowing your mattress protector to fully dry before replacing it back onto your mattress.
It’s often a good idea to buy two mattress protectors so you always have a spare to hand. 🛒
How often should you wash a mattress protector?
It’s up to you how often you wash your mattress protector, and this can be different depending on your lifestyle.
If you sweat a lot during sleep or suffer from allergies, then it might be wise to wash your protector as often as your regular bedding. 🧺
For others, you might only wash your mattress protector every couple of weeks or months.
If you spill liquid on the bed or have an accident, pop your protector in the wash immediately with the rest of the affected bedding to prevent stains. 🍷
Is a mattress protector worth it?
Yes! 😍
We definitely think you should invest in a mattress protector if you don't already have one.
A mattress protector safeguards your bed from dust mites and bacteria, accidents, as well as the accumulation of sweat and moisture.
When you break the bank on an expensive mattress, it only makes sense to protect it as best as you can, as it will prevent the need to replace the mattress as often. 💰
