People may wish to maintain the quality of their mattress by using a mattress protector. The best mattress protectors offer protection from spills, allergens, and keep people cool while they sleep.

Quick links

Generally, mattress protectors can help maintain a mattress, improve a person’s sleep environment, and boost comfort.

They may be beneficial for people who enjoy eating or drinking in bed and those prone to accidents. Many healthcare settings may also use mattress protectors on hospital beds.

Sleep plays a vital role in optimal health. Adults need 7 or more hours of sleep per day, but roughly 7–19% of adults in the United States report not getting enough sleep. This can result in potential health complications.

Choosing the correct mattress is one way to try to achieve better sleep, and using a mattress protector may be one way to prolong the life and quality of a mattress.

A mattress protector is a piece of bedding that sits on top of a mattress.

Typically, a person will place a mattress protector over the top of a mattress in the same way that they may fit a sheet. Modern mattress protectors are often elasticated to make fitting them easier.

Generally speaking, the purpose of a mattress protector is to:

  • protect the mattress and prolong its quality

Mattress protectors sit on top of mattresses and can help protect them from fluids, including urine, sweat, drool, and other general spills.

A person can easily remove and wash a mattress protector, often in a domestic washing machine, before placing it back onto the mattress. This is helpful, as cleaning a mattress itself can often be challenging.

By protecting the mattress, people can prolong its lifespan, meaning they can use it for longer before having to replace it.

Another significant benefit of using mattress protectors is their antimicrobial and hypoallergenic properties. For example, while sleeping, mattress protectors can protect individuals from:

  • dust mites
  • bacteria
  • bed bugs
  • other allergens

This means that an individual may experience improved sleep and avoid issues that may arise from coming into contact with any of the above. Therefore, mattress protectors may also be useful for those with allergies.

Manufacturers may design some mattress protectors to combat uncomfortable mattresses. Other protectors work in combination with a mattress to maintain comfort and enhance breathability.

Some mattress protectors also have an additional layer of padding, which can offer a little more cushioning. This can enhance the comfort of the mattress, which may allow a person to get better sleep.

Although some mattress protectors are breathable, others are not. If it is not breathable, a mattress protector may cause a person’s bed to get hot during sleep. This can make an individual’s sleeping condition less comfortable and may contribute to reduced quality sleep.

Some mattress protectors have no built-in comfort layer, which means they can end up making a mattress less comfortable. Some mattress protectors also bunch up under the sheets, which may cause further discomfort.

Other mattress protectors may comprise materials that can make a noise when a person moves around in their sleep. For example, the waterproofing material may cause a plasticky sound during movement.

A noisy mattress protector can also contribute to reduced quality sleep.

Below are some of the most frequently asked questions about mattress protectors.

Can a mattress protector provide additional support for a person?

A mattress protector is usually very thin and acts as a barrier between a mattress and the sheet. It is unlikely that individuals will benefit from additional padding or support using only a mattress protector. Other options, such as mattress pads and toppers, could provide the extra comfort an individual may require.

How does a mattress protector secure onto a mattress?

Most mattress protectors fit over a mattress similarly to a fitted sheet — with elastic that wraps around each corner of the mattress. Some mattress protectors completely encase a mattress and become secured using buttons or a zipper.

What are the differences between mattress protectors, mattress toppers, and mattress pads?

Mattress protectors act as a thin barrier between a mattress and spills, allergens, and insects such as bed bugs.

A mattress topper can change the feel of a mattress by adding a softer or firmer layer.

A mattress pad provides additional cushioning only, which may benefit a person with a firmer mattress.

The purpose of a mattress protector is to protect and maintain the quality of a mattress. While prolonging the lifespan of a mattress, it may also provide added protection from microbes and allergens such as dust mites.

When purchasing a mattress protector, people may wish to consider factors such as the product’s breathability, its hypoallergenic qualities, and if it is waterproof.
