What is the best mattress protector 2022?

From our research, the best mattress protector you can buy is the Purple Mattress Protector. Priced from $79 at Purple, this stain-resistant and waterproof protector will keep your mattress safer for longer, and has an impressive user review rating of 4.4 out of 5 stars, generated by over 7,200 user reviews.

For smaller budgets we’d recommend the SafeRest hypoallergenic waterproof mattress protector. This cheaper option may not have all the trimmings offered by the Purple, but it will still keep dust and particles from escaping your mattress during sleep.

How thick should my mattress protector be?

Mattress protectors are quite different from mattress toppers, and their primary duty isn't necessarily to make your bed more comfortable – although many can certainly enhance your sleep experience. 

Protectors can range from anywhere between a few millimeters and an inch. On this list, most of the cheaper, more traditional toppers are probably around a quarter of an inch thick, while more luxurious, padded items are half an inch and beyond. 

However, bear in mind that mattress protectors aren't often made from memory foam, meaning any very thick protectors may flatten over time. 

If you want a thick layer of extra padding, it's worth investing in a quality mattress topper alongside a less expensive protector. The protector will keep your mattress safe from spills, while the topper will add a couple of inches of extra cush.

How do I choose the best mattress protector?

The best mattress protector for you might not be the best for someone else, and the first thing to consider when purchasing is what you actually need it to do.

Are you buying a protector for a toddler's bed, or perhaps you have a couple of dogs that can't help but leap on right after a muddy walk? In that case, you're probably going to want a waterproof protector.

If you're looking for a little more luxury and less intensive protection, a thicker protector like Woolroom's or Avocado's might be just what you need. Others protect from dust and bedbugs, while others still provide a a quick and easy way to remedy your night-time overheating. 

If you need to find anything else out, we'd certainly recommend reading user reviews on Amazon or the company's site, as these can be quite elucidating in terms of real users' experiences.

How to wash a mattress protector

Mattress protectors should be washed every two months on average, but this changes depending on how often you use your mattress protector, whether you have been sick, and if you have allergies. Let’s take a closer look at these scenarios now to help you decide if it’s time to pop yours in the wash.

If you have allergies, aim to wash your mattress protector once or twice a month. This may seem like a lot of laundry, but it will help prevent allergens from building up inside your protector. 

If you have been ill, wash your mattress protector as soon as you feel better to banish any remaining bugs from sneezes, coughs and other mucus. 

If you have spilled drinks or food, spot clean the worst of it, then pop your mattress protector in the wash. Don’t let that stain sink in!

Guest bedroom mattress protectors can be left a little longer, unless you have had a long-term guest staying with you. 

Mattress protectors should be washed and dried as per the manufacturer’s instructions on the care label. Using a mild detergent is best, and avoid using bleach or any other chemicals that will damage the protector.

Are mattress protectors good for back and hip pain?

While some offer extra padding, if you're looking for substantial support you're going to want to upgrade your mattress with a mattress topper. They can provide extra depth and targeted support for those who suffer from aches and pains, or who have mattresses that are less than perfect.

When is the best time to buy a mattress protector?

The reality is that discounts crop up all year round on mattresses, mattress toppers and protectors. However, there are certain times of year where the savings are often a little higher than usual. 

Some such times are the Labor Day mattress sales in September, and the Black Friday and How to shop the Cyber Monday mattress deals, are also a great time to buy a new mattress protector for much less than they normally cost. 

Other times of year to note are the Presidents Day sales in February, and then the Memorial Day mattress sales in May, which normally serves up some truly unmissable deals.
