Best Waterproof Mattress 2021

Last Updated: July 5, 2021

When talking about waterproof mattresses we tend to relate them to incontinence problems. Studies show✓ that nocturnal enuresis (nightly incontinence) is a common condition among kids. But getting a waterproof mattress can be a great choice for a number of reasons. They are usually very easy to clean, durable and often cheaper than normal mattresses which makes them a great option for hospital beds for example. 

If you have small kids in the family, waterproof mattresses can be a lifesaver. Whether they tend to wet the bed while sleeping, or just play around while having their evening glass of milk, it will not end up destroying the mattress and costing you a ton of money. 

We have taken a closer look at some of the best waterproof mattresses on the market. Read through our list of mattresses and have a look at our best tips for buying a waterproof mattress.

It seems like this mattress is a great choice for those with kids who are looking for a cheap but reliable waterproof mattress for their little ones.

When Should I Buy A Waterproof Mattress?

A waterproof mattress can be a great investment for a bunch of different reasons. But the most common one is because one or more family members tend to have occasional nightly accidents caused by incontinence problems. This can happen to both kids and the elderly, as well as sick or disabled people. Sleeping on a wet mattress is never pleasant and with a waterproof mattress you only need to change the sheets in case an accident happens. 

Interesting fact!
Research shows✓ that urinary incontinence and nocturnal enuresis can be inheritable. 

Another reason to purchase a waterproof mattress is that they are much easier to clean than it is to clean a normal mattress. More often than not you only need to wipe it off with a humid cloth and some anti-bacterial spray and you will get rid of whatever unwelcome liquid or stain you have gotten on your mattress. 

Waterproof mattresses also tend to be a bit cheaper than regular mattresses as they don't often contain the same amount of high-quality materials and technologies as other ones do. This is why you can often see waterproof mattresses in hospitals, vacation cabins, summer camps and similar. If you are not going to sleep on the mattress for a longer period of time it doesn't necessarily need to be overly fancy or pricey.

What To Consider Before Buying A Waterproof Mattress?

Buying a new mattress is always an important decision and there are lots of things to keep in mind in order to make the right choice. We have listed a few of those things:

Your Budget

We have already covered that waterproof mattresses generally are cheaper than regular ones but that does not mean that they are all cheap. This list shows a variety of mattresses and prices. Make sure to do your research to find a mattress that suits your nightly needs as well as your budget. 

If you are unsure about the quality of a product and you find the price a bit too high, have a look and see if the brand offers any trial period. Maybe you will find that the mattress is worth spending that little extra on and if not, you can always send it back without any financial loss.

In case you still find it too expensive to buy an entire mattress you could also consider purchasing a waterproof mattress cover. These are usually a great budget option and can be a good investment, for example, while the kids are getting used to sleeping without diapers. Waterproof mattress covers can however have a very plasticky surface and can often be a bit noisy when we turn around in bed so make sure to find one that feels right for you. 

Waterproof mattress budget

The Materials

The materials in your mattress are always of utmost importance, no matter what type of mattress you are considering buying. If you suffer from any type of allergy or skin problem you will want to make sure your mattress is hypoallergenic, anti-fungal and anti-bacterial. Have a look and see if any mattress comes with the Allergy UK seal of approval which means that they have gone through thorough testing. Two brands that have this accreditation for some of their products are Sealy and Silentnight for example.

But allergies are not the only reason why you should check the materials of your mattress. Many of us tend to overheat during the night and since many waterproof mattresses come with a PVC cover, you should check that it is also breathable. 

Some mattresses come with air vents on the sides to promote airflow in order to prevent the sleeper from overheating. The inside of the mattress, such as the springs and the filling, also plays an important role when it comes to breathability as some materials can be more stuffy than others. Some people prefer pocket sprung and hybrid mattresses, while others prefer memory foam mattresses. Make sure you know what type of materials work for you and your physical health and try to find a mattress that ticks as many of those boxes as possible. 

Thickness

A thicker mattress usually contains several layers which could potentially lead to increased comfort. Having more layers of foam or fillings will usually prevent the sleeper from noticing the springs but it is important to check the measurements of your bed to ensure that the thickness of your mattress fits. 

Sustainability

While thinking about what materials you want in your mattress, you might also want to consider another important topic - the health of our planet. Waterproof mattresses often include some plastics which may not be great. If you can afford it, try going for materials that have been sustainably sourced such as recycled plastic for example. The more organic and natural your mattress is, the better for our environment. Small conscious choices make more difference than you might think.  

Eco friendly waterproof mattress

Size

When it comes to your sleeping area - size can absolutely matter. As waterproof mattresses are somewhat of a niche product you should double-check that the mattress you have decided on comes in your desired size. Not all brands offer all UK standard sizes so it might be worth having a backup plan in case your favourite waterproof mattress does not come in a size that fits your super king bed. 

Firmness And Support

This is arguably the most important part when it comes to selecting the right mattress for you. Some people don't care too much about the firmness of the mattress, they just want something that feels comfortable but have no clear preferences. Other people, however, need a certain firmness to give their bodies the support that they need. If you tend to wake up with an aching body, you will want a mattress for back problems that provides you with pressure relief where needed. 

In waterproof mattresses, the main focus is not necessarily on a high-quality inside but rather on the outside. We would suggest that you have a look at what the mattress offers in terms of firmness, type of springs, foams and fillings to make sure it is a good fit for years to come. 

Delivery And Customer Support

You will want everything to go as smoothly as possible when getting a new mattress. Spend some time researching the company you are interested in purchasing your mattress from. What do they offer in terms of delivery? Will they be able to deliver the mattress to the room of your choice? Can they maybe remove your old mattress when delivering the new one? Look at the reviews and see what people say about their customer service. In case there is a problem with your new mattress they should be able to solve it and respond to any questions you might have in a timely manner.

Who Is The Mattress For?

Waterproof mattresses are quite common in hospitals, care homes and summer camps. If you are buying your mattress for an institution like these you also need to make sure that it meets certain criteria that might be a bit different than if you are buying it for domestic use. Among other things you should check if the materials used are fire retardant. This could potentially save lives in case there is a fire.

You should also take the interior of the mattress into consideration as many people in hospitals and care homes will spend many hours of the day in bed and can be at risk of pressure ulcers. Also, make sure that the mattresses you get can stand the weight of heavier patients without them having to be uncomfortable due to springs poking them in their backs.

In our opinion, it might be worth considering investing in a great mattress and add a waterproof mattress protector unless the sleeper regularly wets the bed or is not going to sleep on the mattress for a longer period of time. A normal mattress is generally going to be better for your spinal alignment as well as your overall nightly comfort as they tend to be made of more natural and breathable materials.

How Can I Clean A Waterproof Mattress?

It is usually very easy to clean a waterproof mattress. A humid cloth and a mild disinfectant go a long way when it comes to cleaning up urine or other liquids. In some cases, you can even take off the cover and put it in the washing machine for a more thorough cleaning. If you do so, make sure to check the care instructions carefully for the right temperature and the possibility of tumble drying.
