How to Waterproof a Mattress for Outdoors

Daybeds are perfect for lounging outdoors in style. They can add to your exterior décor and provide a cool spot for relaxing on warm days.

It’s no surprise that many people including myself want to have them on their patios, in tree-houses or near the pool. However, outdoor furniture is often expensive and you may end up abandoning their dreams of getting a beautiful, comfortable outdoor space.

Furniture placed outside is likely to get at least a little wet and as you probably know, mattresses absorb moisture easily.

The wet sponge then becomes a heaven for mildew, fungus, and mold. Because of this, you will need a waterproof mattress for your daybed and it all comes down to the budget you have

If you want a long-term permanent solution, go with an outdoor mattress.

If you want to save some money, waterproof an ordinary mattress using simple materials. Not only is this option cheaper, but you can choose the exact texture and style of fabric you want. Whether you want beach club-style luxury or a more rustic vibe, you can create it.

Read our post about how to waterproof a mattress for outdoors - and find three outdoor mattress options after that.

These covers are made by the famous brand Sunbrella that is well-known for their outdoor textile. Some of the qualities of Sunbrella fabric include:

  • water and UV resistant
  • breathable
  • air-dries very quickly
  • fade and stain resistant
  • machine washable and dry-able
  • will not mildew

The protector covers your mattress from all sides including the bottom. It zips on over your mattress and fully encases it.

Waterproof Sheets

A more budget friendly alternative to a waterproof mattress cover is waterproof sheets.

For example, this one below comes in a form of fitted bed sheets. You can choose from four sizes: Twin, Full, Queen, King. It also comes in 6 different colors and has a 10-year warranty.

While plastic encasings can also be an option; however, these aren’t very comfortable, and they can be noisy and unattractive.

Look for a modern alternative which offers a cozy, comfortable top layer and a waterproof layer below. Some are even specifically designed to encourage airflow so you remain cool on hot days.

Waterproofing Spray

If you want to make your mattress waterproof with as little effort as possible, get a waterproofing spray.

All you need to do is place the mattress outside and lightly spray the entire surface.

Make sure you hold the can six to eight inches away from the fabric to ensure even coverage. Let each pass overlap slightly to ensure you don’t leave out any spots. The fabric does not need to be saturated so don’t overuse the spray.

After applying, allow the mattress to dry for about four hours and then apply a light second coat.

Once this dries, test the mattress with a little water. 

If the water beads up on the surface but doesn’t soak through, you’ve done your job. The next time it rains or you spill a drink, all you need to do is wipe off the liquid. The mattress will be well protected.

Some waterproofing sprays also protect from sun damage so you’ll be even better able to maintain the mattress.

DIY Waterproof Cover

Another option is to cover the mattress with waterproof fabric. It can be a fun DIY activity.

Since the key to maintaining an outdoor mattress is ensuring it is protected from moisture, humidity, and sunlight, you will need to choose fabrics that can withstand a range of elements. Fabric stores should have a range of waterproof poly-blends from which you can choose.

The fabric below comes in 13 colors and is perfect for this project.

Here's what you need to do:

  1. Measure the mattress
  2. Cut the fabric accordingly
  3. Get crafty! Use fabric glue or use a sewing machine to put the cover together

This can be a fun DIY activity for a family!

Other Ways to Protect Your Outdoor Mattress

Where you place your mattress is also important.

Despite your best efforts, a bed which is completely exposed to the elements won’t last as long as one indoors.

If you have a partially enclosed gazebo, porch, or deck, you sha pop-up canopyould cenclosed gazeboonsider storing the mattress there when it is not in use. Keep it covered with a thick mattress cover. That way, it is protected from moisture, rain, and snow. If you leave it out, you may not be in time to remove it when bad weather threatens. It is better to be safe than sorry.

Garages, pool houses or sheds are also great for storage if you will only be using the mattress on special occasions. It may take a little more effort to move it after each use, but it will last a lot longer. At the very least, lean the mattress again the wall of an enclosed porch during bad weather.

If you have your mattress in a cabin or treehouse, you also need to keep it covered. If you can, keep it away from any openings in the structure. Alternatively, you can try to close up the spaces when the area is not in use. You also need to keep out bugs which can chew through the plastic covering and undo all your hard work. A mesh screen can keep most of them out.

Maybe your daybed is an integral part of your outdoor décor and you want to have it out at all times. If so, consider installing a pop-up canopy or even a regular hardtop gazebo to house it.

You can even get outdoor curtains to add some extra elegance while adding even more protection from mold and mildew.

When you take these steps, you can relax knowing that your mattress won’t be damaged by moisture and its life will be extended.

How To Buy The Best Waterproof Outdoor Mattress

Gel Memory Foam Vs Air Mattress: Which One Is Better? 

Buying an outdoor mattress can be overwhelming since there are many types to choose from. Today, I will focus on gel memory foam and inflatable mattresses. 

Let’s look at their pros and cons. 

Gel Memory Foam

Gel memory foam has better temperature regulation than other foams. It does not trap heat but offers a cooling effect, which makes it ideal for outdoor use. The open cell structure also makes it more breathable

The Classic Brands daybed mattress  offers these perks since it is partly made of gel memory foam.

Keep in mind that a gel-infused mattress costs more and the cooling effect may not last throughout the whole night.

Air Mattress 

Air mattresses also offer temperature stability. It will keep you cool as long as you keep it in the shade. The plastic can overheat in the sun. 

The biggest advantage of an air mattress is its portability and easy storage

Don’t have enough garden chairs for your unexpected guests? Simply inflate the Intex air mattress  for a casual get-together. 

On the downside, this air mattress is prone to leaks. The punctures tend to first appear at the seams. 

Benefits Of Buying A Waterproof Outdoor Mattress

Here are some of the benefits of buying a waterproof outdoor mattress instead of making one:

  1. Made for outdoor use
  2. Ready for immediate use
  3. Should last you longer 
  4. Waterproof spray and cover not needed
  5. No accidental water absorption 
  6. Some are covered by warranty 

Best Mattress For Outdoor Daybed Is …

The clear winner of my review roundup is the Classic Brands daybed mattress .

I have picked it because it looks like a classic mattress while being waterproof. It is partly made of cooling gel memory foam, which is ideal for outdoor use during the summer. 

Unlike the air mattresses on my review list, this one will make your patio look classy. The French tufting and hand-rolled edges are small details that make all the difference.  

The runner up worth mentioning is the Intex air mattress . This one lets you create a bedroom experience under your pavilion. Its gray-toned velvety exterior adds to the comfort that can be easily amped up with few tricks.

Making Your Newly Waterproof Mattress More Comfortable 

Once you have a waterproof mattress and a plan for keeping it away from the elements, you can get more creative.

You can turn your attention to sheets and pillows or throw cushions.

Add some Egyptian cotton sheets to make the space even more comfortable. These soft, high-thread-count sheets create a luxurious hotel-like experience right at your own home. You just need to remember to remove them after use and take good care of them.

You can also add colorful pillows or throw cushions to liven up space.

As with the mattress, you will have to waterproof them or only put them outside when you will be using them. You can even make your own accents if you want full control over your new outdoor haven.

How To Waterproof A Mattress For Outdoors: Final Words

At first glance, it may seem difficult to waterproof a mattress for outdoor use.

However, as you can see, it can be as simple as using a spray and keeping the mattress away from the elements wherever possible.
