A good sleep on your boat bed is all that you need for the perfect sailing experience!

And although you might think that the sound of moving water and the cool breeze is enough, there's something else you need- a comfortable boat mattress. Aside from providing comfort, it should be designed in a way to handle the distinct environmental factors.

Now, the problem is that there are too many options on the market, which makes choosing the "one" a difficult job. That's why we bring to you the top two boat mattresses worth investing in.

Top 2 Boat Mattresses

1. Emma Comfort Mattress

For starters, we have the Emma Comfort mattress, which has been specifically designed to suit the requirements of Australian sleepers. The durable and high-quality memory foam construction accounts for its longevity as well as comfort.

On top of that, the uniform weight distribution property aids pressure relief by contouring your body shape to provide optimum support to your pressure points. This is primarily made possible by the 25cm-zoned memory foam construction, which keeps the shoulders, spine, and hip aligned.

Moreover, it will maintain its shape and firmness even with regular use and different sleeping styles. Long story short, this Emma Comfort mattress may be your best bet to get a good night's sleep.

On that note, let us take you through the different layers that go into the making of this mattress:

A. Fresh Air Comfort Cover

The topmost layer is a white-coloured fresh air comfort cover that creates the perfect grip to prevent the mattress from sliding around. It's made from a special "climate control" fabric that takes care of humidity and moisture to keep sleepers cool. This feature will come in handy for those hot and humid days on the water. And it has a removable, machine-washable design for easy maintenance.

Besides, this layer is ably supported by a grey bottom that ensures optimum air circulation. Not only will it make your overall sleeping experience more comfortable, but it will also resist the growth of mould and mildew.

B. Airgocell Foam

The second layer is the Airgocell foam layer, which comprises a point-elastic to restrict the effects of motion. This is because the elastic compresses only one area of the mattress, keeping the rest of it intact. So, you can rest assured about sleeping soundly even with a partner who can't lay still.

Much like the top layer, it keeps moisture at bay for maintaining a dry and hygienic sleeping environment. The combination of these two layers makes it ideal for boats, despite being made for interior use.

C. HRX Foam Layer

At the bottom of the mattress is a specialised HRX foam layer that features some high-quality zoning technology. Simply put, it ensures that the mattress always conforms to the sleeper's body shape for providing maximum comfort in any sleeping position.

Apart from that, the open pore surface enhances the breathability of the mattress for better sanitation and comfort on your boat bed.

Weight And Thickness

Now that you have a basic idea about the construction and the different layers, let's look into the different size variations.

  • Single: 188x92x25 cm, weighs 17 kg
  • King Single: 203x107x25 cm, weighs 19 kg
  • Double: 188x138x25 cm, weighs 26 kg
  • Queen: 203x153x25 cm, weighs 29 kg
  • King: 203x183x25 cm, weighs 35 kg


It may be helpful to know that the Emma comfort mattress is one of the brand's premium products, so you may have to stretch your budget. The price breakdown is as follows:

  • Single: $799
  • King Single: $899
  • Double: $999
  • Queen: $1,099
  • King: $1,199

However, the brand offers hefty discounts on special occasions, so keep an eye on the official website. It also offers a solid 10-year warranty and 100-night trial policies. If you don't find it comfortable enough, contact the customer service team within the said time frame to return it for free.

2. New Memory Foam Boat Mattress

If you're looking for a custom-made mattress for your next boat ride, then this product may fit the bill. Its biggest highlight is the use of natural latex, which, unlike Asian latex, doesn't have any fillers or stabilisers.  Hence, buyers don't have to worry about its durability in the long run.

Additionally, the Viscoflex memory foam filling makes it adequately soft to support your pressure points without any overwhelming "sinking" feeling. We liked how the foam density cushions the knees, shoulders, and spine, thereby providing optimum pain relief.

Not only that, but it also works to reduce interface pressure, which means you don't have to constantly twist and turn to find the required comfort. And no matter how cold the temperature is, the mattress won't fail to adhere to the shape of your body.

In hindsight, the Viscoflex memory foam is a specially designed open-cell foam, which provides the mattress with adequate breathability and air circulation. As a result, the material remains cool in different temperatures, which is something that hot sleepers will definitely appreciate.

Besides, it has a dedicated anti-microbial protection layer to prevent the growth of microbes and bacteria. Another advantage is that, unlike imported foam mattresses that may contain harmful chemicals, this Australian-made unit strictly adheres to the standard and safety regulations of the country.


The model we reviewed costs $875, but the price may vary according to the customisations you make. So, don't forget to get in touch with the brand to understand how the exact price is calculated. Plus, buyers get a 28-night comfort guarantee, where the mattress can be returned within the said time for a refund.


It is also possible to buy a thick bit of memory foam from Amazon and do the DIY work by yourself. You can do the work yourself instead of relying on a contractor, which is more affordable. Nevertheless, the issue is that memory foam is not cheap, so if any mistakes are made, you might end up paying a lot.

Why Should You Go For A Foam Mattress On Sea?

At this point, you may be wondering why we have picked only foam mattresses for this guide. And the answer is pretty simple- these mattresses will provide you with all the comfort that you're used to.

So, if you sleep on a memory foam mattress at home, there's no reason why you should part ways with it only because of water. That being said, we understand that the environment or surroundings will influence its performance to a great extent.

For example, one of the top concerns, when you're on the sea, is excessive moisture in the air, which can soften the material and make it prone to damages. However, a mattress made from premium memory (polyurethane) foam prevents it from getting soft over time. It's designed to have a stable supporting base and a more flexible body contouring top.

In fact, this is the reason why most boat seat cushions are made from memory foam.

Furthermore, they come in different sizes and densities to suit different user preferences. And with advancements in manufacturing technologies, even high-density memory foam mattresses have a lightweight design to aid in transportation.

Additionally, they are equipped with proper ventilation features to regulate your body temperature properly- all this without burning a hole in your pocket. Depending on the brand you opt for, the mattresses may come with several years of warranty as well as a return or refund policy.

However, we should also mention that a custom mattress may cost more, as they are usually built with a combination of different types of foam. Apart from that, v berth mattresses may have a bi-fold hinge to provide easy access to the storage space below.

That's why first-time users prefer buying the ready-made variations.

But the good news is that you can customise one the DIY way, and we will help with it in the following section.

How To Customise A Memory Foam Mattress?

Step 1: Remove The Cover

The first step is to remove the cover and keep it somewhere clean. While some mattresses have removable covers (with zippers or ties), others may have non-removable covers.

In that case, pull the cover with one hand and use a sharp knife or cloth scissors to carefully make a cut along one of the edges without damaging the filling. Cut only as much as you need to take out the mattress in one go. This will save time and make the overall process hassle-free.

Step 2: Mark The Dimensions

Just like you'd do for any other DIY customisation project, measure the space where you want to place your mattress. In this regard, measure the head and foot space that will be suitable for the tallest member on board (if possible) with a ruler or measuring tape.

Then, take a marker pen and mark the corresponding areas on the mattress. We will suggest asking for some help to ensure precise measurements. If you plan to use a standard square or rectangular mattress, keep in mind that it should be exactly the same shape as the deck bed (or like a v berth mattress).

But while at it, don't forget to factor in the required thickness, as you wouldn't want the mattress to be too tall. Otherwise, you may end up hurting your head on the deck every time you try to get on top of it.

From what we have seen, most people restrict the thickness of the mattress between 10 and 15 cm, which makes it ideal for serving the dual purposes of sitting and sleeping. And if you're worried about flattening out the mattress too much in the process, you can always use a memory foam topper to make up for the lost thickness.

If you want to reuse the cover, mark the same dimensions on it, then cut and sew as required. You can also install ties or zippers to make the cover removable. However, keep in mind that cutting the mattress may affect its warranty.

Step 3: Cut The Mattress

Place the mattress on a flat surface and start cutting the mattress according to the markings with a sharp knife. You can also use a drywall square as a template to make straight cuts. Make sure that the blade is parallel to the height of the mattress unless you're looking to cut it horizontally, especially for creating unique shapes.

Don't apply excessive pressure on the areas where you're making the cuts, as it may flatten the mattress too much. And that may lead the mattress to change its shape, thereby messing up the measurements.

We'd strongly recommend using a long knife so that you can cut all the way through. Additionally, you may have to put in more effort to cut the base of the mattress, which tends to be harder than the surface.

If you don't have a long knife at hand, make a shallow cut on the surface as the first step and follow it up with a deeper cut to reach all the way to the bottom. You may even have to make multiple cuts when you reach the base of the mattress.

But whatever the case, don't flip the mattress until you have cut more than half of the base. Likewise, try to complete cutting the mattress in one go. Otherwise, you may find it difficult to match the cuts later on.

Step 4: Trim The Edges

Before putting back the cover, trim any uneven edges, preferably with a smaller knife for better precision. If you have used a serrated knife to size the mattress, you may want to get rid of the serrated design so that it fits the cover.

A pro tip: try to trim the edges in one piece, as that may help you convert them into extra pillows, cushions, or small bolsters. The smaller the pieces are, the less are your options of converting them into something useful.

Step 5: Put Back The Cover

As the final step, put back the cover and zip or tie it. Your boat mattress is ready for use!

Final Verdict

Now that you know our top two recommendations, take your time to go through the details once more and see what best suits your needs. After all, a mattress is not something you buy every day.

To sum it up for you, we'd say that the Emma Comfort mattress is a good option for those who want to try their hands on DIY boat mattress making. But if you don't have the time to make the customisations, then the New Memory Foam Boat Mattress is worth considering.

On that note, we will wrap up today's guide. See you next time!
