Replacement Mattress for Boats

Sleeping quarters on a yacht, sailboat or other vessel have unique requirements. Beds for boats must fit in a tight area with limits on size, shape and thickness. They also must be constructed from marine-grade materials that can handle water and salt exposure without sagging, molding and other permanent damage.

We can help you design and customize a V-berth or boat mattress that will offer years of comfort and deep sleep. The thickness of a boat mattress is often restricted to 4–6" (10–15 cm) and will often serve the dual purposes of sleeping and sitting. Therefore, the best performing and most comfortable option involves the combination of a firm, supportive base layer that is usually 3" (8 cm) topped with a comfort layer of 2–3" of higher quality softer foam. At your request, we will bond the layers together to prevent shifting.

Custom Boat Beds

A FoamOrder.com boat V-berth mattress or standard-size mattress is made to order from a variety of high-grade materials. Select a boat mattress shape above — we have more than 20 options and can do custom mattress configurations too. Another way to freshen up your seaside sleeping is with a V-berth mattress topper. We can add a topper to a new mattress or create one to rejuvenate a current mattress.

All marine mattresses should have a cover to help protect them from the elements and microbes. We offer a wide range of custom fabric V-berth boat mattress covers. These include a 40/60 cotton-poly blend, organic materials and our great-looking and durable Sunbrella® lineup. The FoamOrder.com customer service team is happy to assist with your mattress needs — call Monday–Friday, use online chat or send a message with our Contact Form.

Many boat cushions do not require a pattern if they match one of the shapes above. However, if you want us to design a V-berth mattress to fit your boat, you will need to prepare a pattern for us to work from. Take a minute and review how your existing cushions look. This is your chance to correct any gaps and make improvements. Using pattern paper or fabric, simply cut the pattern to the exact size desired. A pattern drawn with precision will result in a more exact-fitting cushion. Please indicate the top of the pattern by writing “This side up.” Indicate which side(s) should be used for zipper placement and stripe direction. Large V-berths and cushions should have a zipper on three sides to make it easier to insert the foam cushion. We recommend placing the zipper on the side facing the boat hull — not under the cushion. This placement hides the zipper from view and prevents it from buckling.

To place an order, all you need are the largest dimensions (thickness, length and width) of your old boat mattress or custom shape. Enter the dimensions after selecting the Pattern Shapes custom option.

What kind of material is best for a V-Berth or boat mattress?

You can select from genuine PostureSense™ memory foam; 100% natural latex, an all-natural foam used in our organic mattresses; or our traditional sailboat mattress foam. For a simple traditional foam boat mattress, we recommend our high-resiliency (HR) EverFlex™ foam if you’re going to spend more than 2–3 nights at a time on this boat mattress. If not, you can get away with our less-expensive (and less dense) EconoFlex™ foam. We offer three firmness options for each of these and generally recommend medium V44 as long as your boat mattress is between 3–5 inches thick. If it’s thicker you should consider our less firm V34, and if it’s less than three inches, you’ll probably want our firmer V54 foam.

Your second boat mattress foam option is our dreamy premium — and organic — latex foam. We offer six firmness options to match your personal sleeping preference from soft to firm. Finally, we offer memory foam boat mattress options as well. However, we always recommend that you put a base layer of polyurethane foam below 1–2 inches of memory foam. Using memory foam boat mattresses by themselves can lead to “bottoming out” where the mattress won’t support the weight of the person lying on it. If you have any questions about how to construct the optimal boat mattress for your vessel, don’t hesitate to contact our customer service team.

Do you make V-berth boat mattress toppers?

If your V-berth boat mattress is too hard or just old and in need of some upgrading, try one of our high-quality comfortable foam toppers. We can customize any standard-sized mattress topper for an extra $10–25 labor (simply make this request by using the “Add Comments” link found in the shopping cart). The cut-to-size option is important since it is often less expensive to order standard-sized foam that is cut down to size. This particularly applies to our natural latex foam and memory foam toppers. If you are unsure of the best option, please contact us. We are happy to help you create the most economical boat mattress solution.

Can you make a hinged V-berth boat mattress?

Boat mattress V-berths often need a hinge to allow easy access to the storage below. Our bi-fold hinge mattress provides a simple solution. The more luxurious hinge option is a quilted top that covers the split in the foam beneath. Our customer service team can help you figure out any issues about creating a custom pattern (including with a bevel cut), how to measure or where to put the hinge.

How do I create a beveled V-berth boat mattress pattern?

Beveled Sailboat Mattress

We can bevel the edge of your v-berth boat mattress to match the contour of your boat. There are two options of beveled marine mattresses.

  • It’s best to send us a pattern of the top and bottom templates. This can be done on the same pattern. Cut the pattern to the top curve and just mark the bottom curve.
  • You also can send us just the bottom pattern with simple instructions for the top. For example, “add three inches to the beveled side for the top pattern.”

If we’re making new covers for your beveled V-berth boat mattress, we know what to do to make the finished product right. If you do not require a new cover, there are a few tricks to replacing the foam properly.

  • Add a comment to your order to “add one inch to the foam bevel edge.” This will help stretch the fabric tight. This is only added to the top of the beveled edge. (This is not needed if you have Dacron on the top.)
  • Add 1" to your actual pattern as we’ll cut it to the pattern exactly.

Failure to do either of these will leave unwanted wrinkles in a fabric such as Sunbrella®.

Boat Mattress Maintenance

Boat interiors are frequently moist. This moisture gets trapped between your mattress and the platform below. To help avoid problems with mold or mildew, air your mattresses or cushions outside in the sun every couple of days, but don’t remove the covers.

When you are not using your boat, store your mattresses vertically in the aisle. For added protection, you can sprinkle an anti-fungal powder on the platforms below your boat mattress as well as on the bottom side of your marine mattress. This is found at most drug stores and is used to treat conditions like athlete’s foot.

Other Notes About Boat Mattresses

  • Marine mattress material should be of high quality to ensure a restful night’s sleep after a long day on the water and to maximize the enjoyment of your boat.
  • A V-berth mattress has the shape of a “V” and is used as a boat mattress to take advantage of often limited sleeping space. V-berth mattresses also often double as rest or sitting areas when not used for sleeping.
  • Ventilate your marine mattress regularly to prevent mold. We recommend adding boat mattress polyester batting to the bottom side of the marine mattress to allow for maximum breathability.
  • Cover the V-berth mattress foam in your marine mattress to protect it. We recommend Sunbrella® fabrics for their great combination of durability, effectiveness and comfort for outdoor or marine applications.
  • Using high-quality polyurethane, memory foam or latex foam in your marine mattress will prevent it from softening over time. All our sailboat mattress options are free of harmful flame retardants and other chemicals. We also custom-sew mattress covers and mattress protectors for any shape of sailboat mattress. We warrant our marine mattress according to the quality of foam used and the fabric chosen.

What Our Customers Are Saying About FoamOrder

Finally, some relief from a very bad back
“I had ordered several mattresses from various companies on the internet over the past several years, and finally, I got a good reference from my sister who had just received one of your mattresses. I thought I had found better deals with the mattresses I was using, but it didn't take long before I realized the "memory foam mattresses all had a memory for the dip in the middle. It was impossible for me to get any comfort, even with expensive mattress toppers. I hadn't had a full night's sleep in almost ten years! When my sister told me about FOAMORDER, I gambled and placed an order for one of your dense foam mattresses. To my great relief (literally), your mattress arrived very quickly, and for the first time since some agonizing spinal fusion surgery, I slept all night long without having to reach for pain pills in the middle of the night. I want to thank you for having the real deal when it comes to dense foam mattresses.”

Good decision - great service.
“I currently sleep on a layered latex mattress I bought from a different mattress supplier. I wanted to replace the top 3 inch layer of talalay (soft density) as it wasn’t comfortable. I’ve been sleeping on it for two years and just couldn’t get comfortable. I couldn’t tell if I was sinking to the bottom or it was just still too firm even though it was Labeled soft. I’ve been wanting to try the egg crate latex topper and finally ordered one a few weeks ago. Since I sleep on a split king (inside only) mattress, I ordered a twin x-long Eggcrate and a twin 1” slab of dunlop to replace the 3” slab of talalay. I arranged the eggcrate pointy side down and the 1” slab underneath it. The height was perfect. All I can say is WOW - what a major difference! No more pain and numbness. No more tossing and turning. I feel well rested for the first time in years. I’m embarrassed that i didn’t try this sooner. I spoke to customer service before I place the order asking about the shipping times. I was assured that it was in stock would arrive at my home in two weeks time. It actually arrived in eight days in good condition. This is my second order with foam order, the first of which were pillows that I returned. The return was very easy and quick, no questions asked. I would definitely order more from foam order in the future and I would definitely recommend them to a friend. Great experience both times.”

Excellent latex foam
“Very professional from start to finish. Glad that I was advised to switch to organic latex. Company was very flexible in handling my custom made cut to an Asian King size bed. Price is very reasonable for the quality of the latex foam and organic cotton cover.”
