Choose the Boat Mattress that Fits You.

Owning a boat is a lifestyle. Time spent on your boat is filled with friends, family and good times that create life long memories. Sleeping on your boat should be a natural extension of a great day on the water. When you have a custom-built boat mattress from Portland Boat Mattress, you’ll love sleeping on your boat … you may even prefer it over your bed at home!


In three easy steps, you will be closer to experiencing a truly comfortable night’s sleep on your boat. First, measure your current mattress to determine the right size to order (small, medium or large) for your berth.

Second, choose the mattress that fits your preferred comfort. The last step is to customize your mattress for a plush or firmer mattress. 

Do you need to access storage under your mattress? Just let us know. A hinge can be added at no additional charge for easy access.   

We stand by every mattress we make with our Perfect Fit Guarantee, so you can feel confident your mattress from Portland Boat Mattress will fit your berth perfectly.
