FAQ
What makes a marine mattress different from a standard mattress?
Marine mattresses are designed specifically for high-humidity and confined environments. They use breathable, water-resistant materials that prevent mould and mildew while providing optimal comfort and support for sleeping aboard boats or yachts.
Can a marine mattress be made to fit tight or irregular spaces?
Yes. Every mattress is custom-built to fit your cabin perfectly, even if it has rounded edges, curves, or limited access through doorways. We take accurate measurements to ensure the mattress fits precisely and comfortably in your space.
How should I maintain a marine mattress to keep it in good condition?
Allow airflow under and around your mattress whenever possible, and use a breathable cover to reduce condensation. Air it out between trips and wipe away excess moisture after long voyages. These simple steps help preserve comfort and freshness.
