How to measure for a custom boat mattress

Key Definitions

Base: The part of the mattress that sits on the bed deck or support (like plywood or slats).
Top: The surface you sleep on.
Head and Foot: The head is where your head rests when lying down; the foot is where your feet go.
Beveled Edges: Mattresses with angled sides, where the measurements of the top and base differ because the mattress isn’t a perfect rectagle. 

Measuring Guidelines

1. Gather Tools: Use a flexible tape measure and have a notepad to record measurements.
2. Measure Length and Width: Measure the maximum length and width of the space or existing mattress, noting any differences between the top and base.
3. Determine Thickness: Decide on the desired mattress height, considering any existing mattress or space limitations.
4. Identify Shape: Note if the mattress is rectangular, a V-berth, or another unique shape, accounting for curves or angles.
5. Check for Beveled Edges: If sides are angled, measure both the top and base dimensions.
6. Consider Height Restrictions: Be aware of any overhead obstructions like low ceilings or cabinets that may limit mattress thickness.
7. Note Special Features: Record any cut-outs, notches, or accommodations needed for fixtures like poles or rails.
8. Decide on Accessibility: Determine if the mattress should be made in sections for easy installation and removal.
9. Use Boat Schematics: Refer to templates or diagrams from your boat’s manufacturer if available.
10. Double-Check Measurements: Verify all measurements at least twice to ensure accuracy—custom mattresses cannot be returned due to measurement errors.

FAQs

Q: How much does a v-berth boat mattress cost?

The cost of a V-berth boat mattress can vary quite a bit based on factors like size, materials, and customization options. On average, you might expect to spend anywhere from $500 to $2,000 for a quality custom mattress. The price depends on the type of foam or material you choose (like memory foam or latex), the fabric covering, and any additional features such as moisture resistance or antimicrobial properties. To get an accurate idea of the cost, it’s best to request a personalized quote based on your specific needs and preferences.

Q: What are boat mattress sizes?

Boat mattresses come in a wide variety of shapes and sizes to fit the unique spaces aboard different vessels. Unlike standard home mattresses, boat mattresses often need to be custom-made to accommodate irregular dimensions, curved walls, or the distinctive V-shape of a bow berth. Common shapes include rectangular, V-berth, and tapered mattresses. Since there’s no standard sizing in the boating world, it’s important to measure your sleeping area carefully. Many manufacturers offer guidance on how to take accurate measurements or can assist you in creating a template to ensure a perfect fit.

Q: How thick should a boat mattress be?

The ideal thickness for a boat mattress depends on your comfort preferences and the space constraints of your cabin. Generally, boat mattresses range from 4 to 8 inches thick. If headroom is limited, you might opt for a thinner mattress. However, for enhanced comfort—especially during longer stays—a thicker mattress around 6 inches can provide better support and cushioning. Remember to balance comfort with practicality, ensuring the mattress fits well within your boat’s sleeping area without making the space feel cramped.

Q: What is the best foam for a boat mattress?

Selecting the best foam for your boat mattress involves considering both comfort and the marine environment. Latex foam is a popular choice because it’s naturally resistant to moisture, mold, and mildew—important factors when you’re on the water. Memory foam offers excellent comfort and pressure relief but can absorb moisture unless it’s specially treated or paired with moisture-resistant layers. High-density polyurethane foam is another good option, offering durability and support. Some boat owners prefer a hybrid approach, combining different foams—like a supportive base layer topped with a softer foam—for the best of both worlds. Whichever material you choose, make sure it’s suited to withstand the unique conditions of life afloat.
