Why Boats Need Specialist Mattresses
The marine environment presents unique challenges that standard mattresses simply cannot handle.
Unique Hull-Shaped Berths
Boat berths follow the contours of the hull — curved walls, tapered bow sections, angled corners, and irregular shapes. V-berths, quarter berths, and aft cabins all require precision-cut mattresses that standard rectangles cannot provide.
Marine Environment Challenges
Boats face constant humidity, salt air, and condensation. Standard mattresses absorb moisture, harbour mould, and develop unpleasant odours. Our boat mattresses use breathable, moisture-resistant materials specifically designed for life on the water.
Comfort Despite Constraints
Space is precious on a boat. Our mattresses deliver genuine comfort within the constraints of your vessel — proper support, appropriate thickness, and quality materials that make every night aboard feel like sleeping at home.

Boat Mattress Questions
Everything you need to know about replacement boat mattresses
We manufacture custom replacement mattresses for all types of vessels:
- Narrowboats: Traditional and modern narrowboats of all lengths, including cross-bed and lengthways configurations
- Canal Boats: Widebeam boats, Dutch barges, and all inland waterway vessels
- Yachts: Sailing yachts from trailer sailors to blue water cruisers — all berth types
- Motor Cruisers: Sports cruisers, flybridge boats, and motor yachts
- Catamarans: Sailing and power cats with their unique hull configurations
- Houseboats: Static and cruising houseboats
- RIBs & Day Boats: Cuddy cabins and overnight berths
If it floats and has a bed, we can make a mattress for it. We've worked with everything from 20ft trailer sailors to superyachts.
We make mattresses for every boat sleeping configuration:
- V-Berths: Forward cabin beds that follow the bow shape — often our most complex projects
- Quarter Berths: Aft sleeping areas tucked under cockpits
- Master Cabins: Main sleeping areas in aft or midship positions
- Saloon Conversions: Settees and dinettes that convert to sleeping
- Pilot Berths: Narrow sea berths for passage making
- Forecabin Doubles: Forward double berths with hull curvature
- Bunk Berths: Single berths in crew quarters
- Cross Beds: Narrowboat beds that span the full width
Each berth type has unique challenges — curved hull walls, tapered shapes, limited headroom. We've solved them all.
Boat berths often have the most complex shapes we work with. Here's how to get accurate measurements:
- Template Method: Create a paper or cardboard template of your berth — best for curved hull shapes and V-berths
- Free Template Kit: We can post materials for you to create an accurate template
- Measurement Guide: For simpler rectangular berths, we'll send a diagram showing what measurements we need
- Photo Method: Take photos with a tape measure visible — we'll guide you on angles
- Existing Mattress: If your current mattress fits well, trace around it
For V-berths and curved shapes, the template method gives the best results. Don't worry about getting it perfect — we'll work with you to refine the shape.
Yes — dealing with the marine environment is central to our boat mattress design:
- Breathable foams: Open-cell construction allows air circulation and prevents moisture trapping
- Moisture-wicking covers: Fabrics that draw moisture away from the sleeping surface
- Anti-microbial treatment: Inhibits mould, mildew, and bacterial growth
- Quick-dry properties: Materials that don't hold water if they do get damp
- Ventilation design: Construction that allows air to circulate underneath
We strongly recommend our marine-specific covers for any boat that's used regularly. They make a significant difference to mattress longevity and hygiene.
We offer multiple comfort levels suitable for the marine environment:
- Essential Comfort: High-density foam — excellent value for occasional use and guest berths
- Bodyshape™ Memory Foam: Body-contouring comfort that adapts to your shape — ideal for regular cruising
- CoolPlus™ Cooling: Gel-infused foam for temperature regulation — perfect for warmer climates
- Pocket Spring: Traditional spring support with marine-suitable construction — for those who prefer a bouncier feel
- Imperial Elite™ 2000: Our premium 2000 pocket spring — luxury comfort for liveaboards and serious cruisers
All options can be paired with marine-grade covers for maximum protection against the boat environment.
Yes — V-berths are one of our specialities:
- Complex bow shapes: We replicate the exact taper and curves of your forward cabin
- Hull wall curvature: Mattresses shaped to follow the curve of the hull sides
- Filler pieces: Optional inserts to square off the V for easier sheet fitting
- Two-piece options: Split mattresses for easier handling through companionways
- Chain locker cut-outs: Notches for anchor chain access
- Hatch clearance: Shaped to allow forehatch opening
V-berths are often our most complex projects, but we've made thousands of them. The template method is essential for getting the shape right.
Absolutely — narrowboats are a major part of our business:
- Cross beds: Full-width beds that span the narrowboat beam
- Dinette conversions: Mattresses for seating that converts to sleeping
- Pull-out beds: Beds that extend from seating or storage
- Fixed doubles: Permanent sleeping areas in bow or stern cabins
- Curved hull sides: Shaped to follow the narrowboat's curved walls
- Gunwale cut-outs: Notches for the boat's internal structure
We understand narrowboat living — the need for comfort on extended cruises, the importance of ventilation, and the challenges of the canal environment.
Mould prevention starts with the right mattress and good practices:
- Choose marine materials: Our breathable foams and anti-microbial covers are designed for boat use
- Ensure ventilation: Use a ventilated bed base or moisture barrier underneath
- Air regularly: When possible, lift mattresses to allow air circulation
- Control humidity: Use dehumidifiers or moisture absorbers when the boat is closed up
- Washable covers: Remove and wash covers regularly — our removable covers make this easy
- Don't leave bedding on: Remove duvets and sheets when leaving the boat
A quality boat mattress with proper care will last for years without mould issues. The investment in marine-grade materials pays off.
Yes — saloon conversions are a common request:
- Settee cushions: Comfortable seating that works equally well as sleeping surfaces
- Infill pieces: Sections that fill gaps when converting to a double
- Back cushions: Designed to work as part of the sleeping surface
- Custom shapes: Matching the exact footprint of your saloon
- Matching covers: Coordinated fabrics across all pieces
The key is creating cushions that are firm enough for seating but comfortable enough for sleeping — we've perfected this balance over decades.
