Description

V Berth Cutaway Mattress – Made to Measure for Boats & Yachts

This V berth cutaway mattress is made to measure for your exact boat layout, designed for cabins where a standard V berth shape does not fit due to restricted space or access requirements.

Built as a single-piece mattress with a defined cutaway section, this design allows the mattress to fit around cabin features while maintaining a continuous sleeping surface.

Each mattress is precision cut to your measurements, ensuring a clean, accurate fit within your berth.

📏 When to Choose a Cutaway V Berth Mattress

A cutaway V berth mattress is the right option when a standard V berth will not fit properly.

It is commonly used where:

  • A corner needs to be removed for access
  • The berth sits against an angled or offset cabin wall
  • Walkway space needs to be created
  • Fixed furniture or structures restrict the mattress shape

👉 This allows you to improve access without losing the full mattress surface.

⚠️ When This Is NOT the Right Option

This option may not be suitable if:

  • Your berth is a standard V shape with no obstruction
  • You require multiple sections for lifting or access
  • You need more flexibility across the berth

In those cases:

  • A standard V berth mattress is the simplest option
  • A multi-part configuration may be better for access

🔄 Built for Awkward & Restricted Layouts

The key advantage of a cutaway mattress is its ability to adapt to real-world cabin constraints.

It allows you to:

  • Fit around structural features
  • Improve movement around the berth
  • Maintain a continuous sleeping surface
  • Avoid over-complicating the layout with multiple sections

👉 It’s a practical solution for non-standard spaces.

🧩 Made to Measure for Your Exact Berth

Every mattress is cut to your exact layout.

You can provide:

  • Full berth dimensions
  • Specific cutaway measurements
  • Templates for complex shapes

This ensures the mattress fits precisely and functions as intended.

🧠 Foam Options

The right foam depends on how your berth is used.

High Density Reflex Foam
Firm, durable and ideal for regular onboard use.

Memory Foam (SFV50 Premium Grade)
Improves comfort and reduces pressure points.

GelFlex Foam
Helps regulate temperature and improve airflow in enclosed cabins.

🛏️ Covers & Finishing

Each mattress is supplied with a removable cover, tailored to the cutaway shape to ensure a clean and consistent fit.

💧 Managing Condensation

Boat cabins are prone to moisture build-up, particularly in shaped berths.

Using a breathable spacer beneath the mattress helps improve airflow and reduce condensation over time.

➕ Optional Add-Ons

You can complete your setup with:

  • Mattress toppers
  • Custom fitted sheets
  • Replacement covers

🇬🇧 Made to Measure in the UK

Every mattress is handcrafted in the UK and built to your exact specification, ensuring a precise fit and long-lasting performance.
