LHF Diagonal Cutaway Mattress for Caravan, Campervan & Boat – Made to Measure with Fitted Sheets

The LHF (Left Hand Facing) diagonal cutaway mattress is designed for caravan, campervan and boat layouts where a simple angled cut is not enough to clear the space required.

Instead of just trimming a corner, this shape removes a larger diagonal section, allowing the mattress to fit around fixed obstacles such as cupboards, bulkheads, steps or structural features.

This makes it a practical solution where standard mattresses — or even basic cut-offs — simply don’t work.

And like all shaped mattresses, it only works properly when both the mattress and the bedding follow the same profile.

That’s why we supply both the mattress and fitted sheets made to match.

Replacement Caravan Mattress with Diagonal Cutaway for Fixed Obstructions

Caravan bed layouts are often dictated by surrounding furniture, not comfort.

A replacement caravan mattress with a diagonal cutaway allows you to:

• Remove a larger section to clear wardrobes or units
• Improve access in restricted layouts
• Fit the bed base properly without forcing a standard shape
• Maintain as much usable sleeping space as possible

This is a more functional solution than a diagonal cut-off, where additional clearance is needed.

Matched fitted sheets ensure the mattress remains neat, secure and practical.

Custom Campervan Mattress for Complex Layouts

Campervan conversions often involve structural features that standard mattresses can’t accommodate.

A custom campervan mattress with a diagonal cutaway allows you to shape the mattress around these features while keeping the remaining surface usable for sleeping.

This approach is particularly useful where:

• Wheel arches or units restrict space
• Drop-down beds require clearance
• Layouts vary between conversions

Fitted sheets are made alongside the mattress, ensuring everything fits together properly from day one.

Made to Measure Boat Mattress for Practical Fit in Confined Cabins

Boat interiors often require more aggressive shaping to make the space usable.

A made to measure boat mattress with a diagonal cutaway allows you to work around bulkheads, storage areas and restricted access points while maintaining a functional sleeping surface.

The diagonal removal provides a clean, efficient way to create space without introducing unnecessary complexity.

Fitted sheets are produced to match the same shape, ensuring a secure fit in real marine conditions.

Made to Measure – Sizes, Templates or Drawings

Every mattress is made to order — nothing off the shelf.

You can provide your requirements in whichever way suits you:

• Standard sizes
• Exact measurements
• Full-size templates
• Drawings or sketches

If you can show us the shape, we can manufacture both the mattress and fitted sheets to match it precisely.

Made to Measure Fitted Sheets for Diagonal Cutaway Mattresses

This is where most suppliers fall down.

A standard sheet cannot cope with a diagonal cutaway. It will:

• pull unevenly across the removed section
• lift at the edges
• come loose during use

Our fitted sheets are designed specifically for this shape:

• Cut to follow the full diagonal cutaway profile
• Made to match your mattress depth
• Stay in place without slipping or bunching
• Available in a range of fabrics, including cooling options

This is what makes the mattress usable day to day — not just something that fits on paper.

Foam Options Built for Consistent Support

Even with a larger cutaway, the mattress still needs to perform properly.

We offer a range of foam grades to suit different needs:

• Softer foams for comfort
• Medium grades for everyday use
• Firmer foams for durability and structure
• Memory foam for pressure relief

Each mattress is built to maintain consistent support across the remaining surface, ensuring comfort is not compromised by the shape.

Why Choose a Diagonal Cutaway Mattress?

This shape is designed for more demanding layouts:

• Removes a larger section to clear fixed obstacles
• Provides more space than a diagonal cut-off
• Maintains a practical sleeping surface
• Ideal for caravan, campervan and boat mattresses
• Works with fitted sheets made to match

It’s a straightforward, functional solution where simpler shapes aren’t enough.
