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

The LHF (Left Hand Facing) diagonal cut off mattress is one of the most common shapes used in caravan, campervan and boat layouts, particularly where space is limited and access around the bed is needed.

The design removes a corner at a clean angle, creating a practical walkway without drastically reducing the overall sleeping area. This is why it’s often associated with “French bed” layouts in leisure vehicles.

It’s a simple shape — but it only works properly when it’s made to the exact dimensions required.

And just as importantly, the bedding needs to match that same diagonal.

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

Replacement Caravan Mattress with Diagonal Cut Off Design

Factory caravan mattresses are rarely a perfect fit, especially in angled bed layouts.

A replacement caravan mattress with a diagonal cut off allows you to:

• Improve access around the foot of the bed
• Fit neatly around furniture and walls
• Maintain a usable sleeping surface
• Avoid overhang or wasted space

Because the cut is straight and precise, it creates space exactly where it’s needed without unnecessary shaping.

Fitted sheets made to match ensure the mattress stays neat and secure.

Custom Campervan Mattress for Angled Bed Layouts

Campervan interiors rely on efficient use of space.

A custom campervan mattress with a diagonal cut off provides a clean, functional solution where a square mattress would restrict movement.

This shape is particularly effective because:

• It opens up tight walkways
• Keeps the majority of the mattress intact
• Avoids overly complex shapes that reduce comfort

Fitted sheets are made alongside the mattress, so everything fits properly from the start.

Made to Measure Boat Mattress for Compact Cabins

Boat cabins often require angled layouts to make the most of limited space.

A made to measure boat mattress with a diagonal cut off allows you to shape the mattress around the cabin while still maintaining a practical sleeping surface.

The straight cut makes it easier to work around bulkheads and storage areas without introducing unnecessary curves or complexity.

Fitted sheets are produced to match the same angle, ensuring a consistent and secure fit.

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 Cut Off Mattresses

This is where most shaped mattresses fall down.

Standard sheets are made for rectangles — not angled corners. They tend to:

• pull tight across the diagonal
• lift at the corner
• come loose during use

Our fitted sheets are designed specifically for diagonal cut off mattresses:

• Cut to follow the exact angled corner
• Made to match your mattress depth
• Stay in place without slipping
• Available in a range of fabrics, including cooling options

This is what makes the mattress practical in everyday use.

Foam Options to Suit Your Comfort

We offer a full range of foam grades to suit different requirements:

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

Each mattress is built to provide consistent support across the full surface, regardless of the cut-off section.
