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

The RHF (Right Hand Facing) diagonal cut off mattress is one of the most widely used shapes for caravan, campervan and boat mattresses, particularly in fixed bed and French bed layouts.

The design removes a corner at a clean angle on the right-hand side, creating usable access around the bed without significantly reducing the sleeping area.

It’s a simple, proven solution — but it only works properly when the mattress is made to the exact shape required.

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

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

Replacement Caravan Mattress for French Bed Layouts

This is the classic replacement caravan mattress shape.

If your current mattress is awkward to move around, overhangs the base or simply doesn’t fit properly, a made to measure diagonal cut off mattress solves the problem properly.

It allows you to:

• Improve access at the foot of the bed
• Fit neatly around walls and furniture
• Maintain a large usable sleeping surface
• Replace poorly fitting factory mattresses

This is why diagonal cut off mattresses are so common in caravan layouts.

Fitted sheets made to match ensure everything stays in place and works as it should.

Custom Campervan Mattress for Angled Bed Designs

Campervan layouts often rely on angled beds to make the most of limited space.

A custom campervan mattress with a right-hand diagonal cut off allows you to:

• Open up tight walkways
• Keep the majority of the mattress intact
• Avoid overcomplicated shapes

It’s a straightforward solution that works in real-world conversions — not something overly engineered.

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

Made to Measure Boat Mattress for Practical Layouts

Boat cabins often require efficient use of space, particularly around fixed beds.

A made to measure boat mattress with a right-hand diagonal cut off allows you to:

• Fit the mattress cleanly within the cabin
• Improve access without sharp corners
• Maintain a comfortable sleeping surface

The angled cut provides a clean, functional solution that works well in confined environments.

Fitted sheets are produced to match the same shape, ensuring a secure and consistent 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 suppliers fall down.

A standard fitted sheet is designed for a rectangle — not an angled corner. It will:

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

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

• Cut to follow the exact right-hand angle
• 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 practical day to day — not just something that fits once.

Foam Options to Suit Your Comfort

We offer a full range of foam grades depending on how the mattress will be used:

• Softer foams for a more cushioned feel
• Medium grades for general 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.
