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

The RHF (Right Hand Facing) twin diagonal cutaway mattress is designed for caravan, campervan and boat layouts where two angled sections need to be removed to create access and maintain balance across the bed.

Unlike a single cutaway, this design features dual diagonal cutaways, typically used in split or twin mattress setups where both sides need to work within tight or restricted layouts.

It’s a practical solution for beds that need to be accessed from more than one side — without compromising the overall sleeping surface.

And like all shaped mattresses, it only works properly when the bedding follows the same profile.

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

Replacement Caravan Mattress with Twin Diagonal Cutaways

Caravan layouts often require access from both sides of the bed, particularly in fixed or island-style configurations.

A replacement caravan mattress with twin diagonal cutaways allows you to:

• Improve access on both sides of the bed
• Fit cleanly within restricted layouts
• Maintain a balanced sleeping surface
• Avoid awkward overhang or wasted space

This is especially useful where a single cutaway does not provide enough clearance.

Fitted sheets made to match ensure everything stays neat, secure and usable.

Custom Campervan Mattress for Twin and Split Bed Layouts

Campervan beds are rarely straightforward.

A custom campervan mattress with twin diagonal cutaways is ideal where:

• The bed is split into sections
• Access is required from both sides
• Layouts are symmetrical or mirrored
• Space is tight but needs to remain usable

This design improves day-to-day usability across the full bed — not just one side.

Fitted sheets are made alongside the mattress, ensuring everything works together properly from the start.

Made to Measure Boat Mattress for Dual Access Cabins

Boat cabins often require clever layouts to maximise space and usability.

A made to measure boat mattress with twin diagonal cutaways allows you to:

• Improve movement within confined cabins
• Fit around structural features on both sides
• Maintain a practical sleeping surface

The dual cutaway design provides a clean, balanced solution that works in real marine environments.

Fitted sheets are produced to match the same configuration, ensuring a secure fit in use.

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 Twin Cutaway Mattresses

This is where most suppliers fall short.

Standard fitted sheets are not designed for dual cutaway shapes. They tend to:

• pull unevenly across both angled sections
• lift at the edges
• come loose during use

Our fitted sheets are made specifically for twin diagonal cutaway mattresses:

• Cut to follow both diagonal cutaways
• 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 for Balanced Support

With a twin cutaway design, balance is critical.

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

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

Each mattress is built to provide consistent support across both sides, ensuring the shape does not compromise comfort.
