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

A square rectangle twin cutaway mattress is designed for caravan, campervan and boat layouts where two sections need to be removed from a standard rectangular mattress to fit around fixed features.

Unlike diagonal or curved shapes, this design uses two defined cutaways within a square or rectangular footprint, allowing the mattress to work around furniture, structures or restricted areas while still maintaining a strong, usable central sleeping surface.

It’s a practical solution for layouts that require more than a simple adjustment, but don’t need angled or curved shaping.

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 Cutaway Sections

Caravan bed layouts are often influenced by surrounding furniture such as wardrobes, cupboards or side units.

A replacement caravan square rectangle twin cutaway mattress allows you to:

• Remove two sections to clear fixed obstacles
• Fit accurately within restricted layouts
• Maintain a central sleeping area
• Avoid forcing a standard mattress into place

This is particularly useful where a single cutaway is not enough to achieve a proper fit.

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

Custom Campervan Mattress for Practical Layouts

Campervan interiors often combine compact design with fixed structures that interrupt a standard mattress shape.

A custom campervan twin cutaway mattress is ideal where:

• Multiple obstructions affect the bed space
• Layouts require square or rectangular cut sections
• You want a simple, functional solution without angled cuts

This approach allows you to adapt the mattress to the layout without overcomplicating the design.

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

Made to Measure Boat Mattress for Complex Cabin Spaces

Boat cabins frequently require custom mattress shapes to work around bulkheads, storage and structural features.

A made to measure square rectangle twin cutaway boat mattress allows you to:

• Remove two defined sections for clearance
• Fit within non-standard cabin layouts
• Maintain a practical and comfortable sleeping surface

The twin cutaway design provides a clean, structured way to adapt a rectangular mattress to complex spaces.

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

Standard sheets are designed for rectangles — not cutaway shapes. They tend to:

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

Our fitted sheets are made specifically for twin cutaway mattresses:

• Cut to follow both cutaway sections
• 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 once.

Foam Options Built for Consistent Support

Even with two sections removed, 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 general use
• Firmer foams for durability and structure
• Memory foam options for pressure relief

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