Split D Island Mattress for Caravan, Campervan & Boat – Made to Measure with Fitted Sheets

A split D island mattress is designed for caravan, campervan and boat layouts where a central island bed requires both full access around the foot end and the ability to lift or move the mattress in sections.

This design combines a full-width D-shaped curved foot end with a split construction, allowing the mattress to be lifted, folded or handled in two sections rather than one large piece.

It’s the practical solution for island beds that need to function properly — not just fit the space.

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

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

Replacement Caravan Split Island Mattress with D Shaped Foot End

Many caravan island beds are built over storage areas, making a one-piece mattress heavy and awkward to lift.

A replacement caravan split D island mattress allows you to:

• Lift one section at a time for easier access
• Maintain full walk-around access at the foot of the bed
• Fit neatly to the bed base with no gaps
• Avoid the hassle of handling a full-size mattress

This is the correct setup for modern caravan island beds that need both access and usability.

Fitted sheets made to match ensure both sections sit properly and work together as one.

Custom Campervan Mattress for Central Split Bed Layouts

Campervan layouts often combine compact space with clever storage solutions.

A custom campervan split D island mattress is ideal where:

• The bed base lifts for storage
• The mattress needs to be handled in sections
• A central bed layout requires access on both sides

The D-shaped end improves movement around the bed, while the split design makes it practical to use day to day.

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

Made to Measure Boat Mattress for Island Bed Cabins

Boat cabins often use island-style beds to maximise comfort in confined spaces.

A made to measure split D island boat mattress allows you to:

• Access storage areas beneath the bed
• Improve movement around the foot end
• Handle the mattress in manageable sections

The split construction is particularly useful in marine environments, where space is limited and flexibility is essential.

Fitted sheets are produced to match the same configuration, ensuring a secure fit in real 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 and layout, we can manufacture both the mattress and fitted sheets to match it precisely.

Made to Measure Fitted Sheets for Split Island Mattresses

This is where most suppliers fall down.

Standard fitted sheets are not designed for split mattresses with curved ends. They tend to:

• pull unevenly across both sections
• lift along the split
• come loose during use

Our fitted sheets are made specifically for split D island mattresses:

• Cut to follow the full curved foot end
• Designed to work across split 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 practical day to day.

Foam Options for Split Mattress Use

With a split mattress, weight and usability matter just as much as comfort.

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

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

Each section is built to provide consistent support across the full sleeping surface, even where the mattress is divided.
