Split D Shape Island Mattress – Made to Measure in the UK

If your caravan, campervan or boat has a D-shaped island bed with a split base, you’ll already know the problem — nothing off-the-shelf fits properly.

Standard mattresses don’t match the curve.
One-piece mattresses don’t work with lift-up bases.
And poor-quality foam quickly becomes uncomfortable.

This split D shape island mattress is made to measure, designed to match both the curved front edge and the split base — giving you proper support, a precise fit, and a noticeable improvement in comfort.

Designed for Split Island Bed Layouts

This shape is commonly found in:

• caravan island beds
• motorhome rear bedrooms
• boat cabins with lift-up access
• custom campervan layouts

The design combines:

• a curved D-shaped front for access and movement
• a split construction for lifting, storage and flexibility

Standard mattresses simply don’t work in these setups.

Our solution:

• made to your exact measurements
• split to match your base sections
• shaped to follow the curve precisely

Two Sections – One Proper Mattress

This mattress is supplied in separate sections to match your base.

That means:

• easy lifting for storage access
• no bending or forcing a one-piece mattress
• better handling in tight spaces
• proper alignment when laid flat

When in use, both sections sit together to form a comfortable, continuous sleep surface.

Built for Proper Support – Not Just Comfort

Unlike toppers, this is a full mattress designed to provide:

• proper support across the entire surface
• long-term durability
• improved sleep quality night after night

This is the right solution when your existing mattress is:

• worn out
• sagging
• lacking support
• beyond what a topper can fix

Foam Options to Suit Your Comfort

We offer a range of foam grades depending on your needs:

• firmer support foams for structure
• medium options for balanced comfort
• memory foam combinations for pressure relief

This allows you to build a mattress that suits how you actually sleep — not just what was fitted originally.

Cooling Covers That Make a Real Difference

Heat build-up is a common issue in caravans, campervans and boats.

That’s why we offer:

Tencel Cooling Cover (Premium)

• breathable natural fibre
• moisture-wicking
• helps regulate temperature
• ideal for enclosed sleeping spaces

Cooltech Cover (Practical Option)

• promotes airflow
• reduces heat retention
• durable and cost-effective

A proper cover makes a noticeable difference — especially in summer.

Complete Your Setup Properly

To finish the setup, you can also add:

• Tencel pillows for cooler, more comfortable sleep
• custom fitted sheets made to match your mattress shape
• mattress toppers for added comfort

This gives you a complete, properly matched sleep system.

Hand Made to Order – Not Off the Shelf

Every split D shape mattress is:

• made to order
• cut to your exact dimensions
• manufactured in the UK
• built using high-quality foam

These are not mass-produced boxed mattresses.

They are built specifically for your layout, ensuring proper fit, comfort and long-term performance.

Flexible Lead Times to Suit Your Plans

We offer:

• standard production lead times
• foam-only options where applicable
• express service when required

Designed for Caravans, Campervans & Boats

This mattress is ideal for:

It’s built specifically for these environments — not adapted from standard bedroom mattresses.

Start with the Right Foundation

If your current mattress is no longer comfortable, replacing it is the most effective upgrade you can make.

A properly fitted mattress provides the support — then you can add comfort layers if needed.
