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

A square rectangle split mattress is designed for caravan, campervan and boat layouts where a standard rectangular mattress needs to be divided into sections for practical use.

The overall shape remains simple — square or rectangular — but the mattress is split into two or more sections, allowing it to be lifted, folded or moved easily.

This is essential in many real-world layouts where access to storage or bed mechanisms is required.

And like all mattresses, it only works properly when the bedding is made to match the configuration.

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

Replacement Caravan Mattress for Lift-Up and Storage Beds

Many caravan beds sit over large storage compartments, making a one-piece mattress heavy and awkward to handle.

A replacement caravan split mattress allows you to:

• Lift one section at a time
• Access storage areas easily
• Maintain a clean, flat sleeping surface
• Avoid removing the entire mattress

Split configurations are widely used in dinette and fixed bed layouts where daily usability matters.

Fitted sheets made to match ensure both sections sit correctly and function as one.

Custom Campervan Mattress for Folding and Rock & Roll Beds

Campervan beds are built to do more than just sleep — they fold, slide and convert.

A custom campervan square or rectangle split mattress is ideal for:

• Rock and roll beds
• Fold-out bed systems
• Sliding or lifting platforms
• Compact layouts with storage underneath

The split design allows the mattress to move with the bed, rather than working against it.

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

Made to Measure Boat Mattress for Sectioned Berths

Boat cabins often use sectional bed bases to maximise space and storage.

A made to measure split rectangle boat mattress allows you to:

• Work across multiple sections
• Maintain access to under-bed storage
• Handle the mattress in manageable pieces

The rectangular base keeps things simple, while the split construction makes it practical in confined spaces.

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 size and layout, we can manufacture both the mattress and fitted sheets to match it precisely.

Made to Measure Fitted Sheets for Split Mattresses

This is where most suppliers fall down.

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

• pull apart at the join
• bunch between sections
• come loose during use

Our fitted sheets are made specifically for split mattresses:

• Designed to work across multiple sections
• Cut to match your exact size and depth
• Stay in place without slipping or separating
• 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 to Suit Everyday Use

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

• Softer foams for comfort
• Medium grades for general use
• Firmer foams for durability and support
• 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.

Why Choose a Square Rectangle Split Mattress?

This design is built for practicality:

• Works with lifting and folding bed bases
• Allows access to storage without removing the mattress
• Maintains a full rectangular sleeping surface
• Ideal for caravan, campervan and boat mattresses
• Designed to work with fitted sheets made to match

It’s the simplest shape — made functional.

Express Service Available

If you need your mattress quickly, we offer an express service on selected orders.

Covers and Finishing Options

Complete your mattress with covers designed for real use:

• Cooling covers for temperature control
• Easy to clean materials for everyday practicality
• Tencel covers for a softer, breathable finish

All covers and fitted sheets are made specifically to suit your mattress size and split configuration.

Mattress and Fitted Sheets Designed Together

A split mattress only works properly when everything is made as one system.

By supplying both the mattress and fitted sheets, you get:

• A precise fit across all sections
• Better usability in real layouts
