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

A square or rectangle mattress is the most widely used mattress shape for caravan, campervan and boat beds, forming the starting point for almost all layouts.

Whether you’re replacing a worn-out mattress or upgrading comfort, this design provides a clean, full sleeping surface with no cut-outs or shaping, made precisely to fit your bed base.

It may be the simplest shape — but it’s also the one that needs to be right.

And like all mattresses, it only performs properly when the bedding fits correctly.

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

Replacement Caravan Mattress – The Standard That Actually Fits

Most factory caravan mattresses are built to a price, not to fit properly.

A replacement caravan square or rectangle mattress allows you to:

• Match the exact bed base dimensions
• Improve comfort and support
• Replace tired or poorly fitting originals
• Upgrade materials and covers

Because caravan bed sizes are rarely standard, a made to measure approach ensures a proper fit rather than forcing a domestic size into place.

Fitted sheets made to match complete the setup and keep everything in place.

Custom Campervan Mattress for Fixed and Rock & Roll Beds

Campervan beds vary massively in size and layout, but many are still based on a rectangular footprint.

A custom campervan square or rectangle mattress is ideal for:

• Rock and roll beds
• Fixed rear beds
• Slide-out or fold-out platforms
• Pop-top sleeping areas

This shape keeps things simple — providing maximum usable sleeping area without unnecessary shaping.

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

Made to Measure Boat Mattress for Berths and Cabins

Boat berths are often rectangular at their core, even when surrounded by shaped areas.

A made to measure square or rectangle boat mattress allows you to:

• Fit cleanly within berth spaces
• Maintain full sleeping width
• Create a comfortable, usable base mattress

This is often the starting point before adding any additional shaping if required.

Fitted sheets are produced to match the exact size, ensuring a secure fit in real marine conditions.

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

Made to Measure Fitted Sheets for Square and Rectangle Mattresses

Even with a simple shape, fit matters.

Standard sheets are often too loose or too tight, especially in caravan and campervan sizes. They can:

• bunch up during use
• come loose at the corners
• wear unevenly

Our fitted sheets are made specifically for your mattress:

• Cut to the exact length, width and depth
• Designed to stay in place
• Available in a range of fabrics, including cooling options
• Built for real-world use

This is what makes the mattress work properly day to day.

Foam Options to Suit Every 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 support and durability
• Memory foam options for pressure relief

Each mattress is built to provide consistent support across the full surface.

Why Choose a Square Rectangle Mattress?

This shape is the foundation of most layouts:

• Full, uninterrupted sleeping surface
• Fits the majority of caravan, campervan and boat beds
• Ideal for replacement mattresses
• Can be made to any size
• Designed to work with fitted sheets made to match

It’s the simplest option — and often the best one.

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.

Mattress and Fitted Sheets Designed Together

A mattress performs best when everything is made as one system.

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

• A precise fit
• Better usability
• A cleaner finish
