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

A D shape island mattress is the go-to solution for caravan, campervan and boat island bed layouts, where access around the foot of the bed is essential.

The full curved end removes the hard corners found on standard mattresses, making it far easier to move around the bed in tight spaces without reducing the usable sleeping area.

This is why D shape island mattresses are widely used as replacement caravan mattresses, campervan mattresses and boat mattresses where factory options simply don’t fit properly or deliver the comfort required.

And here’s the part most suppliers ignore —
a shaped mattress needs fitted sheets made to the same shape, or it simply doesn’t work properly.

We supply both.

Replacement Caravan Island Bed Mattress Made to Measure

If you’re replacing a caravan mattress, chances are the original never fitted properly to begin with.

Our replacement caravan island bed mattresses are made to measure to match your exact layout, including the full D-shaped foot end. This gives you:

• A proper fit to your caravan bed base
• Easier access around the foot of the bed
• Improved comfort compared to standard foam
• No overhang, no gaps, no compromise

Add fitted sheets made to the same shape, and the whole setup works as it should — neat, secure and practical.

Custom Campervan Mattress for Island Bed Layouts

A custom campervan mattress needs to make the most of limited space without feeling restrictive.

The D shape design allows you to maintain a usable sleeping surface while opening up the walkway at the foot of the bed — something that makes a real difference in everyday use.

We manufacture each campervan mattress to your exact requirements, ensuring it fits your layout rather than forcing you to adapt to a standard size.

Fitted sheets are produced alongside the mattress, so everything fits together properly from day one.

Made to Measure Boat Mattress for Island Bed Cabins

Boat cabins often require clever use of space, particularly where access is needed at the foot of the bed.

A made to measure boat mattress in a D shape provides that access cleanly, without introducing awkward angles or reducing comfort.

The curved profile improves movement within the cabin while maintaining a proper sleeping surface — ideal for both occasional use and extended stays onboard.

With fitted sheets made to match, the mattress stays secure and usable in real marine conditions.

Made to Measure – Sizes, Templates or Drawings

Every mattress is made to order.

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 the mattress and fitted sheets to match it precisely.

Made to Measure Fitted Sheets for D Shape Island Mattresses

This is where we stand apart.

A standard fitted sheet will not work on a D shape island mattress. It will pull across the curve, lift at the edges and come loose almost immediately.

Our made to measure fitted sheets are designed specifically for D shape island mattresses:

• Cut to follow the full curved foot end
• Made to match your mattress depth
• Stay in place without slipping or bunching
• Available in a range of fabrics, including cooling options

The result is a proper fit that looks right and stays put.

Foam Grades to Suit Your Comfort

We offer a range of foam options to suit different needs and preferences:

• Softer foams for a more cushioned feel
• Medium grades for everyday comfort
• Firmer foams for support and durability
• Memory foam options for pressure relief

Each mattress is built to provide consistent support across the full surface, including the curved section.
