RHF Diagonal Cut Off Rounded Corner Mattress for Caravan, Campervan & Boat – Made to Measure with Fitted Sheets

The RHF (Right Hand Facing) diagonal cut off rounded corner mattress is designed for caravan, campervan and boat layouts where access is needed on the right-hand side, but a sharp angled corner would be uncomfortable or intrusive.

This shape combines a clean diagonal cut for space with a rounded corner for comfort, allowing the mattress to fit around furniture, walls and walkways while still feeling natural to sleep on.

It’s a refined version of the standard diagonal cut-off — offering the same practical benefits, but with a more usable finish where it matters most.

And like all shaped mattresses, it only works properly when both the mattress and bedding follow the same profile.

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

Replacement Caravan Mattress for French Bed Layouts with Rounded Corner

This is a common upgrade for caravan beds where a standard diagonal cut feels too harsh in everyday use.

A replacement caravan mattress with a right-hand diagonal cut off and rounded corner allows you to:

• Improve access around the foot of the bed
• Remove a corner without a sharp edge
• Fit properly within the bed base
• Maintain a comfortable sleeping surface

The rounded section makes a noticeable difference when getting in and out of bed — particularly in tighter layouts.

Fitted sheets made to match ensure everything stays neat and secure.

Custom Campervan Mattress for Practical and Comfortable Access

Campervan layouts demand efficiency, but comfort still matters.

A custom campervan mattress with a right-hand diagonal cut off and rounded corner gives you:

• Clearance where you need it
• A softer edge in high-contact areas
• A better balance between space and usability

Compared to a standard diagonal cut, the rounded corner removes the “hard edge” feel, making the bed easier to live with day to day.

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

Made to Measure Boat Mattress for Confined Cabins

Boat cabins often require shaped mattresses to work around bulkheads and restricted access points.

A made to measure boat mattress with a right-hand diagonal cut off and rounded corner allows you to:

• Fit cleanly into complex cabin layouts
• Improve movement in confined spaces
• Avoid sharp corners in tight environments

The combination of angled cut and rounded finish makes it particularly suited to marine use, where both fit and comfort are critical.

Fitted sheets are produced to match the same shape, ensuring a secure and practical fit.

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

Made to Measure Fitted Sheets for Complex Shaped Mattresses

This is where most suppliers fall down.

Standard fitted sheets are designed for rectangles — not angled and rounded shapes combined. They tend to:

• pull unevenly across the diagonal
• lift at the rounded corner
• come loose during use

Our fitted sheets are made specifically for this type of mattress:

• Cut to follow both the diagonal and rounded 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 in everyday use — not just something that fits once.

Foam Options Built for Consistent Support

With a combined shape like this, consistency matters.

We offer a range of foam grades to suit different needs and budgets, ensuring the mattress delivers even support across both the angled and rounded sections:

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

Each mattress is built to perform properly across its full shape.
