RHF Diagonal Cut Off Memory Foam Topper – Made to Measure in the UK

If your mattress has a diagonal cut off corner, you’ll already know the problem — standard toppers simply don’t fit.

They overhang the angled section, leave unsupported areas, or never sit flat.

This RHF diagonal cut off memory foam topper is made to match that exact shape, with a clean angled cut designed to follow your mattress precisely — giving you a proper fit and a noticeable improvement in comfort.

Ideal for campervans, caravans and boats, where space is limited and layouts are rarely square.

Designed for Diagonal Cut Off Mattress Shapes

A diagonal cut off shape is used where:

• a corner is removed at a clean angle
• access around the bed is restricted
• space needs to be maximised without curves

You’ll typically find this in:

• campervan side conversions
• caravan fixed beds with access corners
• boat berths and marine sleeping areas
• compact custom layouts

Unlike curved or rounded shapes, this is a sharp, precise cut, which makes standard toppers unusable.

Each topper is:

• cut to your exact measurements
• shaped to match the angled cut precisely
• designed to sit flat with no gaps or overlap

A Practical Solution to an Uncomfortable Mattress

Most mattresses in campervans, caravans and boats are:

• too firm
• too thin
• worn unevenly over time

A made to measure memory foam topper helps:

• relieve pressure across shoulders and hips
• improve comfort on firm base cushions
• create a more forgiving sleep surface
• extend the life of your mattress

It’s a simple upgrade — but one that makes a real difference.

When a Topper Isn’t Enough

A topper improves comfort — but it won’t fix a mattress that has no support left.

If your mattress is:

• sagging
• completely worn out
• lacking structure

then the better long-term solution is to replace the mattress itself.

A common approach is:

• a supportive base mattress
• combined with a memory foam topper for comfort

This works particularly well in boats and campervans, where mattresses are often thinner and under more stress.

Cooling Covers That Make a Real Difference

Heat build-up is a common issue in campervans, caravans and boats — especially in enclosed sleeping spaces.

That’s why we offer:

Tencel Cooling Cover (Premium)

• breathable natural fibre
• moisture-wicking

• ideal for warm and confined environments

Cooltech Cover (Practical Option)

Complete Your Setup Properly

To get the most from your topper, you can also add:

• Tencel pillows for cooler, more comfortable sleep

• foam and cover packages for a complete ready-to-use solution

This creates a properly matched sleep system.
