Custom D-Shape Memory Foam Topper – Made to Measure for Campervans, Caravans & Boats

A Perfect Fit for Awkward Bed Shapes

The D-shape memory foam topper is designed for beds where a standard rectangle simply won’t work.

Common in campervans, caravans and boats, D-shaped sleeping areas often feature a curved edge to maximise space. This topper is cut precisely to follow that curve, giving you a clean, tailored fit without gaps or overhang.

Upgrade Comfort Without Replacing Your Mattress

If your existing mattress feels too firm or uncomfortable, a memory foam topper is a simple and effective upgrade.

• Helps reduce pressure points
• Improves overall sleep comfort
• Adds a softer, more supportive surface
• Ideal for thin or firm leisure mattresses

This is particularly useful in campervans and boats where mattress thickness is often limited.

Designed for Real-World Use

The D-shape topper is commonly used in:

• Campervan rear beds with curved layouts
• Caravan island and corner beds
• Boat berths where space is restricted
• Custom-built sleeping platforms

By following the exact shape of your mattress, it maintains usable space while improving comfort.

Made to Measure for a Precise Fit

Every topper is cut to your exact dimensions, including the curved D-shape edge.

This ensures:

• A snug, accurate fit
• No wasted space
• A professional finish within your setup

Simply provide your measurements and we’ll do the rest.

Important – A Topper Is Not a Replacement Mattress

A memory foam topper enhances comfort, but it relies on the support of the mattress beneath it.

If your mattress is sagging or lacks structure, replacing the mattress will give better long-term results.

For best performance, use this topper with a firm, supportive base.

Perfect for Campervan & Marine Environments

Space is always at a premium in vans and boats. This topper is designed to improve comfort without adding unnecessary bulk.

It works particularly well where:

• Mattress thickness is restricted
• Sleeping areas are irregular in shape
• Comfort needs improving without a full refit

Thickness & Practical Considerations

We offer practical thickness options suited to leisure use.

Before ordering, consider:

• Available headroom
• Whether your pop-top or roof will still close
• Storage when not in use

A well-chosen topper improves comfort without creating new problems.

Cooling Tencel Cover
A premium natural fibre cover designed to regulate temperature and improve breathability—ideal for warmer nights in campervans and roof tents.
