FROM £69.99
Our LHF Diagonal Cut-Off replacement mattress cover is designed for mattresses that feature a diagonal cut-away corner on the left-hand front side — a shape frequently used to maximise space in bespoke bed layouts in caravans, campervans, marine cabins and motorhomes.
Standard covers struggle with asymmetrical corners. That’s why we offer a made-to-measure solution, custom-created from your measurements for a snug, tailored fit that restores both appearance and hygiene — without replacing the entire mattress when the foam beneath is still in good condition.
Each cover is hand-made in the UK and crafted to your exact specifications for a professional finish every time.
Mattresses with diagonal cut-offs require a specialised pattern and cover. This product is constructed to:
Accommodate the diagonal cut-off corner
Fit varying depths and widths
Avoid loose edges or excess fabric
Wrap cleanly around non-standard angles
You provide the measurements, and we deliver a precise, custom cover that fits exactly without bunching, sagging, or distortion.
Perfect for:
Caravan beds with left diagonal cut-offs
Campervans with tailored sleeping areas
Boat cabins where shape matters
Motorhomes with unique mattress layouts
Choose from our range of performance fabrics designed for real-world environments:
CoolTech Cooling Fabric – helps regulate temperature and reduce heat build-up
Tencel™ Mattress Fabric – breathable, moisture-wicking, naturally comfortable
EasyClean Mattress Fabric – wipe-clean, durable for frequent use
All covers are:
Removable
Washable
Zip-fastened
Built for long-lasting performance
Caravans, campervans, boats and motorhomes often have limited airflow and higher humidity — particularly around uniquely shaped beds. A well-fitting replacement mattress cover improves hygiene and protects the underlying foam from environmental wear.
If your internal foam has lost support or comfort, you may prefer replacing the mattress entirely rather than just the cover.

(Also suitable for boats and other leisure vehicles.)
If you’re replacing the cover because of damp, condensation or mould, we strongly recommend adding a moisture-reducing mattress spacer underneath your mattress to improve airflow and reduce moisture build-up.
