Our LHF Diagonal Square Rectangle Split replacement mattress cover is tailored for mattresses with a complex diagonal and square/rectangle split shape on the left front side — a geometry often found in custom bed zones designed to maximise space and comfort in tight layouts like caravans and boats.
Standard covers simply won’t sit cleanly on these layouts. That’s why we make every cover to measure, using the exact dimensions you provide to deliver a snug, professional fit that restores hygiene and appearance — without replacing the entire mattress if the internal foam is still in good condition.
Each cover is hand-made in the UK, cut and stitched to your precise specifications for a high-quality finish.
Mattresses with a diagonal square-rectangle split require a specialist cover pattern to:
Match the diagonal split profile
Align varying depth and width sections
Maintain structure without loose or excess fabric
Wrap cleanly around both squared and angled edges
With accurate measurements supplied by you, we produce a custom cover that fits perfectly — no bunching, sagging, or distortion.
Perfect for:
Caravan beds with custom split shapes
Campervan sleeping areas with multi-angled designs
Boat cabins with optimised bed footprints
Motorhomes with irregular mattress outlines
Choose your preferred performance fabric for environment and comfort:
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
Beds in caravans, campervans, boats and motorhomes are exposed to more demanding conditions — limited airflow, humidity, and frequent use — especially in non-standard mattress shapes. A well-fitting replacement cover enhances hygiene and protects the foam beneath.
If the internal foam has lost support or cushioning, you may want to replace the mattress rather than just the cover.

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