Made-to-measure replacement cover for Left Hand Front (LHF) twin diagonal cutaway mattresses — ideal for caravans, campervans, boats and motorhomes. Available in CoolTech, Tencel™ or EasyClean fabrics — all washable, zip-fastened, removable and hand-made in the UK.
All colour option only apply to EasyClean
FROM £69.99
Our LHF Twin Diagonal Cutaway replacement mattress cover has been specifically designed for mattresses with a left-hand front twin diagonal cutaway shape — a variation often found in unconventional sleeping spaces where two diagonally cut sections are combined for maximum comfort and access.
Standard covers won’t fit these shapes correctly, which is why we manufacture each cover to your exact measurements. This delivers a clean, snug fit that restores hygiene and appearance without necessitating a full mattress replacement — assuming the existing foam is still supportive.
Every cover is hand-made in the UK and cut and sewn to your precise dimensions for a professional finish.
Mattresses with a twin diagonal cutaway have complex angles and require a specialist pattern. This cover is crafted to:
Accommodate dual diagonal cutaway sections
Maintain clean lines without excess fabric
Match varying depth and width
Wrap smoothly around non-standard edges
Simply supply your measurements and we’ll deliver a custom replacement cover that fits perfectly — no bunching, sagging, or distortion.
Perfect for:
Caravan beds with twin diagonal cutaways
Campervan sleeping areas with bespoke layouts
Boat cabins with optimised mattress footprints
Motorhomes with unique mattress outlines
Choose the fabric that suits your environment and comfort needs:

All covers are:
Removable
Washable
Zip-fastened
Designed for long-lasting performance
Caravans, campervans, boats and motorhomes often face limited airflow and higher humidity — particularly around uniquely shaped beds. A well-fitting mattress cover enhances sleep hygiene and helps protect the foam beneath from environmental wear.
If your internal foam has lost support or cushioning, you may prefer replacing the mattress altogether 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 beneath your mattress, which helps:
Improve airflow
Reduce moisture build-up
Prevent future mould and mildew
Extend the life of both foam and cover
