Made-to-measure replacement mattress cover for Right Hand Front (RHF) diagonal cutaway mattresses, ideal for caravans, campervans, boats and motorhomes. Choose from 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 RHF Diagonal Cutaway replacement mattress cover is crafted for mattresses with a diagonal cutaway section on the right front side — a shape typically used in tailored bed layouts to maximise space and improve accessibility.
Standard covers simply don’t sit properly on these profiles, which is why we manufacture every cover to your exact measurements. The result is a snug, professional fit that restores hygiene and appearance without requiring a full mattress replacement when the internal foam is still in good condition.
Each cover is hand-made in the UK and constructed according to your supplied dimensions for the best possible fit.
Mattresses with a diagonal cutaway require a bespoke pattern and careful construction so the cover can:
Match the diagonal cutaway profile
Wrap smoothly around angled edges
Fit variations in depth and width
Avoid loose edges or excess fabric
Provide accurate measurements and we’ll deliver a custom replacement cover that fits perfectly — no bunching, sagging, or distortion.
Ideal for:
Caravan beds with RHF diagonal cutaway corners
Campervan sleeping areas with bespoke layouts
Boat cabins with non-standard mattress designs
Motorhomes with unique mattress layouts
Choose the fabric that matches your environment and comfort needs:
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 and practical for frequent use
All covers are:
Removable
Washable
Zip-fastened
Built for long-lasting performance
Caravans, campervans, boats and motorhomes often face higher humidity and limited airflow — especially around custom mattress shapes. A well-fitting replacement cover greatly improves hygiene and helps protect the foam beneath from environmental conditions.
If your internal foam has lost support or cushioning, you may prefer to replace the mattress rather than just the cover.

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